Description

GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung betrifft ein Verfahren zum Bedrucken von Folien sowie eine dadurch hergestellter Folienverbund.The present invention relates to a process for printing on films and a film composite produced thereby.

HINTERGRUND DER ERFINDUNGBACKGROUND OF THE INVENTION

Folien kommen in der Verpackungsindustrie zum Einsatz, wobei hier sowohl Monofolien als auch Verbundfolien Verwendung finden.Films are used in the packaging industry, with both monofilms and composite films being used here.

Die verwendeten Folien werden dabei bedruckt, um dem Verbraucher Informationen über das Produkt, den Hersteller oder die Marke zu vermitteln und eine ästhetische Anmutung zu erzeugen. Neben den bisher gängigen Druckverfahren wie beispielsweise Tiefdruck gewinnt dabei der Digitaldruck zunehmend an Bedeutung und wird beispielsweise bei Etiketten, Papier-Anwendungen oder sogenannten Shrink-Sleeves bereits eingesetzt.The films used are printed to give the consumer information about the product, the manufacturer or the brand and to create an aesthetic appearance. In addition to the previously common printing processes such as gravure digital printing is becoming increasingly important and is already used for example in labels, paper applications or so-called shrink sleeves.

Bei Folien, insbesondere Verbundfolien, die siegelfähig sind und im Rahmen des Verpackungsprozesses dann auch versiegelt werden, bestehen jedoch besondere Anforderungen an mechanische und thermische Beständigkeiten des Druckbildes, die mit herkömmlichen Digitaldruckverfahren und -vorrichtungen nicht erzielt werden kann.For films, in particular composite films which are sealable and then sealed in the packaging process, however, there are special requirements for mechanical and thermal resistances of the printed image, which can not be achieved with conventional digital printing methods and devices.

Klassisch werden derartige Folien typischerweise bisher im Tief- oder Flexodruckverfahren bedruckt, das jedoch sehr aufwendig ist.Classically, such films are typically previously printed in gravure or flexographic printing, which is very expensive.

Eine Verwendung des Digitaldruckverfahrens ist bisher nur möglich, wenn bei Verbundfolien die Bedruckung auf der Innenseite des Druckträgers erfolgt. Dies macht dann jedoch weitere Produktionsvorgänge wie Kaschieren, Aushärten, etc. erforderlich.A use of the digital printing method is so far only possible if the composite printing on the inside of the print carrier takes place. However, this then requires further production operations such as lamination, curing, etc.

In DE 10 2009 043042 A1 wird ein Verfahren zur Herstellung bedruckter Verpackungen aus kaschiertem Folienmaterial sowie ein bedrucktes kaschiertes Folienmaterial vorgeschlagen. Bei dem Verfahren wird eine transparente Druckträgerfolie mit einer ersten Primerschicht versehen und die Primerschicht digital bedruckt. Die hierdurch gegebene Farbschicht wird mit einer weiteren Primerschicht abgedeckt, bevor eine Abdeckfolie mittels eines nach dem Aushärten elastomeren 2K-PUKlebers aufgebracht wird.In DE 10 2009 043042 A1 a method for the production of printed packaging made of laminated film material and a printed laminated film material is proposed. In the method, a transparent print carrier film is provided with a first primer layer and the primer layer is digitally printed. The color layer given thereby is covered with a further primer layer, before a covering film is applied by means of a 2K PU adhesive which is elastomeric after curing.

Wünschenswert wäre es daher, ein Verfahren zu schaffen, das in der Lage ist, Folien, insbesondere Verbundfolien, im Aussendruck zu bedrucken und dabei ein Digitaldruckverfahren zu verwenden.It would therefore be desirable to provide a method which is capable of printing on films, in particular composite films, in the external printing and thereby to use a digital printing process.

Digitaldruck für die Bedruckung von Folien ist grundsätzlich bereits bekannt. So wird beispielsweise von Hewlett Packard unter der Bezeichnung Indigo eine Digitaldruckmaschine angeboten, die grundsätzlich auch zum Bedrucken von Folien geeignet ist. Bei dieser Maschine wird die Druckseite zunächst Corona-vorbehandelt, dann ein auf wässriger Lösung basierender Primer aufgetragen und schließlich erfolgt die Bedruckung der Folie im Digitaldruck.Digital printing for the printing of foils is basically already known. For example, Hewlett Packard offers a digital printing machine called Indigo, which is basically also suitable for printing on film. In this machine, the print side is first corona-pretreated, then applied to an aqueous solution based primer and finally the printing of the film is done in digital printing.

