Definitions
- the invention relates to a method for producing a film material which is provided with a hologram embossing, and to such a film material.
- holograms or holographic structures are applied to the packaging material, in particular embossed therein, in order to make the packaging material and the product packaged with it distinguishable from other products.
- a holographic embossing process is known from DE 37 44 650 A1, in which a substrate is provided with a lacquer layer, the material is then metallized, and finally a hologram is embossed through the metallization. Varnishes with special properties are required for such a process. Lacquers which cure under UV light are known for this purpose, the lacquers not being fully cured at the time of embossing, so that the embossed structure can be applied. Finally, the material is usually coated with a protective varnish and then it can be cut into narrow rolls. Alternatively, it is known to carry out the metallization after the point in time at which the partially hardened lacquer is embossed.
- the protective lacquer applied as the top layer is required to protect the fine embossed structures and to produce the required abrasion resistance and lubricity of the material.
- a disadvantage of the known holographic embossing processes is that they always require an additional, separate work step during the manufacturing process. In particular, the embossing process must be carried out before the protective lacquer is applied. The problem that arises here is that it is uneconomical to produce small lot sizes with changing embossing motifs, since the metallization and top coating only work for large lot sizes, i.e. H. large roles, economically.
- Packaging material according to DE 299 00 043 Ul and DE 299 04 872 Ul also has a plastic layer as the outer layer, which leads to the problems mentioned in terms of economy.
- the invention is based on the object of providing an economically improved process for producing a film material provided with a hologram, and an economically producible film material.
- the film material is optionally first metallized.
- the method according to the invention is fundamentally suitable both for metal foils, for example aluminum foils, and metal-paper composites, in particular aluminum-paper composites, but also for paper, which accordingly has to be metallized in a first process step.
- d. H. is to be provided with a thin metal layer.
- a lubricant is then applied as part of the method according to the invention.
- the metallized or metal layer is embossed.
- the step usually required according to the prior art to apply a suitable lacquer in which the embossed structures are formed is eliminated. Rather, it will be described in detail.
- embossing made directly on the metal layer.
- the lubricant ensures that the required structures without the risk of the metal peeling off can be trained.
- the embossing is carried out directly on the finished film material, since the embossing is not carried out on a lacquer which is subsequently to be hardened, nor is a top coat or protective lacquer applied subsequently required. It has been found in tests that the embossed surface can form the uppermost layer of the film material produced according to the invention, with the exception of the lubricant layer which is present at least in residues even after embossing.
- Lubricants which can be used in connection with the present invention preferably belong to the following chemical classes: paraffins, polyethylene waxes, polypropylene waxes modified with maleic anhydride, ester and acid waxes, amide waxes, polytetrafluoroethylene waxes, polytetrafluoroethylene / polyethylene waxes, ethyl vinyl acetate Copolymer waxes, natural waxes, fatty alcohols, fatty acids, metal soaps, fatty acid esters, solid acid amides, siloxanes and sulfated oils. According to the invention, they can be used as a single compound or in mixtures which are compatible with one another. Most lubricants are commercially available and can be used directly without further preparation.
- the lubricant is a paraffin, it is preferably selected from predominantly branched-chain liquid hydrocarbons or from predominantly straight-chain solid hydrocarbons.
- Polyethylene waxes as lubricants are advantageously selected from polyethylenes with an average molecular weight of 2,000 to 12,000 or from air-oxidized low molecular weight polyethylenes.
- a preferred natural wax is carnauba wax.
- Stearic acid, 12-hydroxystearic acid and montanic acids mixture of long-chain carboxylic acids with 26 to 33 carbon atoms.
- Metal soaps are also suitable as lubricants. Calcium stearate, magnesium stearate and zinc stearate are preferably used.
- Fatty acid esters as lubricants are preferably selected from fatty acid esters of short-chain monohydric alcohols, fatty acid esters of long-chain monohydric alcohols, glycol
- Fatty acid esters Fatty acid esters, glycerol fatty acid esters, montanic acid ester waxes, solid or liquid high molecular weight mixed esters or from esters of polybasic carboxylic acids.
