Definitions
- the invention relates to a multilayer label having a splittable layer.
- Information labels are, as the name suggests, information, mostly in the printing process. To apply these labels on a substrate, they have a pressure-sensitive adhesive layer, which fixes the label after the dispensing process.
- An optimized variant of a label is characterized by the fact that the carrier of the label is printed on top and bottom side. To get to the information on the bottom, the label must be separable. For this purpose, the label is designed such that the carrier can be removed from the adhesive.
- the disadvantage is that an open adhesive remains on the ground, which tends to foul or adhere to the undesirable things.
- a laminating adhesive is applied for this purpose between adhesive and carrier. Subsequently, the laminating adhesive is cured (for example, by UV light or thermal), so that the laminating adhesive after irreversible curing no longer has pressure-sensitive adhesive properties.
- the bond between the carrier and laminating adhesive is preferably designed so that the carrier is removable from the laminating adhesive. Then he stays Laminating adhesive without adhesive properties on the adhesive, the disadvantages described do not occur.
- the carrier is printed on the top and bottom sides. Both layers are brought together and a compound is formed between two of the print layers. When separating the label, this splits between the print layers, so that the adhesive is still covered.
- VID labels which are used as a security label and indicate unauthorized opening of packages or the like.
- the deformations during the cleavage process mean that the layers can not be brought over one another after separation, so that even after re-gluing the lettering or the like remain recognizable and thus the unauthorized opening is signaled.
- the usually single-layer labels are constructed in such a way that certain portions of the label base are equipped with a primer and others are not.
- a paint separates on removal of a bonded label from the film side and remains on the adhesive.
- the US 2002/0176975 A1 describes a security tag which can be separated along a fissile layer.
- the EP 1 403 190 A2 discloses a tamper-evident seal with a splittable backing which irreversibly splits the backing upon breaking the tamper-evident seal.
- Object of the present invention is to provide a label that is easy to open, which provides a lot of space for printing and leaves after leaving no free adhesive surface.
- the invention relates to a multilayer label with a carrier whose upper side is printed with a first print layer and on the lower side of the layers according to claim 1 are applied in the specified descending order.
- the second print layer is applied to the carrier, more preferably the first and second print layers simultaneously.
- a protective lacquer layer is present between the support or the second printing layer and the gap-capable printing layer.
- the weakest link within the label is represented by the splittable print layer. Between all layers of the label, the bond is stronger than the cohesion within the splittable print layer.
- the individual layers are also designed in such a way that no cohesive fracture can be observed in them.
- the bond strength with which the label can be adhered to the substrate is also higher than the cohesion in the splittable layer, so that the entire label does not peel off from the substrate during the opening attempt of the bonded label, but the label is actually in the splittable printing layer splits.
- the bond strength with which the label can be adhered to the substrate is also higher than the cohesion in the splittable layer, so that the entire label does not peel off from the substrate during the opening attempt of the bonded label, but the label is actually in the splittable printing layer splits.
- use cases are conceivable where it is possible to dispense with a column of the label, that is, the removal has higher priority.
- the first, second and third print layers carry the information that is to be disseminated through the label. They can also consist of several individual layers, which are printed one after the other and which can have different colors. The pressure can be next to or to each other.
- the first, second and third printed layers are partially applied.
- the protective lacquer layer serves to protect the second print layer.
- the Klebemassenabdeck für serves to tap the adhesive side facing the label side of the adhesive layer, since this is covered by the imprint of the layer.
- the cleavable printing layer, the adhesive compound covering layer and, if appropriate, the protective lacquer layer are applied over the entire surface of the support.
- the third printing layer may be printed on the cleavable printing layer, preferably it is printed on the adhesive layer, so that the Klebemassenabdeck harsh protects the third printed layer.
- the pressure-sensitive adhesive is applied to the Klebemassenabdeck für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für adstand für abdeck

- optionally the third printing layer optionally the third printing layer.
- This adhesive mass-free projecting region on the adhesive mass covering layer and optionally on the third printing layer can serve as a handle if - after the separation of the label - also the Klebemassenabdeck harsh including the third printing layer should be removed from the substrate.
- the bond between the adhesive compound covering layer and optionally the third printing layer and the PSA is stronger than the adhesive force with which the label is glued to the substrate.
- a non-adhesive strip can be produced on the PSA layer by partially rendering the adhesive in the region inactivated (for example by irradiation, powdering or partial neutralization).
- a low tack streak can also be achieved by using two different adhesives within the adhesive layer.
- a removable adhesive having low bond strength is used in the area in which the grip is to be formed.
- a second handle may be provided on the carrier layer.
- an area on the underside of the substrate in this area is not coated or the bond to the underlying layer is weakened. the. This area then serves as a handle for grasping and peeling off the wearer.
- This grip can also be formed in that an additional, preferably uncoated surface is formed on the carrier.
- the cleavable printing layer, the Klebemassenabdeck harsh and the third printing layer are partially applied so that PSA is in contact at least in an edge region of the label with the overlying the cleavable printing layer.
- the splittable layer When the label is opened, the splittable layer, while no cohesive failure is observed in the adhesive layer, does not split even in the region in which the adhesive with the layer above the cleavable printing layer is in Contact stands. This area rather forms a hinge, over which the label can be opened and closed.
- this adhesive tape is 5 mm wide in the edge region of the label.
- the hinge preferably lies opposite the adhesive-mass-free area forming a grip and / or the grip formed on the support.
- a second recess is additionally present in the cleavable printing layer, in the adhesive mass covering layer and in the third printing layer so that the pressure-sensitive adhesive is in contact with the layer located above the cleavable printing layer in a second area.
- This recess may be cylindrical (for example, with an oval base), in particular circular cylindrical and should have a small area compared to the total area of the label.
- This recess is in relation to the described strip of adhesive, which forms the hinge, as close as possible to the opposite edge of the label, because this area allows a reversible bonding of the opened label, so that a previously opened label can be closed again at this point and a "fluttering" and kinking of the label can be prevented.
- the label is additionally provided with an additional and variable printing by means of a further printing method, such as, for example, an inkjet printing (preferred), a laser marking or a thermal transfer printing.

- the label consists of only one carrier layer, preferably a film layer, an adhesive layer and various print layers, the material thickness is significantly thinner compared to the conventional labels. This advantage makes it much easier and trouble-free to process the label material with the classic labeling machines.
- the label applied to the substrate can be removed without residue and without pressure-sensitive adhesive properties.
- the carrier is usually placed in a reversible composite with a self-adhesive material. This results in a relatively stiff and possibly difficult to process material.

- the carrier 2 or the second printing layer 3 are covered with a protective lacquer layer 4 applied over the entire surface.
- a cleavable printing layer 5 is applied over the entire surface, wherein the force for inducing the cohesive failure within the cleavable printing layer 5 is smaller than the forces with which the cleavable printing layer 5 is connected to the overlying and the underlying layer 4 and 7 , This force is also smaller than any force associated with each of two superposed layers within the label.
- a third printing layer 6 is provided, which is also partially printed. This information is accessible to the customer only after separation of the label 10. Since the third printing layer 6 also consists of only one layer, the imprint is again monochrome.
- the third printing layer 6 is printed on the layer of adhesive layer 8, so that the third printing layer 6 is protected by the overlying adhesive layer covering layer 7.

- the cleavable printing layer 5, the adhesive compound covering layer 7 and the third printing layer 6 are absent in an edge region of the label 10, namely the adhesive mass-free region 14, so that the PSA layer 8 in this edge region of the label 10 with the layer above the cleavable printing layer 5 4 is in contact.
- the hinge can be separated.
- FIG. 5 shows the multilayer label 10 in another preferred embodiment in the lateral section.
- the structure of the label 10 corresponds to that of the FIG. 3 is known.
- an additional second recess 82 is present, so that the pressure-sensitive adhesive 8 in a second region 82 with the above the splittable Print layer 5 lying layer 4 is in contact.

Description
Die Erfindung betrifft ein mehrschichtiges Etikett, das eine spaltfähige Schicht aufweist.The invention relates to a multilayer label having a splittable layer.

Um diese Etiketten auf einem Untergrund aufzubringen, weisen diese eine haftklebende Schicht auf, die das Etikett nach dem Spendevorgang fixiert.Information labels are, as the name suggests, information, mostly in the printing process. To apply these labels on a substrate, they have a pressure-sensitive adhesive layer, which fixes the label after the dispensing process.
Bei herkömmlichen Etiketten steht somit nur die Oberfläche des Etiketts als Druckbereich zur Verfügung.In conventional labels, therefore, only the surface of the label is available as a printing area.