Die derart bedruckten Folien weisen jedoch nicht die erforderliche thermische und mechanische Beständigkeit auf, die von siegelfähigen Folien erwartet wird.However, the films so printed do not have the required thermal and mechanical resistance expected from sealable films.

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verfahren zu schaffen, das einen Digitaldruck mit verbesserter thermischer und mechanischer Stabilität ermöglicht, der auch bei siegelfähigen Folien eingesetzt werden kann.It is therefore an object of the present invention to provide a method which enables digital printing with improved thermal and mechanical stability, which can also be used in sealable films.

ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Gemäß einem Ausführungsbeispiel umfasst die Erfindung ein Verfahren zum digitalen Bedrucken eines Folienverbunds oder einer Folie, aufweisend folgende Schritte:

  • Performing a corona pretreatment of the primed film composite or film;
  • Printing the corona-pretreated, primed film composite or film in a digital printing process;

Die Coronavorbehandlung vor dem Primern und vor dem Bedrucken führt zu einer besonders hohen mechanischen und thermischen Stabilität der bedruckten Folie.The corona pre-treatment before priming and before printing leads to a particularly high mechanical and thermal stability of the printed film.

Gemäß einem Ausführungsbeispiel umfasst das Verfahren:

  • Durchführen einer Coronavorbehandlung des bedruckten, coronavorbehandelten, geprimerten Folienverbunds oder der Folie vor dem Auftragen des Schutzlacks.
According to one embodiment, the method comprises:

Durch das erneute Coronavorbehandeln wird die Stabilität zusätzlich erhöht.The re-Coronavorbehandeln the stability is additionally increased.

Gemäß einem Ausführungsbeispiel ist Primer ein auf einem organischen Lösemittel basierter Primer.In one embodiment, primer is an organic solvent-based primer.

Dies erhöht weiter die Stabilität der bedruckten Folie.This further increases the stability of the printed film.

Gemäß einem Ausführungsbeispiel ist der Primer ein Zwei-Komponenten-Primer.According to one embodiment, the primer is a two-component primer.

Dies ist eine besonders vorteilhafte Ausgestaltung des Primers.This is a particularly advantageous embodiment of the primer.

Gemäß einem weiteren bevorzugten Ausführungsbeispiel kann der Primer auch ein 1 Komponenten-Primer auf Basis Polyurethan oder Polyvinylbutyral (PVB) sein.According to another preferred embodiment, the primer may also be a 1-component primer based on polyurethane or polyvinyl butyral (PVB).

Gemäß einem Ausführungsbeispiel wird der Primer mit einer Dicke von 0,1 bis 1 g/m2 aufgetragen.According to one embodiment, the primer is applied at a thickness of 0.1 to 1 g / m 2.

Dies ist eine vergleichsweise dünne Primer.-Schicht, die jedoch dank der Coronavorbehandlung ausreicht, um eine hinreichende Stabilität des Druckbildes zu erzielen.This is a comparatively thin primer layer, which, however, thanks to the corona pretreatment, is sufficient to achieve sufficient stability of the printed image.

Gemäß einem Ausführungsbeispiel wird der Schutzlack mit einer Dicke von 0,3 bis 2 g/m2 aufgetragen wird.In one embodiment, the resist is applied at a thickness of 0.3 to 2 g / m 2.

Gemäß einem Ausführungsbeispiel wird als Schutzlack ein strahlenhärtender Schutzlack verwendet, wobei
der Schutzlack mittels elektrobeam-Härtung gehärtet wird, oder
der Schutzlack mittels UV-Härtung gehärtet wird.According to one embodiment, a radiation-curing protective lacquer is used as a protective lacquer, wherein

Fig. 1 illustriert schematisch ein Verfahren gemäß einem Ausführungsbeispiel der Erfindung. Fig. 1 schematically illustrates a method according to an embodiment of the invention.

DETAILLIERTE BESCHREIBUNGDETAILED DESCRIPTION

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen im Detail beschrieben.The invention will be described in detail below with reference to exemplary embodiments.

