[Abstract] the invention relates to this kind of packaging composite film with laser anti-counterfeiting function, On one side of the flexible substrate PET polyester plastic film, from top to bottom, there are adhesive resin layer, laser information layer and small alloy layer. The graphic shape in the laser information layer is precisely nested with the small area of the alloy layer that needs anti-counterfeiting effect. This kind of packaging composite film with laser anti-counterfeiting function is made by using computer to design graphics, text, and iron rolling line treated by electric engraving. All kinds of bonding resins are coated on the surface of electric engraving patterns and text, dried in the oven, and formed by pressing composite reels. It is coated with adhesives, dried in the oven, and then pressed under hot rolling temperature. The beneficial effect of the invention is that it is not easy to be counterfeited by counterfeiters, and it can achieve the anti-counterfeiting effect and the aesthetic purpose at the same time. And because the anti-counterfeiting pattern is generally a small block pattern scattered locally, which is firmly combined with the substrate and is not easy to fall off, it is especially suitable for shrinking the packaging film

[sovereignty item] 1. A packaging composite film with laser anti-counterfeiting function, which is characterized in that: on one side of the flexible substrate PET polyester plastic film (1), from top to bottom, there are adhesive resin layer (4), laser information layer (2) and small piece forming mechanical part and electrical part independently separate gold layer (3), and the graphic shape in the laser information layer (2) is precisely nested with the small piece shaped area of the alloy layer (3) that needs anti-counterfeiting effect
