[Abstract] The present invention relates to a packaging composite film with a laser anti-counterfeiting function. The adhesive resin layer, the laser information layer and the block-shaped alloy layer are sequentially arranged on one surface of the PET polyester plastic film of the flexible substrate from top to bottom. The pattern shape in the laser information layer and the small block area where the alloy layer needs anti-counterfeiting effect are accurately fitted. The method for manufacturing a packaging composite film with a laser anti-counterfeiting function adopts a computer-designed graphic, a text, and an iron-stenciled cable wire processed by electric carving, and the production is completed. Various adhesive resins are coated on the electric carving pattern and the surface of the text, and the oven is passed through the oven. Drying, pressing composite reel forming, with a variety of different properties of the film, coated with adhesive, drying through the drying tunnel after the hot roller temperature, pressure composite compression. The beneficial effect of the present invention is that it is not easy for counterfeiters to counterfeit, and the anti-counterfeit effect can be achieved while achieving aesthetic purposes. In addition, since the anti-counterfeit pattern is generally a partially-dispersed block-like pattern, it is firmly bonded to the substrate and does not easily fall off, and is particularly suitable for shrink packaging films.
[Sovereign Items] 1. A packaging composite film with a laser anti-counterfeit function, characterized in that the surface of one side of a flexible PET polyester plastic film (1) is an adhesive resin layer in order from top to bottom (4) The laser information layer (2) and the small-sized alloy layer (3), the graphic shape in the laser information layer (2) and the alloy layer (3) are precisely nested in a small block area requiring an anti-counterfeiting effect.