Die Ausführungsbeispiele ermöglichen dabei die Bedruckung bahnförmiger Verbunde (Mehrschicht-Laminate) oder Folien für flexible Verpackungen von Lebensmittel-, Non Food-, Pet Food-, Pharma- oder Medical - Anwendungen.The embodiments allow the printing of web-like composites (multilayer laminates) or films for flexible packaging of food, non-food, pet food, pharmaceutical or medical applications.

Diese Verbunde bestehen im Allgemeinen aus mindestens 2 verschiedenen Folien, die Kunststofffolien, und / oder Metallfolien, und / oder Papierfolien enthalten. Gemäß einem Ausführungsbeispiel kann es sich aber auch um Monofolien handeln.These composites generally consist of at least 2 different films containing plastic films, and / or metal foils, and / or paper foils. According to one embodiment, it may also be monofilm.

Die Druckseite dieses Verbunds (Mehrschicht-Laminat) oder der Folie wird zur Erzielung einer besseren Primerhaftung auf der Druckseite zunächst mit einer Corona-Vorbehandlung bearbeitet, die gemäß einem Ausführungsbeispiel inline erfolgt. Bei einer Coronavorbehandlung wird die zu behandelnde Oberfläche für eine kurze Zeit einer elektrischen Coronaentladung ausgesetzt. Dabei kann eine handelsübliche Vorrichtung zur Coronavorbehandlung zum Einsatz kommen.The pressure side of this composite (multilayer laminate) or the film is first processed to achieve a better primer adhesion on the pressure side with a corona pretreatment, which takes place according to an embodiment inline. In a corona pretreatment, the surface to be treated is exposed to an electric corona discharge for a short time. In this case, a commercially available device for corona treatment can be used.

Diese Vorbehandlung dient dazu, die Oberfläche des Druckträger von Materialien zu reinigen, welche durch Abklatsch (Set off) von der Siegelseite oder Migration an der Oberfläche angelagert wurden. Daneben entstehen dadurch an der Oberfläche polare Moleküle, an die sich dann der Primer besser anbinden kann.This pre-treatment serves to clean the surface of the print substrate of materials which have been deposited by set-off from the seal side or migration to the surface. In addition, polar molecules are formed on the surface, to which the primer can then better bind.

Im Anschluss an die Corona-Vorbehandlung wird gemäß einem Ausführungsbeispiel auf der Druckseite dieses Verbunds (Mehrschicht-Laminat) oder der Folie zur Erzielung einer besseren Farbhaftung auf der Druckseite zunächst ein Primer oder Haftvermittler aufgetragen. Der Auftrag erfolgt dabei gemäß einem Ausführungsbeispiel von 0.1 bis 1 g/m2 trocken.Following the corona pretreatment, a primer or adhesion promoter is first applied to the printing side of this composite (multilayer laminate) or the film to achieve a better ink adhesion on the printing side according to an embodiment. The order takes place according to an embodiment of 0.1 to 1 g / m2 dry.

Gemäß einem Ausführungsbeispiel wird dabei ein lösemittelhaltiger Primer verwendet, bzw. ein Primer auf Basis eines organischen Lösungsmittels. Mit auf einem organischen Lösemittel basierenden Primern erreicht man gegenüber den im herkömmlichen Digitaldruck eingesetzten Primern, die auf wässriger Lösung basieren, eine erhöhte mechanische und thermische Stabilität des bedruckten Endproduktes.According to one embodiment, a solvent-containing primer is used, or a primer based on an organic solvent. With primers based on an organic solvent, an increased mechanical and thermal stability of the printed end product is achieved compared to the primers used in conventional digital printing, which are based on aqueous solution.

Gemäß einem Ausführungsbeispiel handelt es sich dabei bei dem auf einem organischen Lösemittel basierenden Primer um einen Zwei-Komponenten-Primer.In one embodiment, the primer based on an organic solvent is a two-component primer.

Die beiden Komponenten können gemäß einem Ausführungsbeispiel beispielsweise ein Zwei-Komponenten Primer auf Basis Polyurethan und Isocyanat sein. Damit lässt sich dann eine gute mechanische und thermische Stabilität erzielen.The two components can be, for example, a two-component primer based on polyurethane and isocyanate according to one embodiment. This can then achieve a good mechanical and thermal stability.