- Typical representatives of this class of compounds are n-butyl stearate, stearyl stearate, propylene glycol onooleate, glycerol monooleate, glycerol monostearate, distearyl adipate, distearyl phthalate and polycondensates
- Fatty acid amide selected from oleic acid amide, erucic acid amide or stearic acid amide, or N, N '-bis-stearoyl-ethylenediamine.
- the lubricant is usually applied by applying it as a dispersion and then drying it.
- the solvent used evaporates, leaving a comparatively firm application of lubricant.
- a film material with a hologram embossing can also be produced, which consists of a metal-paper composite, in particular an aluminum-paper composite.
- a composite material is to be coated with lubricant on the foil side, that is to say the metal side, within the scope of the method according to the invention and can also be processed according to the invention without the need for a coating application and processed into a foil material with hologram embossing.
- the lubricant For the application of the lubricant, it has proven to be advantageous to apply the lubricant in an amount of the order of 0.02 g / m 2 . This enables the required machinability, in particular the possibility of embossing, to be ensured in an economically advantageous manner.
- the method according to the invention since the method according to the invention does not require a final application of protective lacquer, which may require hardening, the method according to the invention prefers a cutting process with embossing in one operation with further economic advantages.
- the material according to the invention can be used on a combined embossing and cutting machine, in particular a roll cutting machine, getting produced. The material can then be wound up into at least one roll with little effort.
- the film material described in claim 5 has a metal layer provided with a hologram embossing and a lubricant layer which is at least partially formed on the finished film material on the metal layer.
- the method according to the invention is reflected in the associated film material in that only the
- Metal layer and / or the lubricant layer form the top layer of the material.
- no protective lacquer is required on the film material.
- Inner film of cigarette packaging can be used.
- the film material according to the invention can be found in further claims.
- it is preferred for the film material that it is a metallized paper, a metal, in particular an aluminum foil or a metal-paper composite, in particular an aluminum-paper composite.
- the required machinability for producing the film material according to the invention can be ensured in that the finished material has a lubricant order in the order of 0.02 g / m 2 .
- the film material according to the invention is present as a roll material.

Description
Verfahren zur Herstellung eines mit einer Hologrammpragung versehenen Folienmaterials sowie Folienmaterial Process for producing a film material provided with a hologram embossing and film material
Technisches GebietTechnical field
Die Erfindung betrifft ein Verfahren zur Herstellung eines Folienmaterials , das mit einer Hologrammprägung versehen ist , sowie ein derartiges Folienmaterial .The invention relates to a method for producing a film material which is provided with a hologram embossing, and to such a film material.
Insbesondere auf dem Gebiet der Verpackungstechnologie setzt es sich immer mehr durch, die Verpackungen durch besondere Ausstattungsmerkmale von Wettbewerbsprodukten zu differenzieren und insbesondere die Fälschung von Markenprodukten leichter erkennbar zu machen . Hierbei werden beispielsweise Hologramme oder holographische Strukturen auf das Verpackungsmaterial aufgebracht , insbesondere in dieses geprägt, um das Verpackungsmaterial sowie das damit verpackte Produkt von anderen Produkten unterscheidbar zu machen .