Eine optimierte Variante eines Etiketts zeichnet sich, dadurch aus, dass der Träger des Etiketts ober- und unterseitig bedruckt ist. Um an die Information auf der Unterseite zu gelangen, muss das Etikett auftrennbar sein. Dazu wird das Etikett derart gestaltet, dass der Träger von der Klebemasse abgezogen werden kann. Nachteilig ist, dass auf dem Untergrund eine offene Klebemasse verbleibt, die zum Verschmutzen neigt oder auf der unerwünscht Dinge haften bleiben.An optimized variant of a label is characterized by the fact that the carrier of the label is printed on top and bottom side. To get to the information on the bottom, the label must be separable. For this purpose, the label is designed such that the carrier can be removed from the adhesive. The disadvantage is that an open adhesive remains on the ground, which tends to foul or adhere to the undesirable things.
Um dies zu verhindern, gibt es Etiketten, bei denen die Haftklebemasse nach der Auftrennung nicht haftklebrig zurückbleibt. Beispielsweise wird hierzu zwischen Klebemasse und Träger ein Kaschierkleber aufgebracht. Im Anschluss wird der Kaschierkleber ausgehärtet (zum Beispiel durch UV-Licht oder thermisch), so dass der Kaschierkleber nach dem irreversiblen Aushärten keine haftklebrigen Eigenschaften mehr besitzt.In order to prevent this, there are labels in which the PSA does not remain tacky after separation. For example, a laminating adhesive is applied for this purpose between adhesive and carrier. Subsequently, the laminating adhesive is cured (for example, by UV light or thermal), so that the laminating adhesive after irreversible curing no longer has pressure-sensitive adhesive properties.
Die Verbundhaftung zwischen dem Träger und Kaschierkleber ist vorzugsweise so ausgelegt, dass der Träger vom Kaschierkleber abziehbar ist. Dann verbleibt der Kaschierkleber ohne haftklebrige Eigenschaften auf der Klebemasse, die geschilderten Nachteile treten nicht auf.The bond between the carrier and laminating adhesive is preferably designed so that the carrier is removable from the laminating adhesive. Then he stays Laminating adhesive without adhesive properties on the adhesive, the disadvantages described do not occur.
Daneben gibt es Etiketten, bei denen dem Kunden die Möglichkeit geboten wird, möglichst viele Informationen auf verhältnismässig kleinem Raum unterzubringen. Dazu wird die Klebemasse, die das Etikett auf dem Untergrund fixiert, auf der Oberseite mit den gewünschten Informationen bedruckt.In addition, there are labels in which the customer is offered the opportunity to accommodate as much information in a relatively small space. For this purpose, the adhesive, which fixes the label on the substrate, printed on the top with the desired information.
Der Träger wird ober- und unterseitig bedruckt. Beide Lagen werden zusammengeführt, und es bildet sich zwischen zwei der Druckschichten eine Verbindung aus. Beim Auftrennen des Etiketts spaltet diese zwischen den Druckschichten, so dass der Kleber weiterhin abgedeckt ist.The carrier is printed on the top and bottom sides. Both layers are brought together and a compound is formed between two of the print layers. When separating the label, this splits between the print layers, so that the adhesive is still covered.
Des Weiteren existieren so genannte "VOID-Etiketten", die als Sicherheitsetikett angewendet werden und nicht autorisiertes Öffnen von Verpackungen oder Ähnliches anzeigen.Furthermore, there are so-called "VOID labels" which are used as a security label and indicate unauthorized opening of packages or the like.
Wird das verklebte, meistens farbige "VOID-Etikett" vom Substrat entfernt, so findet ein definiertes Spalten der Farb- und Klebstoffschichten zwischen Trägermaterial und Substrat statt und ein spezifischer Schriftzug oder Ähnliches erscheint.If the bonded, mostly colored "VOID label" is removed from the substrate, a defined splitting of the color and adhesive layers between the carrier material and the substrate takes place and a specific lettering or the like appears.
Die Deformationen während des Spaltprozesses führen dazu, dass die Schichten nach dem Trennen nicht mehr deckungsgleich übereinander gebracht werden können, so dass auch nach erneutem Verkleben der Schriftzug oder Ähnliches erkennbar bleiben und somit das unautorisierte Öffnen signalisiert wird.The deformations during the cleavage process mean that the layers can not be brought over one another after separation, so that even after re-gluing the lettering or the like remain recognizable and thus the unauthorized opening is signaled.
Die üblicherweise einlagigen Etiketten sind in der Art aufgebaut, dass bestimmte Teilbereiche der Etikettenunterseite mit einem Haftvermittler ausgerüstet sind und andere nicht. Durch dieses unterschiedliche Haftvermögen der Folienunterseite trennt sich beispielsweise eine Farbe beim Entfernen eines verklebten Etiketts von der Folienseite und verbleibt auf der Klebmasse.The usually single-layer labels are constructed in such a way that certain portions of the label base are equipped with a primer and others are not. By virtue of this different adhesion of the underside of the film, for example, a paint separates on removal of a bonded label from the film side and remains on the adhesive.
Da die Farbe nach dem Trennen auch ihre formschlüssige Verbindung zur Folie verloren hat und gegebenenfalls noch Dehnungseffekte zu Dimensionsänderungen geführt haben, bleibt der Schriftzug auch nach einem erneuten Verkleben durch Lufteinschlüsse beziehungsweise Deformationen erkennbar.Since the color has also lost its positive connection to the film after the separation and, if necessary, elongation effects have led to dimensional changes, the lettering remains recognizable even after renewed sticking due to air inclusions or deformations.

Aufgabe der vorliegenden Erfindung ist es, ein Etikett zu schaffen, das leicht zu öffnen ist, das viel Fläche zum Bedrucken zur Verfügung stellt und das nach dem Öffnen keine freie Klebefläche zurücklässt.Object of the present invention is to provide a label that is easy to open, which provides a lot of space for printing and leaves after leaving no free adhesive surface.
Gelöst wird diese Aufgabe durch ein Etikett bzw. Verfahren, wie es im Hauptanspruch 1 bzw. 17 dargelegt ist. Gegenstand der Unteransprüche sind vorteilhafte Fortbildungen des Erfindungsgegenstandes. Des Weiteren betrifft die Erfindung Verwendungsvorschläge des erfindungsgemäßen Etiketts.This object is achieved by a label or method, as set forth in the main claim 1 and 17. The subject of the dependent claims are advantageous developments of the subject invention. Furthermore, the invention relates to proposed uses of the label according to the invention.
Demgemäß betrifft die Erfindung ein mehrschichtiges Etikett mit einem Träger, dessen obere Seite mit einer ersten Druckschicht bedruckt ist und auf dessen unterer Seite die Schichten gemäss Anspruch 1 in der angegeben absteigenden Reihenfolge aufgebracht sind.Accordingly, the invention relates to a multilayer label with a carrier whose upper side is printed with a first print layer and on the lower side of the layers according to claim 1 are applied in the specified descending order.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist die zweite Druckschicht auf dem Träger aufgebracht, weiter vorzugsweise die erste und zweite Druckschichten gleichzeitig.According to an advantageous embodiment of the invention, the second print layer is applied to the carrier, more preferably the first and second print layers simultaneously.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist zwischen Träger beziehungsweise zweiter Druckschicht und spaltfähiger Druckschicht eine Schutzlackschicht vorhanden.According to an advantageous embodiment of the invention, a protective lacquer layer is present between the support or the second printing layer and the gap-capable printing layer.
Das schwächste Glied innerhalb des Etiketts wird von der spaltfähigen Druckschicht dargestellt. Zwischen allen Schichten des Etiketts ist der Verbund stärker als die Kohäsion innerhalb der spaltfähigen Druckschicht. Auch sind die einzelnen Schichten derart ausgestaltet, dass in ihnen kein kohäsiver Bruch zu beobachten ist.The weakest link within the label is represented by the splittable print layer. Between all layers of the label, the bond is stronger than the cohesion within the splittable print layer. The individual layers are also designed in such a way that no cohesive fracture can be observed in them.
Bevorzugt ist die Klebkraft, mit der das Etikett auf dem Untergrund verklebt werden kann, ebenfalls höher als die Kohäsion in der spaltfähigen Schicht, so dass sich beim Öffnungsversuch des verklebten Etiketts nicht das gesamte Etikett vom Untergrund abschält, sondern das Etikett tatsächlich in der spaltfähigen Druckschicht spaltet. Allerdings sind auch Anwendungsfälle denkbar, wo auf ein Spalten des Etiketts verzichtet werden kann, sprich das Entfernen höhere Priorität hat.Preferably, the bond strength with which the label can be adhered to the substrate is also higher than the cohesion in the splittable layer, so that the entire label does not peel off from the substrate during the opening attempt of the bonded label, but the label is actually in the splittable printing layer splits. However, use cases are conceivable where it is possible to dispense with a column of the label, that is, the removal has higher priority.
