Description

Fälschungssichere Verpackungsfolie für feste, flüssige oder gasförmige Güter Counterfeit-proof packaging film for solid, liquid or gaseous goods
Die Erfindung betrifft eine Verpackungsfolie für feste, flüssige oder gasförmige Güter, insbesondere für Streifen- oder Sachetpackungen.The invention relates to a packaging film for solid, liquid or gaseous goods, in particular for strip or Sachetpackungen.
Bei Verpackungen von festen, flüssigen oder gasförmigen Gütern ist es aus Qualitätsanforderungs-, Convenience-, Marketing- oder Informationsgründen erwünscht, dass für Anwender, Verbraucher, Großhändler oder Verkäufer der Inhalt einer Verpackung ohne Öffnen der Verpackung mit freiem Auge sichtbar ist.For packaging of solid, liquid or gaseous goods, it is desirable for quality, convenience, marketing or information purposes that the contents of a package be visible to users, consumers, wholesalers or sellers without opening the package.
Die Problematik von Produktfälschungen, unerlaubten Fertigungen oder anderen Fälschungen, Verfälschungen oder unerlaubten Importen, Re-importen und dergleichen erfordern aber auch, die Verpackungen mit eindeutig erkennbaren, fälschungssicheren Merkmalen zu versehen, die die Originalität und den Ursprung des verpackten Produkts belegen können und nachweisbar machen.However, the problem of counterfeiting, unauthorized manufacturing or other counterfeiting, adulteration or illicit imports, re-imports and the like also require the packaging to be provided with clearly identifiable, counterfeit-proof features which can prove and demonstrate the originality and origin of the packaged product ,
Dazu werden im Wesentlichen Etiketten verwendet, die auf die Verpackung aufgebracht werden. Diese Etiketten müssen jedoch in getrennten Arbeitsschritten auf der Verpackung platziert werden und verursachen somit zusätzliche Kosten bei der Herstellung.For this purpose, labels are mainly used, which are applied to the packaging. However, these labels need to be placed in separate steps on the packaging, thus causing additional manufacturing costs.
Ebenso sind manche Verpackungsformen nur schlecht oder gar nicht zur Aufnahme von Etiketten geeignet, insbesondere auf kleine Verpackungsformen können Etiketten, die alle nötigen Informationen aufweisen, aufgrund der notwendige Größe nur schwer aufgebracht werden.Likewise, some forms of packaging are poorly or not at all suitable for receiving labels, especially on small packaging forms labels that have all the necessary information, are difficult to apply due to the size required.
Außerdem können Etiketten durch geeignete Maßnahmen, wie Ablösen nach Einfrieren oder geeignete mechanische oder chemische Lösemittel, entfernt und auf andere Verpackungen oder Substrate wieder aufgebracht werden.In addition, labels may be removed by suitable means, such as peeling after freezing or suitable mechanical or chemical solvents, and reapplied to other packages or substrates.
Aufgabe der Erfindung war es daher, eine Verpackungsfolie bzw. eine Verpackung bereitzustellen, die zumindest teilweise transparent und fälschungssicher ist und gleichzeitig keine Einschränkungen bei der Gestaltung der Verpackung aufweist.The object of the invention was therefore to provide a packaging film or a packaging which is at least partially transparent and is forgery-proof and at the same time has no restrictions on the design of the packaging.
Gegenstand der Erfindung ist daher eine Sicherheitsverpackungsfolie, aufweisend ein Trägersubstrat, das zumindest ein Sicherheitsmerkmal aufweist, dadurch gekennzeichnet, dass das Trägersubstrat ein optisch aktives Element, wie ein Hologramm, ein Oberflächenrelief, ein Beugungsgitter oder ein Kinegramm aufweist, das einen zumindest teilweise transparenten Reflektor aufweist.The invention therefore relates to a security packaging film comprising a carrier substrate which has at least one security feature, characterized in that the carrier substrate has an optically active element, such as a hologram, a surface relief, a diffraction grating or a kinegram having an at least partially transparent reflector ,
Als Trägersubstrat kommen beispielsweise flexible, halbstarre oder starre Kunststofffolien, beispielsweise aus PI, PP, OPP, PE, PPS, PEEK, PEK, PEI, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC, PTFE, Fluorpolymere wie Teflon, PVB etc. in Frage.Examples of suitable carrier substrates are flexible, semi-rigid or rigid plastic films, for example PI, PP, OPP, PE, PPS, PEEK, PEK, PEI, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , PTFE, fluoropolymers such as Teflon, PVB, etc. in question.