Der Auftrag des lösemittelhaltigen Primers erfolgt gemäß einem Ausführungsbeispiel auf einer separaten Anlage und nicht auf der Digitaldruckanlage. Dadurch wird die Verwendung eines lösemittelbasierten Primers ermöglicht, die wegen des fehlenden Explosionsschutzes bei herkömmlichen Digitaldruckanlagen nicht möglich ist.The order of the solvent-based primer is carried out according to an embodiment on a separate system and not on the digital printing system. This allows the use of a solvent-based primer, which is not possible due to the lack of explosion protection in conventional digital printing systems.

Die in einer separaten Anlage geprimerte Rolle kann dann möglicherweise unterschiedlich lange liegen, bis die Bedruckung erfolgt. Aufgrund der unterschiedliche langen Liegezeit dieser geprimerten Rolle, die von einem Tag bis mehrere Monate, ausnahmsweise bis zu max. 2 Jahren, reichen kann, ist der Abklatsch (Set off) oder die Migration unterschiedlich groß. Dies kann dann dazu führen, dass bei dem direkten Farbauftrag auf den Primer, wie es bei herkömmlichen Druckverfahren vorgesehen ist, eine nur geringe Stabilität des Druckbildes erzielt wird.The roller primed in a separate unit may then be of different lengths until printing takes place. Due to the different long lying time of this primed role, which varies from one day to several months, exceptionally up to max. 2 years, the gossip (set off) or the migration varies in size. This can then lead to only a slight stability of the print image being achieved in the case of the direct application of ink to the primer, as provided in conventional printing processes.

Gemäß einem Ausführungsbeispiel erfolgt dann der Digitaldruck auf dem vorgeprimerten Verbund (Mehrschicht-Laminat) oder der Folie, wobei jedoch - vorzugsweise inline - vor dem Druck die geprimerte Seite des Verbunds (Mehrschicht-Laminat) oder der Folie über eine Corona-Vorbehandlung bearbeitet wird.According to one embodiment, the digital printing then takes place on the pre-primed composite (multilayer laminate) or the film, but - preferably inline - before printing the primed side of the composite (multilayer laminate) or the film is processed via a corona pretreatment.

Diese Vorbehandlung dient dazu, die Oberfläche der (dünnen) Primerschicht (005) von Materialien zu reinigen, welche durch Abklatsch oder Migration an Oberfläche angelagert wurden. Dabei erfolgt gemäß einem Ausführungsbeispiel die Corona-Vorbehandlung aufgrund der vergleichsweise dünnen Primerschicht, die eine Dicke von vorzugsweise 0,1 bis 1 g/m2 aufweist, in ihrer Corona-Stärke entsprechend.This pre-treatment serves to clean the surface of the (thin) primer layer (005) of materials which have been deposited by imprinting or migration on the surface. In this case, according to one exemplary embodiment, the corona pretreatment takes place in accordance with its corona strength owing to the comparatively thin primer layer, which has a thickness of preferably 0.1 to 1 g / m.sup.2.

Die Corona-Stärke liegt dabei gemäß einem Ausführungsbeispiel in einem Bereich von 3 bis 20 W min / m2.The corona strength is according to one embodiment in a range of 3 to 20 W min / m2.

Der Digitaldruck erfolgt dann auf diese Corona-vorbehandelte Seite (006) des Primers.The digital printing then takes place on this corona-pretreated side (006) of the primer.

Gemäß einem Ausführungsbeispiel wird dann für die tatsächliche Anwendung des Verbund (Mehrschicht-Laminat) oder der Folie eine Schutzlackierung gegen physikalische, thermische oder chemische Einflüsse aufgebracht. Hierzu erfolgt auf den digital-bedruckten Verbund (Mehrschicht-Laminat) oder der Folie eine Schutzlackierung. Die Auftragsmenge dieses Schutzlacks beträgt gemäß einem Ausführungsbeispiel 0.3 bis 2 g / m2 trocken. Die Auftragsmenge des Schutzlacks kann dabei je nach Anwendung der Folie/des Verbunds und der Farbauftragsmenge variieren. Vorzugsweise wird bei höherer Farbauftragsmenge auch eine größere Menge Schutzlack aufgetragen..According to one embodiment, a protective coating against physical, thermal or chemical influences is then applied for the actual application of the composite (multilayer laminate) or the film. For this purpose, a protective coating is applied to the digitally printed composite (multilayer laminate) or the film. The application rate of this protective coating is according to one embodiment 0.3 to 2 g / m 2 dry. The amount applied to the protective varnish may vary depending on the application of the film / composite and the amount of ink application. Preferably, a larger amount of protective lacquer is applied at a higher paint application.