Die erste, zweite und dritte Druckschicht tragen die Informationen, die durch das Etikett verbreitet werden sollen. Sie können auch aus mehreren einzelnen Lagen bestehen, die nacheinander gedruckt werden und die unterschiedliche Farben aufweisen können. Der Druck kann dabei neben- oder aufeinander erfolgen.The first, second and third print layers carry the information that is to be disseminated through the label. They can also consist of several individual layers, which are printed one after the other and which can have different colors. The pressure can be next to or to each other.
Vorzugsweise sind die erste, zweite und dritte Druckschicht partiell aufgebracht.Preferably, the first, second and third printed layers are partially applied.
Die Schutzlackschicht dient dazu, die zweite Druckschicht zu schützen.The protective lacquer layer serves to protect the second print layer.
Die Klebemassenabdeckschicht dient dazu, die zum Etikett gewandte Seite der Klebemassenschicht klebtechnisch zu neutralisieren, da diese durch den Aufdruck der Schicht abgedeckt wird.The Klebemassenabdeckschicht serves to tap the adhesive side facing the label side of the adhesive layer, since this is covered by the imprint of the layer.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind die spaltfähige Druckschicht, die Klebemassenabdeckschicht sowie gegebenenfalls die Schutzlackschicht vollflächig auf dem Träger aufgebracht.According to a further preferred embodiment of the invention, the cleavable printing layer, the adhesive compound covering layer and, if appropriate, the protective lacquer layer are applied over the entire surface of the support.
Die dritte Druckschicht kann auf der spaltfähigen Druckschicht aufgedruckt sein, bevorzugt wird diese auf der Klebemassenschicht aufgedruckt, so dass die Klebemassenabdeckschicht die dritte Druckschicht schützt.The third printing layer may be printed on the cleavable printing layer, preferably it is printed on the adhesive layer, so that the Klebemassenabdeckschicht protects the third printed layer.
Weiter vorzugsweise ist die Haftklebemasse auf der Klebemassenabdeckschicht beziehungsweise der dritten Druckschicht derart aufgebracht, dass in einem Randbereich des Etiketts ein klebemassenfreier Steifen auf der Klebemassenabdeckschicht sowie gegebenenfalls der dritten Druckschicht ist.Further preferably, the pressure-sensitive adhesive is applied to the Klebemassenabdeckschicht or the third printing layer such that in an edge region the label is a Klebemassenfreier stiffening on the Klebemassenabdeckschicht and optionally the third printing layer.
Dieser klebemassenfreie überstehende Bereich an der Klebemassenabdeckschicht sowie gegebenenfalls an der dritten Druckschicht kann als Anfasser dienen, wenn - nach der Auftrennung des Etiketts - auch die Klebemassenabdeckschicht samt der dritten Druckschicht vom Untergrund entfernt werden soll.This adhesive mass-free projecting region on the adhesive mass covering layer and optionally on the third printing layer can serve as a handle if - after the separation of the label - also the Klebemassenabdeckschicht including the third printing layer should be removed from the substrate.
Um die Klebemasse gleichzeitig zu entfernen, ist es vorteilhaft, wenn der Verbund zwischen der Klebemassenabdeckschicht sowie gegebenenfalls der dritten Druckschicht und der Haftklebemasse stärker ist als die Klebekraft, mit der das Etikett auf dem Untergrund verklebt ist.In order to remove the adhesive at the same time, it is advantageous if the bond between the adhesive compound covering layer and optionally the third printing layer and the PSA is stronger than the adhesive force with which the label is glued to the substrate.
Statt den Streifen nicht mit einer Klebemasse auszurüsten, kann ein nichtklebender Streifen auf der Haftklebemassenschicht erzeugt werden, indem die Klebemasse in dem Bereich partiell inaktiviert (beispielsweise durch Bestrahlung, Bepuderung oder Teilneutralisation) wird.Instead of providing the strip with an adhesive, a non-adhesive strip can be produced on the PSA layer by partially rendering the adhesive in the region inactivated (for example by irradiation, powdering or partial neutralization).
Ein schwach klebender Streifen kann auch durch den Einsatz von zwei unterschiedlichen Klebstoffen innerhalb der Klebstoffschicht erreicht werden. Hierzu wird ein ablösbarer, geringe Klebkräfte aufweisender Kleber in dem Bereich eingesetzt, in dem der Anfasser gebildet werden soll.A low tack streak can also be achieved by using two different adhesives within the adhesive layer. For this purpose, a removable adhesive having low bond strength is used in the area in which the grip is to be formed.
Ein zweiter Anfasser kann an der Trägerschicht vorgesehen sein.A second handle may be provided on the carrier layer.
Vorzugsweise ist auf der Unterseite des Trägermaterials in diesem Bereich eine Fläche nicht beschichtet oder die Bindung zu der darunter liegenden Schicht ist geschwächt. die. Diese Fläche dient dann als Anfasser zum Greifen und Abziehen des Trägers.Preferably, an area on the underside of the substrate in this area is not coated or the bond to the underlying layer is weakened. the. This area then serves as a handle for grasping and peeling off the wearer.
Dieser Anfasser kann auch dadurch gebildet werden, dass an dem Träger eine zusätzliche, vorzugsweise unbeschichtete Fläche angeformt ist.This grip can also be formed in that an additional, preferably uncoated surface is formed on the carrier.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung sind die spaltfähige Druckschicht, die Klebemassenabdeckschicht und die dritte Druckschicht partiell derart aufgebracht, dass Haftklebemasse zumindest in einem Randbereich des Etiketts mit der über der spaltfähigen Druckschicht liegenden Schicht in Kontakt steht.According to a further advantageous embodiment of the invention, the cleavable printing layer, the Klebemassenabdeckschicht and the third printing layer are partially applied so that PSA is in contact at least in an edge region of the label with the overlying the cleavable printing layer.
Beim Öffnen des Etiketts spaltet die spaltfähige Schicht, während in der Klebemasseschicht kein Kohäsionsbruch zu beobachten ist, auch nicht in dem Bereich, in dem die Klebemasse mit der über der spaltfähigen Druckschicht liegenden Schicht in Kontakt steht. Dieser Bereich bildet vielmehr ein Scharnier, über das das Etikett auf- und zugeklappt werden kann.When the label is opened, the splittable layer, while no cohesive failure is observed in the adhesive layer, does not split even in the region in which the adhesive with the layer above the cleavable printing layer is in Contact stands. This area rather forms a hinge, over which the label can be opened and closed.
Beispielsweise ist dieser Klebemassestreifen im Randbereich des Etiketts 5 mm breit. Vorzugsweise liegt das Scharnier dem klebemassefreien, einen Anfasser bildenden Bereich gegenüber und/oder dem am Träger gebildeten Anfasser.For example, this adhesive tape is 5 mm wide in the edge region of the label. The hinge preferably lies opposite the adhesive-mass-free area forming a grip and / or the grip formed on the support.
In einer vorteilhaften Fortbildung der beschriebenen Ausführungsform ist in der spaltfähigen Druckschicht, in der Klebemassenabdeckschicht und in der dritten Druckschicht zusätzlich eine zweite Aussparung vorhanden, so dass die Haftklebemasse in einem zweiten Bereich mit der über der spaltfähigen Druckschicht liegenden Schicht in Kontakt steht. Diese Aussparung kann zylindrisch (beispielsweise mit ovaler Grundfläche), insbesondere kreiszylinderförmig sein und sollte im Vergleich zur Gesamtfläche des Etiketts eine kleine Fläche aufweisen. Diese Aussparung liegt in Bezug auf den beschriebenen Streifen Klebemasse, der das Scharnier bildet, möglichst in der Nähe des gegenüberliegenden Randes des Etiketts, weil dieser Bereich eine reversible Verklebung des geöffneten Etiketts ermöglicht, so dass ein vormals geöffnetes Etikett an dieser Stelle wieder verschlossen werden kann und ein "Aufflattern" und Verknicken des Etiketts verhindert werden kann.In an advantageous further development of the embodiment described, a second recess is additionally present in the cleavable printing layer, in the adhesive mass covering layer and in the third printing layer so that the pressure-sensitive adhesive is in contact with the layer located above the cleavable printing layer in a second area. This recess may be cylindrical (for example, with an oval base), in particular circular cylindrical and should have a small area compared to the total area of the label. This recess is in relation to the described strip of adhesive, which forms the hinge, as close as possible to the opposite edge of the label, because this area allows a reversible bonding of the opened label, so that a previously opened label can be closed again at this point and a "fluttering" and kinking of the label can be prevented.