Stand der TechnikIn the field of packaging technology in particular, it is becoming increasingly popular to differentiate packaging from special products with special features and, in particular, to make counterfeiting of branded products easier to identify. Here, for example, holograms or holographic structures are applied to the packaging material, in particular embossed therein, in order to make the packaging material and the product packaged with it distinguishable from other products. State of the art
Aus der DE 37 44 650 AI ist ein holographisches Prägeverfahren bekannt, bei dem ein Substrat mit einer Lackschicht versehen wird, anschließend eine Metallisierung des Materials vorgenommen wird, und schließlich ein Hologramm durch die Metallisierung hindurch eingeprägt wird. Zu einem derartigen Verfahren sind Lacke mit besonderen Eigenschaften erforderlich. Bekannt sind hierfür Lacke, die unter UV-Licht aushärten, wobei die Lacke zum Zeitpunkt der Prägung noch nicht vollständig ausgehärtet sind, so dass die Prägestruktur aufgebracht werden kann. Abschließend wird das Material üblicherweise mit einem Schutzlack versehen, und nachfolgend kann es zu schmalen Rollen geschnitten werden. Alternativ ist es bekannt, die Metallisierung nach dem Zeitpunkt, zu dem die Prägung des teilweise ausgehärteten Lackes erfolgt, vorzunehmen. Der als oberste Schicht aufgebrachte Schutzlack ist erforderlich, um die feinen Prägestrukturen zu schützen, und die erforderliche Abriebfestigkeit und Gleitfähigkeit des Materials zu erzeugen. An den bekannten holographischen Prageverfahren ist nachteilig, dass sie stets während des Herstellungsprozesses einen zusätzlichen, separaten Arbeitsgang erfordern. Insbesondere uss der Prägevorgang vor dem Aufbringen des abdeckenden Schutzlackes erfolgen. Hierbei tritt das Problem auf, dass es unwirtschaftlich ist, kleine Losgrößen mit wechselnden Prägemotiven herzustellen, da die Metallisierung und Decklackierung nur bei großen Losgrößen, d. h. großen Rollen, wirtschaftlich durchzuführen ist.A holographic embossing process is known from DE 37 44 650 A1, in which a substrate is provided with a lacquer layer, the material is then metallized, and finally a hologram is embossed through the metallization. Varnishes with special properties are required for such a process. Lacquers which cure under UV light are known for this purpose, the lacquers not being fully cured at the time of embossing, so that the embossed structure can be applied. Finally, the material is usually coated with a protective varnish and then it can be cut into narrow rolls. Alternatively, it is known to carry out the metallization after the point in time at which the partially hardened lacquer is embossed. The protective lacquer applied as the top layer is required to protect the fine embossed structures and to produce the required abrasion resistance and lubricity of the material. A disadvantage of the known holographic embossing processes is that they always require an additional, separate work step during the manufacturing process. In particular, the embossing process must be carried out before the protective lacquer is applied. The problem that arises here is that it is uneconomical to produce small lot sizes with changing embossing motifs, since the metallization and top coating only work for large lot sizes, i.e. H. large roles, economically.

Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zu Grunde, ein wirtschaftlich verbessertes Verfahren zur Herstellung eines mit einer Hologrammpr gung versehenen Folienmaterials, sowie ein wirtschaftlicher herstellbares Folienmaterial zu schaffen.The invention is based on the object of providing an economically improved process for producing a film material provided with a hologram, and an economically producible film material.
Die Lösung dieser Aufgabe erfolgt durch das Verfahren nach dem Patentanspruch 1 sowie das Folienmaterial nach dem Patentanspruch 5.This object is achieved by the method according to claim 1 and the film material according to claim 5.
Im Rahmen des erfindungsgemäßen Verfahrens ist vorgesehen, dass das Folienmaterial gegebenenfalls zunächst metallisiert wird. Es sei an dieser Stelle erwähnt, dass sich das erfindungsgemäße Verfahren grundsätzlich sowohl für Metallfolien, beispielsweise Aluminiumfolien, sowie Metall-Papier-Verbunde, insbesondere Aluminium-Papier-Verbunde, aber auch für Papier eignet, das dementsprechend in einem ersten Verfahrensschritt zunächst zu metallisieren, d. h. mit einer dünnen Metallschicht zu versehen ist. Im Rahmen des erfindungsgemäßen Verfahrens wird anschließend ein Gleitmittel aufgetragen.Within the scope of the method according to the invention, it is provided that the film material is optionally first metallized. It should be mentioned at this point that the method according to the invention is fundamentally suitable both for metal foils, for example aluminum foils, and metal-paper composites, in particular aluminum-paper composites, but also for paper, which accordingly has to be metallized in a first process step. d. H. is to be provided with a thin metal layer. A lubricant is then applied as part of the method according to the invention.
