Abstract
The present disclosure provides a multilayer cold-formable film carrying an image which comprises a first layer and a base layer laminated to the first layer and its preparation. The first layer comprises a peelable carrier, a coat of an ester acrylic based primer, a metallized layer, an adhesive coat embossed with an image of a pre-determined pattern. The present disclosure also provides a multi-layer cold-formed anti-counterfeit package.
Claims20
A multilayer cold-formable film carrying an image and having a thickness in the range of 100 to 300 micron;
- said film comprises;
- a) a first layer comprising:
- i. a peelable carrier having a thickness ranging from 10 to 20 micron;
- ii. a coat of an ester acrylic based primer having a thickness ranging from 0.1 to 10 micron on said carrier;
- iii. a metallized layer having a thickness ranging from 0.001 to 0.3 micron deposited on said coat;
- iv. an adhesive coat provided on said metalized layer;
- and
- v. an image of a pre-determined pattern embossed on said coat forming an embossed surface, and
- b) a base layer having a thickness ranging from 100 to 250 micron laminated to said embossed surface of the first layer.
A process for the preparation of a multilayer cold-formable film carrying an image and having a thickness in the range of 100 to 300 micron;
- said process comprises the following steps:
- selecting a peelable carrier having a thickness ranging from 10 to 20 micron, said carrier comprises at least one polyester film, preferably, polyethylene terephthalate (PET);
- applying a coat of an ester acrylic based adhesive having a thickness ranging from 0.1 to 10 micron on the carrier;
- partially drying the coat;
- depositing a metallized layer having a thickness ranging from 0.001 to 0.3 micron on the partially dried coat to obtain a metallized carrier, said metallized layer comprises at least one 99% pure metal selected from the group consisting of aluminum, platinum, gold, silver and copper or at least one 99% pure metal compound selected from the group consisting of Zinc oxide, zinc sulfide and silicon oxide;
- coating at least one layer of an adhesive coat on the metallized carrier, said adhesive is selected from the group consisting of polyurethane, acrylic polymer, isocyanides and combinations thereof;
- embossing an image of a pre-determined pattern on said coat with a shim to form a first layer with an embossed surface;
- providing a base layer having a thickness ranging from 100 to 250 micron, said base layer is selected from a group consisting of a transparent base, a translucent base and an opaque base, said base layer comprises at least one polymeric film selected from the group consisting of nylon, nylon 66, polyvinyl chloride (PVC), high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP), amorphous polyethylene terephthalate (APET), co-polymer of PET with glycol (PETg), Polyethylene (PE), polyester, polyamide, polystyrene, copolymers of polystyrene, ethylene vinyl alcohol (EVOH) and combinations thereof;
- applying an adhesive layer having a thickness ranging from 1 to 10 micron to the base layer;
- laminating the base layer to the embossed surface of the first layer;
- and
- peeling the carrier to obtain a multilayer formable film carrying the image.