Aufgrund des geschilderten Zwecks dieses Bereiches wählt der Fachmann in Abhängigkeit von der Größe des Etiketts sowie von der verwendeten Klebemasse eine passende Fläche für die Aussparung. Der dem Öffnen des Etiketts entgegen gesetzte Widerstand darf nicht zu groß sein, auf der anderen Seite muss die Fläche ausreichen, um ein Wiederverkleben des Etiketts zu sicherzustellen.Due to the described purpose of this area, the skilled person selects a suitable area for the recess, depending on the size of the label and on the adhesive used. The resistance opposed to opening the label must not be too great; on the other hand, the area must be sufficient to ensure that the label is re-bonded.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung wird das Etikett zusätzlich über ein weiteres Druckverfahren wie zum Beispiel einer InkJet-Bedruckung (bevorzugt), einer Lasermarkierung oder einer Thermotransferbedruckung mit einer zusätzlichen und variablen Bedruckung versehen. Beispielsweise handelt es sich um alphabetische, numerische oder alphanumerische Codes, Logistik-Codes, EAN-Codes, Bar-Codes etc., um das erfindungsgemäße Etikett für Gewinnspiele, Preisauszeichnungen, logistische Zwecke etc. einsetzen zu können.According to a further advantageous embodiment of the invention, the label is additionally provided with an additional and variable printing by means of a further printing method, such as, for example, an inkjet printing (preferred), a laser marking or a thermal transfer printing. For example, it is alphabetic, numeric or alphanumeric codes, logistics codes, EAN codes, bar codes, etc., to use the inventive label for competitions, pricing, logistics purposes, etc. can.
Diese Bedruckung ist insbesondere in der zweiten oder besonders bevorzugt in der dritten Druckschicht integriert, so dass diese nicht sofort sichtbar ist, sondern erst, nachdem das Etikett geöffnet worden ist. Die Bedruckung kann auch auf der zweiten oder dritten Druckschicht aufgebracht sein.This printing is integrated in particular in the second or particularly preferred in the third printing layer, so that it is not immediately visible, but only after the label has been opened. The printing can also be applied to the second or third printing layer.
Die erfindungsgemäßen Etiketten können kreisrund sein, beispielsweise mit einem Durchmesser von 30 mm, oval, viel- oder rechteckig sowie quadratisch sein, wobei letztere darüber hinaus auch abgerundete Ecken aufweisen können.The labels according to the invention may be circular, for example with a diameter of 30 mm, oval, polygonal or rectangular and square, the latter moreover also having rounded corners.
Die äußere Form der Etiketten ist nahezu uneingeschränkt dem jeweiligen Einsatzzweck angepasst variierbar.The outer shape of the labels can be varied almost unrestrictedly adapted to the respective application.
Als Träger des Etiketts stehen Papiere oder verschiedene Folien zur Auswahl.As a carrier of the label are papers or different slides to choose from.
Erfindungsgemäß als Materialien lassen sich Folien einsetzen, insbesondere monoaxial und biaxial gereckte Folien auf Basis von Polyolefinen, dann Folien auf Basis von gerecktem Polyethylen oder gereckten Copolymeren, enthaltend Ethylen- und/oder Polypropyleneinheiten, gegebenenfalls auch PVC-Folien, PET-Folien, Folien auf Basis von Vinylpolymeren, Polyamiden, Polyester, Polyacetalen, PolycarbonatenAccording to the invention can be used as materials films, in particular monoaxially and biaxially oriented films based on polyolefins, then films based on stretched polyethylene or stretched copolymers containing ethylene and / or polypropylene units, optionally also PVC films, PET films, films Base of vinyl polymers, polyamides, polyesters, polyacetals, polycarbonates

Bevorzugt zur Herstellung der erfindungsgemäßen Etiketten sind biaxial gereckte Folien auf Basis von Polypropylen. Die Dicken der biaxial gereckten Folien auf Basis von Polypropylen liegen bevorzugt zwischen 20 und 100 µm, besonders zwischen 25 und 75 µm, ganz besonders zwischen 30 und 65 µm.Biaxially oriented polypropylene is characterized by its very high tensile strength and low elongation. Preferred for the production of the labels according to the invention are biaxially oriented films based on polypropylene. The thicknesses of the biaxially oriented films based on polypropylene are preferably between 20 and 100 μm, in particular between 25 and 75 μm, very particularly between 30 and 65 μm.
Biaxial gereckte Folien auf Basis von Polypropylen können mittels Blasfolienextrusion oder mittels üblicher Flachfolienanlagen hergestellt werden. Biaxial gereckte Folien werden sowohl ein- als auch mehrschichtig hergestellt. Im Falle der mehrschichtigen Folien können auch hier die Dicke und Zusammensetzung der verschiedenen Schichten gleich sein aber auch verschiedene Dicken und Zusammensetzungen sind bekannt.Biaxially oriented films based on polypropylene can be produced by blown film extrusion or by means of conventional flat film systems. Biaxially stretched films are produced in one or more layers. In the case of multilayer films, the thickness and composition of the different layers may be the same, but also different thicknesses and compositions are known.
Geeignet für die erfindungsgemäßen Etiketten sind einschichtige, biaxial oder monoaxial gereckte Folien oder mehrschichtige, biaxiale oder monoaxiale Folien auf Basis von Polypropylen, die einen ausreichend festen Verbund zwischen den Schichten aufweisen, da ein Delaminieren der Schichten während der Anwendung nachteilig ist.Suitable for the labels according to the invention are monolayer, biaxially or monoaxially stretched films or multilayer, biaxial or monoaxial films based on polypropylene, which have a sufficiently strong bond between the layers, since delamination of the layers during use is disadvantageous.
Folien auf Basis von Hart-PVC werden zur Herstellung von Etiketten ebenso verwendet wie Folien auf Basis von Weich-PVC.Films based on rigid PVC are used for the production of labels as well as films based on soft PVC.
Für die erfindungsgemäßen Etiketten können auch Folien auf Basis von Hart-PVC verwendet werden. Die Dicken der Folien liegen bevorzugt zwischen 20 und 100 µm besonders zwischen 25 und 65 µm, ganz besonders zwischen 30 und 60 µm.For the labels according to the invention also films based on rigid PVC can be used. The thicknesses of the films are preferably between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.
Folien auf Polyesterbasis, zum Beispiel Polyethylenterephthalat sind ebenfalls bekannt und können ebenso zur Herstellung der erfindungsgemäßen Etiketten eingesetzt werden. Die Dicken der Folien auf Basis von PET liegen zwischen 20 und 100 µm, besonders zwischen 25 und 65 µm, ganz besonders zwischen 30 und 60 µm.Polyester-based films, for example polyethylene terephthalate, are also known and can also be used to make the labels of the invention. The thicknesses of the films based on PET are between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.
Bevorzugt sind die eingesetzten Folien nichttransparent. Sie können in beliebiger Art gefärbt, geschäumt oder ungeschäumt sein.The films used are preferably nontransparent. They can be dyed, foamed or unfoamed in any way.
Beispielsweise kann als Folie eine BOPP-Folie von EXXON eingesetzt werden, die 60 ZH 247 mit 60 µm Dicke, weiß und geschäumt.For example, the film can be a BOPP film from EXXON which is 60 ZH 247 with a thickness of 60 μm, white and foamed.
Der Träger und auch die Klebeschicht können transparent sein, und zwar dergestalt, dass jede Schicht vorzugsweise eine Transmission von größer 60 % aufweist, insbesondere eine Transmission größer 90 % bei einer Wellenlänge von 350 bis 1150 nm.The support and also the adhesive layer can be transparent, in such a way that each layer preferably has a transmission of greater than 60%, in particular a transmission greater than 90% at a wavelength of 350 to 1150 nm.
Mit dem Transmissionsgrad - bisweilen auch nur kurz als Transmission bezeichnet -, der in der Regel in % angegeben wird, ist das Verhältnis der auf der Rückseite eines mit Licht durchstrahlten Körpers ankommenden Lichtleistung zu der auf der Vorderseite eintreffenden Lichtleistung gemeint. Die Transmission wird beschnitten durch Reflektion und Absorption.