Unmittelbar daran anschließend erfolgt die Prägung der metallisierten bzw. der Metallschicht. Mit anderen Worten entfällt der üblicherweise gemäß dem Stand der Technik erforderliche Schritt, einen geeigneten Lack aufzubringen, in dem die Prägestrukturen ausgebildet werden. Vielmehr wird dasImmediately afterwards, the metallized or metal layer is embossed. In other words, the step usually required according to the prior art to apply a suitable lacquer in which the embossed structures are formed is eliminated. Rather, it will
Prägen unmittelbar an der Metallschicht vorgenommen. Das Gleitmittel stellt hierbei sicher, dass die erforderlichen Strukturen ohne die Gefahr eines Abblätterns des Metalls
ausgebildet werden können. Im wesentlichen erfolgt die Prägung unmittelbar auf dem fertigen Folienmaterial, indem die Prägung weder auf einem nachfolgend noch auszuhärtenden Lack erfolgt, noch ein abschließend aufgetragener Deck- oder Schutzlack • erforderlich ist. Es hat sich nämlich bei Versuchen herausgestellt, dass die geprägte Oberfläche mit Ausnahme der zumindest in Resten auch nach dem Prägen vorhandenen Gleitmittelschicht die oberste Schicht des erfindungsgemäß hergestellten Folienmaterials bilden kann.Embossing made directly on the metal layer. The lubricant ensures that the required structures without the risk of the metal peeling off can be trained. Essentially, the embossing is carried out directly on the finished film material, since the embossing is not carried out on a lacquer which is subsequently to be hardened, nor is a top coat or protective lacquer applied subsequently required. It has been found in tests that the embossed surface can form the uppermost layer of the film material produced according to the invention, with the exception of the lubricant layer which is present at least in residues even after embossing.
Ein Überziehen mit Schutzlack kann entfallen. Das erfindungsgemäße Verfahren schafft somit eine merkliche wirtschaftliche Verbesserung. Im Hinblick auf das erfindungsgemäß zu bearbeitende Folienmaterial sei erwähnt, dass es sich hierbei um Material gemäß der EP 0 676 503 AI handeln kann, deren Offenbarung hiermit hinsichtlich des erfindungsgemäß verwendeten Materials vollständig zum Gegenstand der vorliegenden Anmeldung gemacht wird. Nachdem das darin erwähnte Material bereits einen Gleitmittelauftrag aufweist, versteht es sich, dass ein zusätzlicher Auftrag eines Gleitmittels nicht unbedingt erforderlich, jedoch jederzeit möglich ist.Covering with protective lacquer can be omitted. The method according to the invention thus creates a noticeable economic improvement. With regard to the film material to be processed according to the invention, it should be mentioned that this can be material according to EP 0 676 503 A1, the disclosure of which is hereby fully made the subject of the present application with regard to the material used according to the invention. Since the material mentioned therein already has a lubricant application, it goes without saying that an additional application of a lubricant is not absolutely necessary, but is possible at any time.
Für das Gleitmittel wird bevorzugt ein Gleitmittel gewählt, das einen Erweichungspunkt aufweist, der oberhalb der beim Prägen auftretenden Temperatur liegt. Hierdurch kann in vorteilhafter Weise eine effiziente Herstellung sichergestellt werden. Im Zusammenhang mit der vorliegenden Erfindung verwendbare Gleitmittel gehören bevorzugt den folgenden chemischen Klassen an: Paraffine, Polyethylen-Wachse, mit Maleinsäureanhydrid modifizierte Polypropylen-Wachse, Ester- und Säurewachse, Amidwachse, Polytetrafluorethylen-Wachse, Polytetrafluorethylen/Polyethylen-Wachse, Ethyl-Vinylacetat-

Ist das Gleitmittel ein Paraffin, ist es bevorzugt ausgewählt aus vorwiegend verzweigtkettigen flüssigen Kohlenwasserstoffen oder aus vorwiegend geradkettigen festen Kohlenwasserstoffen.If the lubricant is a paraffin, it is preferably selected from predominantly branched-chain liquid hydrocarbons or from predominantly straight-chain solid hydrocarbons.
Polyethylen-Wachse als Gleitmittel werden vorteilhaft aus Polyethylenen mit einer mittleren Molmasse von 2000 bis 12000 oder aus luftoxidierten niedermolekularen Polyethylenen ausgewählt .Polyethylene waxes as lubricants are advantageously selected from polyethylenes with an average molecular weight of 2,000 to 12,000 or from air-oxidized low molecular weight polyethylenes.
Ein bevorzugtes Naturwachs ist Carnaubawachs .A preferred natural wax is carnauba wax.
