Abstract

The invention relates to a printed thermoformable laminate comprised of at least two plastic films. The printing is placed between plastic films inside the laminate in order to increase protection against forgery. Preferred laminates have the following structure: film A / print / laminating agent /
film C; film A / print / laminating agent / film B / laminating agent / film C, and; film A / print / laminating agent / film B / laminating agent / print / film C.

Description

Printed thermoformabMe laminate with increased security against forgery The invention relates to a printed thermoformable laminate made of at least two plastics material films.
Thermoformable plastics material laminates may be printed for customer information before or after forming. The printing of the laminates before the thermoforming into containers or beakers takes place prirriarily on the container wall with current printirig methods. If the plastics material laminate is printed before the thermoforming the printing may detach to a greater or lesser extent from the laminate surface during forming or during the logistics because of the reduced adhesion of the printing dyes to the background, as a function of the degree of forming.

In the two cases of conventional printing, the print is located on the outside of the laminate surface formirig the packaging and is therefore easily accessible for forgeries, in that the print can be removed from the packaging and can easily be replaced by printing on new information.

When using pre-printed laminates, there is also the possibility that these may be produced by forgers, as plastics material films and laminates made of plastics materials are available to an almost unlimited extent commercially.

The invention is based on the object of providing a thermoformable laminate of the type mentioned at the outset with a printing such that, in comparison to the printed thermoformable laminates according to the prior art, a substantially higher degree of security against forgery is produced.

The fact that the printing is arranged between adjacent plastics material films to increase the security against forgery leads to the achievement of the object according to the invention.

The followirig structures are preferred for the laminates according to the invention:

film A/ print / laminating means / film C
film A/ print i laminating means / film B/ laminating means / film C
film A/ print / laminating means / film B/ laminating rrieans / print / film C.
The films A, B and C; are thermoformable plastics material films based on chlorinated hydrocarboris, such as polyvinyl chloride and polyvinylidene chloride, chlorofluorocarbons, for example ACLARO, polyolefins, polyethyleneterephthalates, polyacrylonitriles, for example BAREX , cycloolefin copolymers, cycloolefiri polymers, polysulphones or biologically degradable plastics materials, or combinations of these plastics materials in the laminate.
PVDC may be a film or a coating.

The total thickness of the laminates is 150 to 500 pm and also 90 to 150 pm in PVC/PE laminates.

The lamination takes place with laminatirig adhesives based on water, with solvent-based or solvent-free laminating adhesives and/or by extrusion lamination as monoextrusion or coextrusion. In the case of COC or COP laminates with PE
or PP, a lacquer lamination or else the production of a partial laminate by coextrusion is recommended.

The interlaminar bond of the individual layers should be at least 2 N/15 mm.

When using dyed films for the printing, the colour of the printed image may be changed by a corresponding choice of colour. For example, blue printing of a film which is dyed yellow leads to a printed image which appears green. The security against forgery of printed laminates cari be further iricreased with colour combinations of this type.
The preferred film combinations for the laminates according to the invention are compiled in Table 1. The abbreviations of the plastics materials on which the films are based mean~