Die erfindungsgemäßen Etiketten können als Klebemassen eine Haftklebemasse auf Basis von Naturkautschuk, PUR, Acrylaten oder Styrol-Isopren-Styrol-Blockcolymeren enthalten. Eine Haftklebemasse ist eine viskoelastische Masse, die bei Raumtemperatur in trockenem Zustand permanent klebrig und klebfähig bleibt. Die Klebung erfolgt durch leichten Anpressdruck sofort auf fast allen Substraten.The labels according to the invention may contain, as adhesives, a pressure-sensitive adhesive based on natural rubber, PUR, acrylates or styrene-isoprene-styrene block copolymers. A pressure sensitive adhesive is a viscoelastic composition that remains permanently tacky and tacky at room temperature in a dry state. The bonding takes place by light pressure immediately on almost all substrates.
Geeignete Massen sind zum Beispiel im "
Als selbstklebende Masse kommt insbesondere eine handelsübliche druckempfindliche Klebmasse auf PUR, Acrylat- oder Kautschukbasis zum Einsatz, bevorzugt ein mit Additiven und Harzen abgemischter UV-vernetzbarer Arcylatschmelzhaftkleber. Beispielhaft sei die Klebemasse Novarad RC 21151 von Novamelt genannt.The self-adhesive composition used is in particular a commercially available pressure-sensitive adhesive composition based on PUR, acrylate or rubber, preferably a UV-crosslinkable hot-melt pressure-sensitive adhesive mixed with additives and resins. The Adhesive Novarad RC 21151 from Novamelt is an example.
Besonders vorteilhaft hat sich als Klebemasse eine solche auf Acrylathotmeltbasis erwiesen, die einen K-Wert von mindestens 20 aufweist, insbesondere größer 30, erhältlich durch Aufkonzentrieren einer Lösung einer solchen Masse zu einem als Hotmelt verarbeitbaren System.As an adhesive, it has proven particularly advantageous to use an acrylate hot melt base which has a K value of at least 20, in particular greater than 30, obtainable by concentrating a solution of such a composition into a system which can be processed as a hotmelt.
Eine derartige Klebemasse ist in der
In der Klebemasse auf Acrylathotmeltbasis können Benzoinderivate einpolymerisiert sein, so beispielsweise Benzoinacrylat oder Benzoinmethacrylat, Acrylsäure- oder Methacrylsäureester. Derartige Benzoinderivate sind in der
Eine Klebemasse, die sich als geeignet zeigt, ist eine niedermolekulare Acrylatschmelzhaftklebemasse, wie sie unter der Bezeichnung acResin UV oder Acronal ®, insbesondere Acronal DS 3458, von der BASF geführt wird. Diese Klebemasse mit niedrigem K-Wert erhält ihre anwendungsgerechten Eigenschaften durch eine abschließende strahlenchemisch ausgelöste Vernetzung.An adhesive which is suitable is a low molecular weight acrylate hot melt pressure-sensitive adhesive, such as that marketed under the name acResin UV or Acronal®, in particular Acronal DS 3458, by BASF. This adhesive with a low K value obtains its application-oriented properties through a final radiation-induced crosslinking.
Der Klebmasseauftrag liegt vorzugsweise zwischen 5,0 und 50,0 g/m2, weiter bevorzugt zwischen 10,0 und 30,0 g/m2 und besonders bevorzugt zwischen 15,0 und 25,0 g/m2. Letzteres entspricht einer Dicke zwischen 15 und 25 µm.The adhesive application is preferably between 5.0 and 50.0 g / m 2 , more preferably between 10.0 and 30.0 g / m 2 and particularly preferably between 15.0 and 25.0 g / m 2 . The latter corresponds to a thickness between 15 and 25 microns.
Vorzugsweise erfolgt der Auftrag der Klebemasse im Curtain-Coating-Verfahren.Preferably, the application of the adhesive takes place in the curtain coating process.
Als Trennfolie kann eine ein- oder beidseitig silikonisierte PET-Folie zum Einsatz kommen, vorzugsweise mit einer Dicke von 30 µm, beispielsweise die Silikonfolie Silphan S30 M74F von Siliconature.The release film used may be a PET film which is siliconized on one or both sides, preferably with a thickness of 30 .mu.m, for example the silicone film Silphan S30 M74F from Siliconature.
Es sind jedoch auch einseitig und beidseitig mit einer entsprechenden Trennschicht versehene Trägermaterialien aus Folienmaterialien wie PP oder Ähnlichem sowie Papier denkbar, jeweils mit einer bevorzugten Dicke zwischen 20,0 und 40,0 µm.However, it is also conceivable on one side and on both sides provided with a corresponding release layer support materials of film materials such as PP or the like and paper conceivable, each with a preferred thickness between 20.0 and 40.0 microns.
Die einzelnen Druckschichten und die Schutzlackschicht können in beliebigen Druckverfahren wie zum Beispiel (UV-)Flexo-, Offset- oder Siebdruck aufgebracht werden.The individual print layers and the protective lacquer layer can be applied in any printing process such as (UV) flexo, offset or screen printing.
Die erste, zweite und dritte Druckschicht können auch aus mehreren aufeinander gedruckten Lagen bestehen. Jede einzelne Lage weist vorzugsweise eine Dicke zwischen 1 und 2 µm auf, so dass sich die maximale Gesamtdicke der jeweiligen Druckschicht - sofern mehrere Lagen übereinander gedruckt sind - aus der Addition der Dicken der die Druckschicht bildende Lagen ergibt.The first, second and third printing layers can also consist of several successive printed layers. Each individual layer preferably has a thickness of between 1 and 2 .mu.m, so that the maximum total thickness of the respective print layer-if several layers are printed on one another-results from the addition of the thicknesses of the layers forming the print layer.
Die Dicken der einzelnen Schichten liegen bevorzugt innerhalb folgender Grenzen:
- erste Druckschicht zwischen 1 und 6 µm (bei bis zu drei Lagen)
- zweite Druckschicht zwischen 1 und 6 µm (bei bis zu drei Lagen)
Schutzlackschicht zwischen 2 und 3 µm- spaltfähige Druckschicht zwischen 3 und 4 µm

- cleavable printing layer between 3 and 4 microns
-
Adhesive layer 7 to 10 microns and / or - third print layer between 1 and 6 μm (up to three layers)
Für die drei Druckschichten werden vorzugsweise UV-härtende Flexodruckfarben gewählt, beispielsweise aus der Flint Serie UFZXXXXX der Firma Flint Group Switzerland AG. "XXXXX" verschlüsselt die Farbe, zum Beispiel UFZ50082 (Cyan), UFZ30082 (Magenta), UFZ10082 (Gelb), UFZ80082 (Schwarz).UV-curing flexographic printing inks are preferably selected for the three printing layers, for example from the Flint series UFZXXXXX from Flint Group Switzerland AG. "XXXXX" encrypts the color, for example, UFZ50082 (cyan), UFZ30082 (magenta), UFZ10082 (yellow), UFZ80082 (black).
Als Farbmittel in den UV-härtenden Flexodruckfarben finden organische Pigmente (ausgewählt in den Echtheiten nach Anforderung), basische Farbstoffe (hauptsächlich für Akzidenzdruck), Goldbronzen (Messing) und Silberbronzen (Aluminium), Perlglanzpigmente, Titandioxid, Ruße, Zapon-Farbstoffe® (Metallkomplexfarbstoffe) Verwendung.As coloring agents in the UV-curing flexographic printing inks, organic pigments (selected in the fastnesses as required), basic dyes (mainly for commercial printing), gold bronze (brass) and silver bronze (aluminum), pearlescent pigments, titanium dioxide, carbon blacks, zapon dyes ® (metal complex dyes ) Use.
Als Bindemittel werden Cellulose-Derivate wie Cellulosenitrat, Ethylcellulose, Ethylhydroxyethylcellulose oder Celluloseacetopropionat oder Vinylpolymerisate wie Polyvinylbutyrale, PVC-Mischpolymerisate, Polyacrylate und -methacrylate, Styrol-/Maleinsäure-Mischpolymerisate oder Polyamidharze oder Polyester oder Polyurethane, oder Ketonharze oder Maleinatharze oder Schellack eingesetzt.The binders used are cellulose derivatives such as cellulose nitrate, ethylcellulose, ethylhydroxyethylcellulose or cellulose acetopropionate or vinyl polymers such as polyvinyl butyrals, PVC copolymers, polyacrylates and methacrylates, styrene / maleic acid copolymers or polyamide resins or polyesters or polyurethanes, or ketone resins or maleate resins or shellac.