Die Trägerfolien weisen vorzugsweise eine Dicke von 5 - 700 μm, bevorzugt 5 - 200 μm, besonders bevorzugt 5 - 50 μm auf.The carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
Zur Herstellung des Sicherheitsmerkmals wird vorerst UV-härtbarer eventuell mit geeigneten Pigmenten (beispielsweise) gelb eingefärbter Lack aufgebracht. Anschließend kann beispielsweise eine Oberflächenstruktur durch Abformen einer Matrize in diesen Lack, der zum Zeitpunkt der Abformung bis zum Gelpunkt vorgehärtet ist, hergestellt werden, worauf anschließend der strahlungshärtbare Lack nach Aufbringung der Oberflächenstruktur vollständig ausgehärtet wird.For the production of the security feature, UV-curable lacquer, which may have been colored yellow with suitable pigments (for example), is initially applied. Subsequently, for example, a surface structure can be produced by molding a matrix into this lacquer, which is pre-cured to the gel point at the time of the impression, whereupon the radiation-curable lacquer is then completely cured after application of the surface structure.
Durch die Verwendung des UV-härtbaren Lacks sind nach der Aushärtung darauf aufgebrachte Schichten, auch eine gegebenenfalls eingebrachte Oberflächenstruktur, auch unter Temperaturbelastung stabil.Due to the use of the UV-curable lacquer, layers which have been applied thereto after curing, and also an optionally introduced surface structure, are stable even under temperature load.
Der strahlungshärtbare Lack kann beispielsweise ein strahlungshärtbares Lacksystem auf Basis eines Polyester-, eines Epoxy oder Polyurethansystems das 2 oder mehr verschiedene, dem Fachmann geläufige Photoinitiatoren enthält, die bei unterschiedlichen Wellenlängen eine Härtung des Lacksystems in unterschiedlichem Ausmaß initiieren können. So kann beispielsweise ein Photoinitiator bei einer Wellenlänge von 200 bis 400 nm aktivierbar sein, der zweite Photoinitiator dann bei einer Wellenlänge von 370 bis 600 nm. Zwischen den Aktivierungswellenlängen der beiden Photoinitiatoren sollte genügend Differenz eingehalten werden, damit nicht eine zu starke Anregung des zweiten Photoinitiators erfolgt, während der erste aktiviert wird. Der Bereich, in dem der zweite Photoinitiator angeregt wird, sollte im Transmissionswellenlängenbereich des verwendeten Trägersubstrats liegen. Für die Haupthärtung (Aktivierung des zweiten Photoinitiators) kann auch Elektronenstrahlung verwendet werden.The radiation-curable lacquer may, for example, a radiation-curable lacquer system based on a polyester, an epoxy or polyurethane system, the 2 or more different, known in the art photoinitiators contains, which can initiate a hardening of the paint system to varying degrees at different wavelengths. Thus, for example, a photoinitiator can be activated at a wavelength of 200 to 400 nm, the second photoinitiator then at a wavelength of 370 to 600 nm. Between the activation wavelengths of the two photoinitiators sufficient difference should be maintained, so that not too strong excitation of the second photoinitiator takes place while the first is activated. The region in which the second photoinitiator is excited should be in the transmission wavelength range of the carrier substrate used. For the main curing (activation of the second photoinitiator) also electron radiation can be used.
Als strahlungshärtbarer Lack kann auch ein wasserverdünnbarer Lack verwendet werden. Bevorzugt werden Lacksysteme auf Polyesterbasis.As a radiation-curable varnish, a water-thinnable varnish can also be used. Preference is given to polyester-based paint systems.