Die Digital-bedruckte Seite des Verbunds (Mehrschicht-Laminat) oder der Folie wird gemäß eines Ausführungsbeispiels zur Erzielung einer besseren Schutzlackhaftung auf der digital-bedruckten Seite - vorzugsweise inline - vor dem Schutzlack-Auftrag mit einer Corona-Vorbehandlung bearbeitet.The digital-printed side of the composite (multilayer laminate) or film is processed in accordance with an embodiment to achieve a better resist adhesion on the digital-printed side - preferably inline - before the protective coating application with a corona pretreatment.

Diese Vorbehandlung dient dazu, die Oberfläche der digital-bedruckten Seite des Verbunds (Mehrschicht-Laminat) oder der Folie zu reinigen, welche durch Abklatsch (Set off) oder Migration an Oberfläche angelagert wurden.This pretreatment is to clean the surface of the digital-printed side of the composite (multilayer laminate) or film which has been deposited by set-off or migration to surface.

Dies ist vorteilhaft, weil aufgrund der unterschiedliche langen Liegezeit der digital-bedruckten Rolle von 1 Tag bis mehrere Monate der Abklatsch (Set off) oder Migration unterschiedlich groß sein kann. Durch die Coronavorbehandlung wird dann trotz gegebenenfalls großen Setoffs eine gute Haftung des Schutzlacks erzielt.This is advantageous because, due to the different long idle time of the digitally printed roll from 1 day to several months, the set-off or migration can be of different sizes. Due to the corona pretreatment a good adhesion of the protective lacquer is achieved despite possibly large setoff.

Gemäß einem Ausführungsbeispiel wird ein auf einem organischen Lösemittel basierender Schutzlack verwendet.In one embodiment, an organic solvent-based resist is used.

Der Auftrag des lösemittelhaltigen Schutzlacks (009) kann auf einer separaten Anlage oder inline auf der Digitaldruckanlage erfolgen.The order of the solvent-based protective coating (009) can be made on a separate system or inline on the digital printing system.

Gemäß einem Ausführungsbeispiel kann ein strahlenhärtender Schutzlack verwendet werden. Dieser kann gemäß einem Ausführungsbeispiel mittels eines Elektrobeamers ausgehärtet werden. Gemäß eines weiteren Ausführungsbeispiels mittels UV-Härtung.According to one embodiment, a radiation-curing protective lacquer may be used. This can according to one embodiment by means of a Elektrobeamers be cured. According to another embodiment by means of UV curing.

Für das digitale Bedrucken wird gemäß einem Ausführungsbeispiel eine Druckmaschine vom Typ HP Indigo verwendet. Da diese nicht explosionsgeschützt und somit nicht für eine Verwendung eines auf einem organischen Lösemittel basierenden Primer geeignet ist, erfolgt das Primern vorzugsweise auf einer separaten Anlage.For digital printing, according to one embodiment, an HP Indigo type printing machine is used. Since this is not explosion-proof and thus not suitable for use of a primer based on an organic solvent, priming is preferably carried out on a separate unit.

Gemäß einem Ausführungsbeispiel erfolgt das Bedrucken eines Folienverbunds im Aussendruck mit Digitaldruck, so dass die weiteren Arbeitsschritte wie etwa Kaschieren entfallen, die beim Innendruck nötig sind.According to one embodiment, the printing of a film composite in the external printing is done with digital printing, so that the further steps such as laminating omitted, which are necessary for internal pressure.

Gemäß einem ersten Ausführungsbeispiel wird vorzugsweise ein auf einem organischen Lösemittel basierter Primer verwendet, der die Stabilität des Drucks verbessert.According to a first embodiment, it is preferable to use an organic solvent-based primer which improves the stability of the pressure.

Daneben wird gemäß eines Ausführungsbeispiels sowohl vor dem Primern wie auch vor dem Drucken und vor dem Auftragen des Schutzlacks eine Coronavorbehandlung durchgeführt. Dadurch wird ein besonders stabiles Druckbild erzielt, das auch die hohen mechanischen, thermischen und chemischen Stabilitätserfordernisse von zu versiegelnden Folien erfüllt.In addition, according to one embodiment, a corona pre-treatment is carried out both before the priming and before the printing and before the application of the protective lacquer. As a result, a particularly stable printed image is achieved, which also meets the high mechanical, thermal and chemical stability requirements of films to be sealed.