Für die Lösemittel werden Alkohole wie Ethanol, Propan-2-ol, Propan-1-ol Glycolether wie Methoxypropanol, Ethoxypropanol, Propylenglycol, Dipropylenglycolmonomethylether, Ester wie Ethylacetat, Isopropylacetat, Propylacetat, Methoxy- und Ethoxypropylacetat, Ketone für besondere Fälle wie Butan-2-on, 4-Methylpentan-2-on, Aceton, Cyclohexanon oder aliphatische Kohlenwasserstoffe wie Benzine, meistens in Verbindung mit Cosolvent-Polyamidharzen genutzt.For the solvents, alcohols such as ethanol, propan-2-ol, propan-1-ol are glycol ethers such as methoxypropanol, ethoxypropanol, propylene glycol, dipropylene glycol monomethyl ether, esters such as ethyl acetate, isopropyl acetate, propyl acetate, methoxy and ethoxypropyl acetate, ketones for special cases such as butane-2 -on, 4-methylpentan-2-one, acetone, cyclohexanone or aliphatic hydrocarbons such as gasolines, mostly used in conjunction with cosolvent polyamide resins.
Zur Optimierung werden Additive eingesetzt, beispielhaft seien Weichmacher, Wachse (Polyethylen- und Polypropylenwachse), Gleitmittel (Silicone, Fettsäureamide), Netzmittel oder Dispergiermittel erwähnt. Bei Wasserdruckfarben kommen zusätzlich Fungizide und Bakterizide zum Einsatz.For optimization purposes, additives are used, for example plasticizers, waxes (polyethylene and polypropylene waxes), lubricants (silicones, fatty acid amides), wetting agents or dispersants. In the case of water-based inks, fungicides and bactericides are also used.
Die erste Druckschicht gibt die Designwünsche des Kunden wieder. Die erste Druckschicht bildet das Bild, das der Kunde beim Blick auf das Etikett sieht. Der Aufdruck beziehungsweise die Wiedergabe des Designs ist in einer Druckmaschine in vielfacher Art umsetzbar.The first print layer reflects the customer's design wishes. The first print layer forms the image that the customer sees when looking at the label. The imprint or the reproduction of the design can be implemented in a printing press in many ways.
Die zweite Druckschicht wird - wie die dritte Druckschicht - erst nach Auftrennung des Etiketts sichtbar.The second print layer is - as the third print layer - visible only after separation of the label.
Alle drei Schichten werden vorzugsweise nach dem gleichen Verfahren unter Verwendung gleicher Druckfarben (mit gegebenenfalls unterschiedlichem Farbton) hergestellt.All three layers are preferably made by the same process using the same printing inks (optionally with different hue).
Der Aufdruck kann beispielsweise im Tiefdruckverfahren unter Verwendung von Lösemitteldruckfarben oder auch im Offsetdruckverfahren unter Verwendung entsprechender Offsetdruckfarben erfolgen. Farblieferanten sind neben der Flint Group Firmen wie Sun Chemical, Siegwerk oder Stehlin + Hostag.The printing can be done, for example, in gravure printing using solvent inks or offset printing process using appropriate offset inks. In addition to the Flint Group, paint suppliers include companies such as Sun Chemical, Siegwerk or Stehlin + Hostag.
Vorzugsweise wird das Flexodruckverfahren unter Verwendung von UV-härtenden Farbsystemen der UV-Farbserie "Flexocure Sigma" der Flint Group angewandt.Preferably, the flexographic printing process using UV-curable ink systems of the UV ink series "Flexocure Sigma" of the Flint Group is applied.
Im Flexodruckverfahren wird der Druckfarbenauftrag je Druckfarbe durch das Schöpfvolumen der verwendeten Rasterwalze bestimmt und liegt zwischen nominal 3,0 und 12,0 cm3 Druckfarbe je m2 Bedruckstoff.In the flexographic printing process, the ink application per ink is determined by the scoop volume of the anilox roller used and is between nominally 3.0 and 12.0 cm 3 of ink per m 2 of substrate.
Effektiv wird von dem Schöpfvolumen der Rasterwalze etwa ein Drittel des Farbvolumens auf den Bedruckstoff übertragen. Zur Farbgebung werden bevorzugt Rasterwalzen mit einem nominalen Schöpfvolumen zwischen 3,0 und 8,0 cm3/m2 eingesetzt. Noch weiter bevorzugte Rasterwalzen haben ein Schöpfvolumen zwischen 4,0 und 5,0 cm3/m2.Effectively, about one third of the ink volume is transferred to the substrate from the scoop volume of the anilox roller. For coloring, anilox rollers with a nominal scoop volume between 3.0 and 8.0 cm 3 / m 2 are preferably used. Still further preferred screen rollers have a cell volume between 4.0 and 5.0 cm 3 / m 2.
Für die Schutzlackschicht kann ebenfalls eine UV-härtende Flexofarbe wie eine solche aus der Flint Serie UFZXXXXX der Firma Flint Group Switzerland AG gewählt werden, beispielsweise UFZ00061 (transparent Weiß). Der effektive Farbauftrag liegt hier bevorzugt zwischen 1,0 und 4,0 cm3/m2, weiter vorzugsweise zwischen 2,0 und 3,0 cm3/m2.For the protective lacquer layer can also be a UV-curing flexo color such as those from the Flint series UFZXXXXX the company Flint Group Switzerland AG be selected, for example UFZ00061 (transparent white). The effective ink application is here preferably between 1.0 and 4.0 cm 3 / m 2 , more preferably between 2.0 and 3.0 cm 3 / m 2 .
Zur Sicherstellung der einwandfreien Funktionalität des Etiketts kann die auf Grund der Designvorgabe zum Teil nicht vollflächig gedruckte zweite Druckschicht mit einer gleichmässig homogenen, vollflächigen und bevorzugt transparenten Schutzlackschicht überdruckt werden. Dadurch werden störende Wechselwirkungen zwischen den verschiedenen Buntfarben aus der zweiten Druckschicht und der spaltfähigen Druckschicht unterbunden. Die Transparenz erfolgt aus dem Grund, den darunter befindlichen Druck (die zweite Druckschicht) gut lesbar zu erhalten.To ensure the proper functionality of the label, the printed on the basis of the design specification partly not fully printed second printing layer with a uniformly homogeneous, full-surface and preferably transparent protective lacquer layer can be overprinted. As a result, interfering interactions between the different colors from the second printing layer and the fissile print layer are prevented. The transparency is made for the reason that the underlying pressure (the second printing layer) is easy to read.
Das wesentliche Merkmal des Etiketts basiert auf dem Einsatz einer spaltfähigen Druckfarbe mit "trennenden" Eigenschaften. Verwendet werden können radikalisch oder kationisch UV-härtende Farbsysteme auf Silikonbasis.The essential feature of the label is based on the use of a splittable ink with "separating" properties. Radical or cationic UV-based silicone-based ink systems can be used.
Auch diese Schicht ist gemäß einer vorteilhaften Ausführungsform transparent. Bevorzugt wird ein wasserbasierendes Gemisch, bestehend aus einer wässrigen Flexofarbe wie Flint SOP00090, die darüber hinaus mit einem Verdicker (zum Beispiel HAW00104 der Flint Group Switzerland AG) sowie einem fluoreszierenden Rohstoff (zum Beispiel SQH00100 der Flint Group Switzerland AG) abgemischt ist.This layer is also transparent according to an advantageous embodiment. Preference is given to a water-based mixture consisting of an aqueous flexo ink such as Flint SOP00090, which is additionally blended with a thickener (for example HAW00104 from Flint Group Switzerland AG) and a fluorescent raw material (for example SQH00100 from Flint Group Switzerland AG).
Der Auftrag des wasserbasierenden Gemisches erfolgt ebenfalls im Flexodruckverfahren mit einem bevorzugten, effektiven Farbauftrag zwischen 1,0 und 8,0 cm3/m2 und einem besonders bevorzugten Auftragsvolumen zwischen 3,0 und 4,0 cm3/m2.The order of the water-based mixture also takes place in the flexographic printing process with a preferred, effective ink application between 1.0 and 8.0 cm 3 / m 2 and a particularly preferred order volume between 3.0 and 4.0 cm 3 / m 2 .
Um einem Entmischen oder Aufkonzentrieren der einzelnen Komponenten im Trennlack entgegenzuwirken, sollte das Trennlackgemisch bei der Verarbeitung ständig gerührt werden. Die Trocknung des wässrigen Trennlackes erfolgt thermisch bei Trocknungstemperaturen zwischen 40 bis 100 °C, bevorzugt 60 bis 80 °C.To counteract segregation or concentration of the individual components in the release coating, the release coating mixture should be constantly stirred during processing. The drying of the aqueous release coating is carried out thermally at drying temperatures between 40 to 100 ° C, preferably 60 to 80 ° C.