Die Oberflächenstruktur wird anschließend mit einer metallischen Schicht oder einer metallisch erscheinenden Schicht versehen, die anschließend Feinst- demetallisiert wird.The surface structure is subsequently provided with a metallic layer or a metallic appearing layer, which is subsequently ultrafiltered.
Dazu wird partiell eine Farbschicht in Form von Linien Guillochen, Rastern, Rasterwinkelmodulationen oder Moireeffekten oder Codes oder ähnlichen Sicherheitsdruckelementen aufgebracht.For this purpose, a color layer in the form of lines guilloches, grids, screen angle modulations or Moireeffekten or codes or similar security printing elements is partially applied.
Die Aufbringung des Farbauftrags kann durch ein beliebiges Verfahren, beispielsweise durch Tiefdruck, Flexodruck, Siebdruck, Digitaldruck und dergleichen erfolgen.The application of the paint can be done by any method, for example by gravure printing, flexographic printing, screen printing, digital printing and the like.
Die verwendete Farbe bzw. der verwendete Farblack ist in einem Lösungsmittel, vorzugsweise in Wasser löslich, es kann jedoch auch eine in jedem beliebigen Lösungsmittel, beispielsweise in Alkohol, Estern und dergleichen lösliche Farbe verwendet werden. Die Farbe bzw. der Farblack können übliche Zusammensetzungen auf Basis von natürlichen oder künstlichen Makromolekülen sein. Die lösliche Farbe kann pigmentiert oder nicht pigmentiert sein. Als Pigmente können alle bekannten Pigmente verwendet werden. Besonders geeignet sind TiO2, ZnS, Kaolin und dergleichen.The color or lacquer used is soluble in a solvent, preferably water, but it is also possible to use a dye which is soluble in any solvent, for example in alcohol, esters and the like. The color or the colored lacquer can be customary compositions based on natural or artificial macromolecules. The soluble color can be pigmented or not be pigmented. As pigments, all known pigments can be used. Particularly suitable are TiO 2 , ZnS, kaolin and the like.
Anschließend wird das bedruckte Trägersubstrat mittels eines Inline-Plasma- (Niederdruck- oder Atmosphärenplasma-), Corona- oder Flammprozesses behandelt. Durch energiereiches Plasma, beispielsweise Ar- oder ArΛ-VPlasma wird die Oberfläche von Tonungsresten der Druckfarben gereinigt. Dabei wird die notwendige scharfe Abgrenzung der Konturen der Aussparungen, die für die notwenige Präzision der Codierung notwendig ist, erreicht. Gleichzeitig wird die Oberfläche aktiviert. Dabei werden endständige polare Gruppen an der Oberfläche erzeugt. Dadurch wird die Haftung von Metallen und dergleichen an der Oberfläche verbessert.Subsequently, the printed carrier substrate is treated by means of an in-line plasma (low pressure or atmospheric plasma), corona or flame process. By energetic plasma, for example Ar or ArΛ VPlasma the surface of Tonungsresten of the printing inks is cleaned. The necessary sharp delimitation of the contours of the recesses, which is necessary for the necessary precision of the coding is achieved. At the same time, the surface is activated. In this case, terminal polar groups are generated on the surface. This improves the adhesion of metals and the like to the surface.
Gegebenenfalls kann gleichzeitig mit der Anwendung der Plasma- bzw. Corona- oder Flammbehandlung eine dünne Metall- oder Metalloxidschicht als Haftvermittler, beispielsweise durch Sputtern oder Aufdampfen aufgebracht werden. Besonders geeignet sind dabei Cr, AI, Ag, Ti, Cu, TiO2, Si-Oxide oder Chromoxide. Diese Haftvermittlerschicht weist im allgemeinen eine Dicke von 0,1 nm - 5nm, vorzugsweise 0,2 nm - 2nm, besonders bevorzugt 0,2 bis 1 nm auf.Optionally, simultaneously with the application of the plasma or corona or flame treatment, a thin metal or metal oxide layer can be applied as adhesion promoter, for example by sputtering or vapor deposition. Particularly suitable are Cr, Al, Ag, Ti, Cu, TiO 2 , Si oxides or chromium oxides. This adhesion promoter layer generally has a thickness of 0.1 nm to 5 nm, preferably 0.2 nm to 2 nm, particularly preferably 0.2 to 1 nm.
