Abstract

The invention belongs to the technical field of packaging materials, and particularly relates to an anti-counterfeit aluminum foil sealing gasket and a preparation method thereof. The anti-counterfeit aluminum foil sealing gasket comprises a release type imaging layer, a holographic information layer, an aluminum coated layer, a digital layer, a medium layer, an induction layer, an EVA (Ethylene Vinyl-Acetate Copolymer) adhesive layer and a sealing layer which are connected from outside to inside in sequence. The preparation method comprises the following steps: coating the release type imaging layer; designing; performing mold pressing gravure; coating aluminum; washing aluminum; printing; compositely transferring; performing composite sealing. A holographic digital anti-counterfeit means is utilized, integrated holographic printing and digital anti-counterfeit is realized on the aluminum foil sealing gasket, and the anti-counterfeit function of the sealing gasket is increased; a consumer can easily examine and distinguish, all anti-counterfeit characteristics can be tested, an on-site inspection function can be realized, and meanwhile, the non-transferability which cannot be realized by anti-counterfeit marks is realized; the anti-counterfeit aluminum foil gasket is compositely manufactured by using an environment-friendly material, so the environment protection function is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to an anti-counterfeit aluminum foil sealing gasket and a preparation method thereof. Background technique [0002] In the filling or bottle packaging of food or medicine, electromagnetic induction aluminum foil gasket is usually used to seal the seal. Its function is to block air and moisture to extend the shelf life of food or medicine, but it does not have anti-counterfeiting function. Today, when counterfeit and shoddy goods are increasingly rampant, because food and medicine are directly related to human health, anti-counterfeiting of food and medicine has become a top priority. Contents of the invention [0003] The purpose of the present invention is to provide an anti-counterfeiting aluminum foil sealing gasket, which has increased anti-counterfeiting function and improved environmental protection function; the present invention also provides a prep...