Sämtliche der für die Trennlackierung verwendeten Rohstoffe stammen vorzugsweise von der Firma Flint Group Switzerland AG.All of the raw materials used for the release coating are preferably from the company Flint Group Switzerland AG.
Das Gemisch besteht gemäß einer vorteilhaften Ausführungsform der Erfindung aus 80,0 bis 98,0 Gew.-% einer UV-härtenden Flexodruckfarbe wie zum Beispiel "SOP00090", 1,0 bis 8,0 Gew.-% eines Verdickers wie zum Beispiel "HAW00104" und 1,0 bis 12,0 Gew.-% eines fluoreszierenden Zusatzes wie zum Beispiel "SOH00100", besonders bevorzugt aus 90,0 bis 95,0 Gew.-% der Flexodruckfarbe, 2,0 bis 4,0 Gew.-% des Verdickers und 3,0 bis 6,0 Gew.-% des fluoreszierenden Zusatzes.According to an advantageous embodiment of the invention, the mixture consists of 80.0 to 98.0% by weight of a UV-curing flexographic ink such as "SOP00090", 1.0 to 8.0% by weight of a thickener such as, for example " HAW00104 "and 1.0 to 12.0 wt .-% of a fluorescent additive such as" SOH00100 ", more preferably from 90.0 to 95.0 wt .-% of the flexographic ink, 2.0 to 4.0 wt. -% of the thickener and 3.0 to 6.0 wt .-% of the fluorescent additive.
Ein Verdicker wie "HAW00104" erhöht die Viskosität des wässrigen Farbsystems. Insbesondere wässrige Farbsysteme neigen auch auf sorgfältig physikalisch vorbehandelten (Polyolefin)folien zum Zusammenfliessen, das heißt, dass die Farbe von einigen Bereichen auf der Folie abgestossen wird und in anderen Bereichen zusammenfließt. Durch dieses Zusammenfliessen bilden sich nach dem Aufbringen der Druckfarbe auf dem Bedruckstoff so genannte "pinholes", die Farbe liegt nicht in einem homogenen, zusammenhängenden Film vor. Die Farbe "liegt unruhig" (Mottling).A thickener like "HAW00104" increases the viscosity of the aqueous paint system. In particular, aqueous ink systems also tend to coalesce on carefully physically pretreated (polyolefin) films, that is, the paint is repelled from some areas of the film and coalesces in other areas. As a result of this confluence, so-called "pinholes" form on the printing substrate after the application of the printing ink; the ink is not present in a homogeneous, coherent film. The color "is restless" (mottling).
Durch die Erhöhung der Viskosität wird das Mottling unterdrückt. Dies hat zur Folge, dass sich beim Druckvorgang der Farbtransfer erhöht und dass sich die Entleerung der Rasterwalze verbessert.Increasing the viscosity suppresses mottling. As a result, the color transfer increases during the printing process and the emptying of the anilox roller improves.
Um den transparenten Trennlack passgenau auf das Etikett aufdrucken zu können, wird dem Trennlackgemisch ein fluoreszierender Rohstoff wie "SQH00100" zugegeben. Dadurch hat der Maschinenführer die Möglichkeit, unter Verwendung einer Schwarzlichtlampe die Passgenauigkeit der Trennlackierung zu kontrollieren und gegebenenfalls nachzujustieren.In order to be able to print the transparent release lacquer precisely on the label, a fluorescent raw material such as "SQH00100" is added to the release lacquer mixture. As a result, the machine operator has the ability to control using a black light lamp, the accuracy of fit of the release coating and readjust if necessary.
Die Klebemassenabdeckschicht dient zur perfekten Neutralisation der Klebmasse nach Auftrennung des Etiketts. Beim Abziehen des aufgeklebten Etiketts von einem Substrat trennt sich das Etikett an der spaltfähigen Druckschicht, das heißt, ein Teil der spaltfähigen Druckschicht verbleibt am oberen Teil des Etiketts, ein Teil am unteren Teil. Da die dritte Druckschicht zumeist partiell aufgebracht ist und auch die spaltfähige Druckschicht gegebenenfalls sich derart trennt, dass diese nur partiell am unteren Teil des Etiketts verbleibt, besteht die Gefahr, dass die Klebemassenschicht nicht vollständig abgedeckt ist und somit zumindest abschnittsweise weiterhin klebrig ist, was eher unerwünscht ist.The Klebemassenabdeckschicht serves for perfect neutralization of the adhesive after separation of the label. When the adhered label is peeled from a substrate, the label separates at the splittable printing layer, that is, a part of the splittable printing layer remains at the upper part of the label, a part at the lower part. Since the third printing layer is usually applied partially and the splittable printing layer optionally separates so that it remains only partially at the bottom of the label, there is a risk that the adhesive layer is not completely covered and thus at least partially still sticky, which is more likely is undesirable.
Durch den vollflächigen Auftrag der Klebemassenabdeckschicht ist gewährleistet, dass die Klebemasse vollständige bedeckt und somit neutralisiert ist, so dass nach dem Abziehen des Etiketts die auf dem Substrat verbleibende Klebmasse keine haftklebrige Eigenschaften zeigt.The full-surface application of the Klebemassenabdeckschicht ensures that the adhesive is completely covered and thus neutralized, so that after the Peel off the label, the remaining adhesive on the substrate shows no sticky properties.
Um die Klebmasse vollständig zu neutralisieren, kommt als Neutralisationsbedruckung eine Druckfarbe für besonders hohen Farbauftrag zum Einsatz. Bevorzugt erfolgt der Farbauftrag im Siebdruckverfahren. Zum Übertragen der Farbe kommen bevorzugt RSS-Siebe (Plattendicke 66 µm, Maschenzahl 290 Maschen/Zoll, Offene Siebfläche 21 %, Maschenweite 40 µm, Farbschichtstärke 10 µm, Auflösung Strichbreite 150 µm) von der Firma Gallus zum Einsatz, welche eine Farbschichtdicke von 10 µm übertragen. Als besonders geeignet haben sich HM-Siebe (Plattendicke 57 µm, Maschenzahl 275 Maschen/Zoll, Offene Siebfläche 21 %, Maschenweite 40 µm, Farbschichtstärke 7 µm, Auflösung Strichbreite 130 µm) der Firma Gallus mit einer farbübertragenden Schichtdicke von 7 µm herausgestellt.In order to completely neutralize the adhesive, a printing ink for particularly high paint application is used as neutralization printing. Preferably, the paint is applied by screen printing. For transferring the color preferably RSS screens (plate thickness 66 microns, mesh 290 mesh / inch, 21% open mesh area, mesh size 40 microns,
Info zu den Sieben: siehe AnlagenInformation about the sieves: see attachments
Bevorzugt wird eine transparent weisse, UV-härtende Siebdruckfarbe, zum Beispiel aus der Farbserie "Uvoscreen II" mit der Bezeichnung "USC00061" von der Firma der Flint Group Switzerland AG.Preference is given to a transparent white, UV-curing screen printing ink, for example from the "Uvoscreen II" ink series with the designation "USC00061" from the company of Flint Group Switzerland AG.
Insbesondere für Anwendungen im Lebensmittelbereich hat sich als bevorzugt eine Farbmischung aus einer UV-härtenden transparent weissen Flexofarbe der UV-Farbserie "Flexocure Gemini" mit der Bezeichnung "UFG00061" von der Firma der Flint Group Switzerland AG herausgestellt.In particular, for applications in the food industry, a color mixture of a UV-curable transparent white flexo ink of the UV color series "Flexocure Gemini" with the name "UFG00061" by Flint Group Switzerland AG has proven to be preferred.
Um diese UV-Flexofarbe im Siebdruckverfahren verarbeiten zu können, ist das Abmischen der Farbe mit 0,5 bis 3,0 Gew.-%, besonders bevorzugt 1,0 bis 2,0 Gew.-% eines silikonbasiertem Verlaufsmittels wie zum Beispiel dem Rohstoff "UAS00100" der Flint Group Switzerland AG notwendig.In order to be able to process this UV flexo ink by screen printing, the mixing of the ink with 0.5 to 3.0 wt .-%, particularly preferably 1.0 to 2.0 wt .-% of a silicone-based leveling agent such as the raw material "UAS00100" of the Flint Group Switzerland AG necessary.