Dadurch wird die Haftung der partiell oder vollflächig aufgebrachten strukturierten funktionellen Schicht weiter verbessert. Das ist Voraussetzung für die Erzeugung von funktionellen Schichten mit hoher Präzision und guter Haftung.As a result, the adhesion of the partially or completely applied structured functional layer is further improved. This is a prerequisite for the production of functional layers with high precision and good adhesion.
Diese Schicht besteht aus einem Metall, einer Metallverbindung, einer Legierung oder einem Isolator. Als Metallschicht sind Schichten aus AI, Cu, Fe, Ag, Au, Cr, Ni, Zn und dergleichen geeignet. Als Metallverbindungen sind beispielsweise Oxide oder Sulfide von Metallen, insbesondere TiO2, Cr-Oxide, ZnS, ITO, ATO, FTO, ZnO, AI2O3 oder Siliciumoxide geeignet. Geeignete Legierungen sind beispielsweise Cu-Al Legierungen, Cu-Zn Legierungen und dergleichen.This layer consists of a metal, a metal compound, an alloy or an insulator. As the metal layer, layers of Al, Cu, Fe, Ag, Au, Cr, Ni, Zn and the like are suitable. Examples of suitable metal compounds are oxides or sulfides of metals, in particular TiO 2 , Cr oxides, ZnS, ITO, ATO, FTO, ZnO, Al 2 O 3 or silicon oxides. suitable Alloys are, for example, Cu-Al alloys, Cu-Zn alloys and the like.
Diese funktionelle Schicht kann durch bekannte Verfahren, beispielsweise durch Bedampfen, Sputtem, Drucken (Tief-, Flexo-, Sieb-, Digitaldruck und dergleichen) , Sprühen, Galvanisieren und dergleichen aufgebracht werden. DieThis functional layer may be applied by known methods such as sputtering, sputtering, printing (gravure, flexo, screen, digital printing and the like), spraying, electroplating and the like. The
Dicke der funktionellen Schicht beträgt 0,001 bis 50 μm, vorzugsweise 0,1 bisThickness of the functional layer is 0.001 to 50 μm, preferably 0.1 to
20 μm.20 μm.
Anschließend wird die Farbschicht durch ein geeignetes Lösungsmittel, das auf die Zusammensetzung der Farbschicht abgestimmt ist, entfernt. Bevorzugt ist der Farbauftrag wasserlöslich. Gegebenenfalls kann die Ablösung durch mechanische Einwirkung unterstützt werden.Subsequently, the color layer is removed by a suitable solvent, which is adapted to the composition of the color layer. The application of paint is preferably water-soluble. Optionally, the separation can be supported by mechanical action.
Über die Gestaltung der Feinstdemetallisierung können auch stufenlose Übergänge zwischen vollflächigen opaken bis zu lichtdurchlässigen bis semitransparenten oder transparenten Bereichen gestaltet werden.Through the design of fine demetallization, stepless transitions between full-surface opaque to translucent to semitransparent or transparent regions can be designed.
Das Trägersubstrat kann anschließend mit einer Schutzbeschichtung oder einem Heißsiegellack versehen werden und anschließend konfektioniert werden.The carrier substrate can then be provided with a protective coating or a heat sealing lacquer and then assembled.
Die beschriebene Sicherheitsverpackungsfolie kann nun entweder als Oberoder Unterfolie einer transparenten Streifen- oder Sachetverpackung, Blisterverpackungen oder Sichtfensterverpackungen eingesetzt werden.The described security packaging film can now be used either as top or bottom film of a transparent strip or sachet packaging, blister packaging or window pane packaging.
Es wird somit eine fälschungssichere Verpackungsform bereitgestellt, bei welcher das Füllgut weiterhin durch die Feinstdemetallsierung sichtbar ist. There is thus provided a forgery-proof packaging form, in which the contents are still visible through the Feinstdemetallsierung.