Eine derartige Coronavorbehandlung durchzuführen ist insbesondere vor den Schritten des Druckens und des Auftragens von Schutzlack nicht naheliegend, denn der Fachmann würde vermuten, dass die Coronavorbehandlung wegen ihrer Aggressivität negative Auswirkungen auf die Primerschicht hat und daher die Stabilität des Druckbildes negativ beeinträchtigt.Performing such a corona pretreatment is not obvious, especially before the steps of printing and applying protective varnish, because the person skilled in the art would suspect that the corona pretreatment has negative effects on the primer layer because of its aggressiveness and therefore adversely affects the stability of the printed image.

Die Erfinder der vorliegenden Erfindung haben jedoch erkannt, dass dies nicht der Fall ist, und dass insbesondere eine Coronavorbehandlung der geprimerten Schicht vordem B e d r u c k e n mit Digitaldruck, vorzugsweise auch noch eine Coronavorbehandlung der digital bedruckten Oberfläche vor dem Auftragen von Schutzlack, die Stabilität des Druckbildes erhöht und insbesondere eine ausreichende mechanische, thermische und chemische Stabilität für siegelfähige Folien erreicht wird. Besonders vorteilhaft ist es daher, wenn sowohl vor dem Primern wie auch vor dem Digitaldruck und auch vor dem Auftragen von Schutzlack eine Coronavorbeihandlung erfolgt.However, the inventors of the present invention have recognized that this is not the case and that in particular a corona pretreatment of the primed layer prior to printing with digital printing, preferably also a corona pretreatment of the digitally printed surface prior to the application of resist, increases the stability of the print image and in particular one sufficient mechanical, thermal and chemical stability is achieved for sealable films. It is therefore particularly advantageous if a corona pretreatment takes place both before the priming and before the digital printing and also before the application of protective lacquer.

Besonders vorteilhaft ist es ferner, wenn der Primer ein auf einem organischen Lösemittel basierender Primer, vorzugsweise ein Zwei-Komponenten-Primer ist.It is furthermore particularly advantageous if the primer is an organic solvent-based primer, preferably a two-component primer.

Gemäß einem Ausführungsbeispiel erfolgt ferner das Drucken mit einer Maschine des Typs HP Indigo.In one embodiment, printing is also done with an HP Indigo type machine.

Figur 1 illustriert schematisch den Verfahrensgang gemäß einem bevorzugten Ausführungsbeispiel. FIG. 1 schematically illustrates the process according to a preferred embodiment.

Der Mehrschichtverbund (001) weist eine Druckseite (003) und eine Siegelseite (002) auf.The multi-layer composite (001) has a pressure side (003) and a sealing side (002).

Auf der Druckseite erfolgt zunächst eine Coronavorbehandlung (004), dann das Auftragen des Primers (005). Darauf erfolgt eine weitere Coronavorbehandlung (006), dann der Digitaldruck (007). Nach einer erneuten Coronavorbehandlung (008) wird der Schutzlack aufgetragen (009).On the print side, first a corona pretreatment (004), then the application of the primer (005). This is followed by another corona pretreatment (006), then digital printing (007). After another corona pretreatment (008) the protective lacquer is applied (009).

Mit einem derartigen Druckverfahren lässt sich ein bedruckter Verbund herstellen, der die besonderen chemischen, thermischen und mechanischen Stabilitätserfordernisse für siegelfähige Verbunde erfüllt.Such a printing process can be used to produce a printed composite which meets the particular chemical, thermal and mechanical stability requirements for sealable composites.

Gemäß einem Ausführungsbeispiel umfasst die Erfindung einen durch ein erfindungsgemäßes Verfahren hergestellte Folie bzw. einen Folienverbund, der vor der Primerung, vor der digitalen Bedruckung und vor dem Auftragen des Schutzlacks coronavorbehandelt wurde.According to one embodiment, the invention comprises a film produced by a process according to the invention or a film composite which has been corona-treated prior to the priming, before the digital printing and before the application of the protective lacquer.

Dem Fachmann ist klar, dass die Merkmale der vorstehend beschriebenen Ausführungsbeispiele auch beliebig miteinander kombiniert werden können, solche Kombinationen sind durch die vorliegende Offenbarung mit umfasst.It will be understood by those skilled in the art that the features of the embodiments described above may be combined as desired, such combinations being encompassed by the present disclosure.