Wie bei dem Verdrucken der spaltfähigen Druckschicht ist auch beim Verdrucken der Klebemassenabdeckschicht die passgenaue Bedruckung des Etiketts von entscheidender Bedeutung. Um die abgemischte, transparent weisse UV-Flexofarbe unter Schwarzlicht sichtbar machen zu können, wird die Farbe zusätzlich mit 0,5 bis 3,0 Gew.-%, besonders bevorzugt 1,0 bis 2,0 Gew.-% mit einem für UV-Druckfarben geeigneten fluoreszierenden Rohstoff wie "UAA00105" der Flint Group Switzerland AG abgemischt.As with the printing of the splittable printing layer, the accurate printing of the label is also of crucial importance when printing the adhesive compound covering layer. In order to make visible the blended, transparent white UV flexo under black light, the color is additionally 0.5 to 3.0 wt .-%, particularly preferably 1.0 to 2.0 wt .-% with a UV Blended suitable fluorescent raw material such as "UAA00105" of Flint Group Switzerland AG.
Um fälschungssichere Aspekte in den zur Verwendung kommenden Etiketten zu berücksichtigen, können zusätzlich unterschiedliche Farbpigmente und -stoffe in den Druckfarben zum Einsatz kommen.In order to take counterfeit-proof aspects into account in the labels used, it is additionally possible to use different color pigments and substances in the printing inks.
Am weitesten verbreitet sind langnachleuchtende (phosphorizierende) oder fluoreszierende Pigmente, die nur oder überwiegend durch UV-Strahlung angeregt werden und im sichtbaren Bereich des Spektrums emittieren (als Übersicht siehe zum Beispiel
Bekannt sind aber auch IR-aktive Leuchtpigmente. Beispiele für Systeme mit UV-Fluoreszenz sind Xanthene, Cumarine, Naphthalimide usw., die teilweise unter dem Oberbegriff "organische Leuchtstoffe" oder "optische Aufheller" in der Literatur geführt werden. Die Zugabe von einigen Prozenten der betreffenden Leuchtstoffe ist ausreichend.However, IR-active luminescent pigments are also known. Examples of systems with UV fluorescence are xanthenes, coumarins, naphthalimides, etc., which are sometimes referred to in the literature under the generic term "organic phosphors" or "optical brighteners". The addition of a few percent of the relevant phosphors is sufficient.
Eingesetzt werden können beispielsweise Rezepturen mit RADGLO®-Pigmenten der Firma Radiant Color N.V./Holland oder Lumilux® CD-Pigmente von Firma Riedel-de-Haen. Auch anorganische Leuchtstoffe sind geeignet. Als langnachleuchtende Stoffe, besonders mit Emission von Licht im gelben Bereich, haben sich Metallsulfide und -oxide, meist in Verbindung mit geeigneten Aktivatoren, als günstig erwiesen. Diese sind beispielsweise unter dem Handelsnamen Lumilux® N oder als bezüglich Stabilität, Leuchtkraft und Nachleuchtdauer verbesserte Leuchtpigmente unter dem Handelsnamen LumiNova® von Firma Nemoto/Japan erhältlich.For example, formulations with RADGLO® pigments from Radiant Color N.V./Holland or Lumilux® CD pigments from Riedel-de-Haen can be used. Also inorganic phosphors are suitable. As photoluminescent substances, especially with the emission of light in the yellow range, metal sulfides and oxides, usually in combination with suitable activators, have proved favorable. These are available, for example, under the trade name Lumilux® N or as luminescent pigments improved in terms of stability, luminosity and persistence under the trade name LumiNova® from Nemoto / Japan.
Prinzipiell geeignet sind auch Leuchtstoffe, die durch Elektronenstrahlen oder Röntgenstrahlen angeregt werden sowie thermochrome Pigmente, die sich bei Temperaturänderung reversibel umfärben. Auch die Verwendung von elektrisch leitfähigen Farben ist möglich.Also suitable in principle are phosphors which are excited by electron beams or X-rays and thermochromic pigments which reversibly change color when the temperature changes. The use of electrically conductive colors is possible.
Bei der Auswahl der Farbpigmente ist darauf zu achten, dass sie für den Herstellprozess des Etiketts (zum Beispiel Kleberbeschichtung) ausreichend stabil sind und sich nicht irreversibel bei den Prozessbedingungen (gegebenenfalls thermische Trocknung, Elektronenstrahl- oder UV-Härtung) verändern.When selecting the color pigments, care must be taken that they are sufficiently stable for the production process of the label (for example adhesive coating) and do not change irreversibly in the process conditions (optionally thermal drying, electron beam or UV curing).
Das erfindungsgemäße Etikett vereinigt viele Vorteile in sich.The label according to the invention combines many advantages.
Das Etikett bietet die neuartige Möglichkeit, trotz eines einlagigen Trägermaterials dem Kunden ein Etikett zur Verfügung zu stellen, bei denen bis zu drei Seiten mit einem individuellen Text oder Ähnlichem versehen werden können.The label offers the novel possibility of providing the customer with a label in which up to three pages can be provided with an individual text or the like, despite a single-layer carrier material.
Der spezielle Produktaufbau ermöglicht es, dass die beiden Seiten des Trägermaterials (Bedruckstoff) mit kundenindividuellen Informationen bedruckt werden. Vorteilhaft und neu ist, dass zusätzliche Informationen zwischen der spaltfähigen Schicht und der Klebemasse in Form der dritten Schicht aufgebracht werden können.The special product structure enables the two sides of the carrier material (substrate) to be printed with customized information. It is advantageous and novel that additional information can be applied between the splittable layer and the adhesive in the form of the third layer.
Als Trägermaterial für diese zusätzlichen Informationen ist kein weiter Bedruckstoff in Form einer Folie oder Ähnlichem erforderlich. Im Prinzip fungiert das Substrat, auf das das Etikett aufgeklebt wird, als Träger für die darauf mit der zusätzlichen Information verbleibenden Klebmasse.As a carrier material for this additional information no further substrate in the form of a film or the like is required. In principle, the substrate to which the label is adhered acts as a carrier for the adhesive remaining thereon with the additional information.
Da das Etikett aus nur einer Träger-, vorzugsweise Folienschicht, einer Klebmasseschicht und diversen Druckschichten besteht, ist die Materialdicke im Vergleich zu den klassischen Etiketten deutlich dünner. Durch diesen Vorteil lässt sich das Etikettenmaterial mit den klassischen Etikettiermaschinen sehr viel einfacher und störungsfrei verarbeiten.Since the label consists of only one carrier layer, preferably a film layer, an adhesive layer and various print layers, the material thickness is significantly thinner compared to the conventional labels. This advantage makes it much easier and trouble-free to process the label material with the classic labeling machines.
Beim bekannten Etikett ist gewünscht, dass das auf dem Substrat (Untergrund) aufgebrachte Etikett rückstandsfrei und ohne haftklebrige Eigenschaften entfernt werden kann. Um diese Eigenschaft zu erzielen, wird bei einem klassischen Etikett der Träger üblicherweise mit einem Selbstklebematerial in einen reversiblen Verbund gebracht. Dadurch liegt ein verhältnismäßig steifes und unter Umständen schwierig zu verarbeitendes Material vor.In the case of the known label, it is desired that the label applied to the substrate (background) can be removed without residue and without pressure-sensitive adhesive properties. In order to achieve this property, in a conventional label the carrier is usually placed in a reversible composite with a self-adhesive material. This results in a relatively stiff and possibly difficult to process material.
Das neue Etikett besteht im Vergleich zum klassischen Etikett aus lediglich einer Trägerschicht (üblicherweise weiß, geschäumte BOPP-Folie), auf welcher direkt und reversibel die Klebmasse aufgebracht ist.Compared to the classic label, the new label consists of only one carrier layer (usually white, foamed BOPP film) on which the adhesive is directly and reversibly applied.
Die Verwendung eines zusätzlichen Trägermaterials in Form eines Selbstklebematerials entfällt, wodurch das einlagige Etikett deutlich dünner ist als ein klassisches Etikett.The use of an additional carrier material in the form of a self-adhesive material is eliminated, making the single-layer label significantly thinner than a classic label.
Besonders optimal lässt sich das Etikett auf Verpackungen aus Pappe oder Folie verwenden.The label can be optimally used on cardboard or foil packaging.
Anhand der nachfolgend beschriebenen Figuren wird ein Etikett in einer besonders vorteilhaften Ausführung näher erläutert, ohne damit die Erfindung unnötig einschränken zu wollen.With reference to the figures described below, a label is explained in more detail in a particularly advantageous embodiment, without thereby wanting to limit the invention unnecessarily.