Typische Vertreter von Fettsäuren als Gleitmittel sindTypical representatives of fatty acids as lubricants are
Stearinsäure, 12-Hydroxystearinsäure und Montansäuren (Gemisch langkettiger Carbonsäuren mit 26 bis 33 Kohlenstoffatomen) .Stearic acid, 12-hydroxystearic acid and montanic acids (mixture of long-chain carboxylic acids with 26 to 33 carbon atoms).
Auch Metallseifen sind als Gleitmittel geeignet. Bevorzugt werden Calciumstearat, Magnesiumstearat and Zinkstearat verwendet .Metal soaps are also suitable as lubricants. Calcium stearate, magnesium stearate and zinc stearate are preferably used.

Das Gleitmittel wird üblicherweise dadurch aufgetragen, dass es als Dispersion aufgebracht wird und nachfolgend trocknet. Das verwendete Lösungsmittel verdunstet hierbei, so dass ein vergleichsweise fester Gleitmittelauftrag verbleibt.The lubricant is usually applied by applying it as a dispersion and then drying it. The solvent used evaporates, leaving a comparatively firm application of lubricant.
Im Hinblick auf das Prägen eines Hologramms im Rahmen des erfindungsgemäßen Verfahrens sei erwähnt, dass hierbei imWith regard to the embossing of a hologram in the context of the method according to the invention, it should be mentioned that
Gegensatz zu einer sonstigen Prägung, bei welcher das Material gesamthaft verformt wird, lediglich eine Verformung der Oberfläche erfolgt. Mit anderen Worten bleibt bei einer Hologrammpr gung die nicht bearbeitete "Rückseite" weitgehend eben. Eine typische Materialdicke des hierbei verwendeten Folienmaterials beträgt etwa 50 μm. Typisch für das Prägen eines Hologramms ist ferner ein Abstand der Prägelinien, der sich im Bereich unterhalb eines Mikrometers, beispielsweise bei 0,5 μm, befindet. Schließlich wird im Rahmen der Erfindung bevorzugt, dass das Prägen in einem kontinuierlichen Verfahren, beispielsweise rotativ, d.h. durch sich drehende Walzen, erfolgt .
Bevorzugte Weiterbildungen des erfindungsgemäßen Verfahrens sind in den Ansprüchen 2 bis 4 beschrieben .In contrast to other embossing, in which the material is deformed as a whole, only the surface is deformed. In other words, in the case of a hologram embossing, the unprocessed “rear side” remains largely flat. A typical material thickness of the film material used here is approximately 50 μm. Also typical for embossing a hologram is a distance between the embossing lines, which is in the range below a micrometer, for example at 0.5 μm. Finally, it is preferred within the scope of the invention that the embossing takes place in a continuous process, for example by rotation, that is to say by rotating rollers. Preferred developments of the method according to the invention are described in claims 2 to 4.
Besonders gute Erfahrungen im Rahmen des erfindungsgemäßen Verfahrens wurden einerseits mit Papier gemacht , das zunächst metallisiert wird . Ferner ist das erfindungsgemäße Verfahren in vorteilhafter Weise auf Metall- insbesondere Aluminiumfolien oder -bänder anwendbar . Schließlich kann im Rahmen des Verfahrens auch ein Folienmaterial mit einer Hologrammprägung hergestellt werden, das aus einem Metall-Papier-Verbund, insbesondere einem Aluminium- Papier-Verbund besteht . Ein derartiges Verbundmaterial ist im Rahmen des erfindungsgemäßen Verfahrens auf der Folien- also der Metallseite mit Gleitmittel zu beschichten und kann ebenfalls ohne die Notwendigkeit eines Lackauftrages erfindungsgemäß bearbeitet und zu einem Folienmaterial mit Hologrammprägung verarbeitet werden .On the one hand, particularly good experiences in the context of the method according to the invention have been made with paper which is first metallized. Furthermore, the method according to the invention is advantageously applicable to metal, in particular aluminum foils or strips. Finally, within the scope of the method, a film material with a hologram embossing can also be produced, which consists of a metal-paper composite, in particular an aluminum-paper composite. Such a composite material is to be coated with lubricant on the foil side, that is to say the metal side, within the scope of the method according to the invention and can also be processed according to the invention without the need for a coating application and processed into a foil material with hologram embossing.
Für den Auftrag des Gleitmittels hat es sich als vorteilhaft herausgestellt , das Gleitmittel in einer Menge in der Größenordnung von 0 , 02 g/m2 aufzubringen . Hierdurch kann in wirtschaftlich günstiger Weise die erforderliche Bearbeitbarkeit , insbesondere die Möglichkeit der Prägung sichergestellt werden .For the application of the lubricant, it has proven to be advantageous to apply the lubricant in an amount of the order of 0.02 g / m 2 . This enables the required machinability, in particular the possibility of embossing, to be ensured in an economically advantageous manner.
Da nach dem erfindungsgemäßen Verfahren kein abschließender Schutzlackauftrag erforderlich ist , der unter Umständen ein Härten benötigt, wird im Rahmen des erfindungsgemäßen Verfahrens bevorzugt und mit weiteren wirtschaftlichen Vorteilen in einem Arbeitsgang mit dem Prägen ein Schneidvorgang durchgeführt . Insbesondere kann das erfindungsgemäße Material auf einer kombinierten Präge- und Schneidemaschine, insbesondere einer Rollenschneidemaschine ,
hergestellt werden. Anschließend kann das Material mit geringem Aufwand zu zumindest einer Rolle aufgewickelt werden.Since the method according to the invention does not require a final application of protective lacquer, which may require hardening, the method according to the invention prefers a cutting process with embossing in one operation with further economic advantages. In particular, the material according to the invention can be used on a combined embossing and cutting machine, in particular a roll cutting machine, getting produced. The material can then be wound up into at least one roll with little effort.
Die Lösung der obengenannten Aufgabe erfolgt ferner durch das im Anspruch 5 beschriebene Folienmaterial . Dieses weist eine mit einer Hologrammprägung versehene Metallschicht sowie eine Gleitmittelschicht auf, die an dem fertigen Folienmaterial zumindest teilweise auf der Metallschicht ausgebildet ist. Das erfindungsgemäß Verfahren spiegelt sich in dem zugehörigen Folienmaterial dadurch wider, dass ausschließlich dieThe above object is also achieved by the film material described in claim 5. This has a metal layer provided with a hologram embossing and a lubricant layer which is at least partially formed on the finished film material on the metal layer. The method according to the invention is reflected in the associated film material in that only the
Metallschicht und/oder die Gleitmittelschicht die oberste Schicht des Materials bilden. Mit anderen Worten ist erfindungsgemäß kein Schutzlack auf dem Folienmaterial erforderlich. Es wird somit ein äußerst wirtschaftlich herstellbares Material geschaffen, das beispielsweise alsMetal layer and / or the lubricant layer form the top layer of the material. In other words, according to the invention, no protective lacquer is required on the film material. An extremely economically producible material is thus created which, for example, as
Innenfolie von Zigarettenverpackungen verwendet werden kann.Inner film of cigarette packaging can be used.
Bevorzugte Ausführungsformen des erfindungsgemäßen Folienmaterials finden sich in weiteren Ansprüchen. Im wesentlichen in Übereinstimmung mit den Ausfuhrungsformen des erfindungsgemäßen Verfahrens wird für das Folienmaterial bevorzugt, dass es ein metallisiertes Papier, eine Metall-, insbesondere eine Alufolie oder ein Metall-Papier-Verbund, insbesondere ein Aluminium-Papier-Verbund ist.Preferred embodiments of the film material according to the invention can be found in further claims. Essentially in accordance with the embodiments of the method according to the invention, it is preferred for the film material that it is a metallized paper, a metal, in particular an aluminum foil or a metal-paper composite, in particular an aluminum-paper composite.
Die erforderliche Bearbeitbarkeit zur Herstellung des erfindungsgemäßen Folienmaterials kann dadurch gewährleistet werden, dass das fertige Material einen Gleitmittelauf rag in einer Größenordnung von 0 , 02 g/m2 aufweist .The required machinability for producing the film material according to the invention can be ensured in that the finished material has a lubricant order in the order of 0.02 g / m 2 .
Schließlich wird unter Wirtschaf tlichkeits- und Transportgesichtspunkten für das erfindungsgemäße Folienmaterial bevorzugt , dass es als Rollenmaterial vorliegt .
Finally, from the point of view of economy and transport, it is preferred for the film material according to the invention that it is present as a roll material.
