A kind of laser holographic anti-counterfeiting composite aluminized film and its production process

Abstract

The invention discloses a laser holographic anti-counterfeit composite aluminum plating film and a production technology thereof. The laser holographic anti-counterfeit composite aluminum plating film comprises a BOPP (biaxially-oriented polypropylene) thin film and waterproof copper plate paper, wherein the BOPP thin film and the waterproof copper plate paper are fixedly connected together by an adhering layer; an upper aluminum plating layer is arranged at the upper end of the BOPP thin film; a laser holographic layer is arranged at the lower end of the waterproof copper plate paper, and a lower aluminum plating layer is arranged at the lower end of the laser holographic layer; the upper aluminum plating layer, the BOPP thin film, the adhering layer, the waterproof copper plate, the laser holographic layer and the lower aluminum plating layer are sequentially arranged from top to bottom. The laser holographic anti-counterfeit composite aluminum plating film has the advantages that a transfer type production technology is adopted, the holographic pattern is directly manufactured on the waterproof copper plate paper, and a plastic release layer is removed; after compounding, the embossing is performed, the copying by a counterfeiter is thoroughly prevented, and the technology is the most advanced anti-counterfeit package production technology; meanwhile, by consuming a relatively small amount of metal aluminum layer, the novel and attractive decoration effect can be reached; the toughness and anti-tearing property of the BOPP thin film are improved.

Description

technical field [0001] The invention belongs to the technical field of packaging material manufacturing, in particular to a laser holographic anti-counterfeiting composite aluminized film and a production process thereof. Background technique [0002] Anti-counterfeiting packaging film not only has anti-counterfeiting function, but also can carry relevant product information. It is colorful, has good surface gloss, high smoothness, non-toxic, no peculiar smell, excellent moisture-proof and water-proof performance, and has good printability, etc. With many advantages, it is widely used in the packaging of cigarettes, beer, food, stationery, gifts, etc. The development of my country's anti-counterfeiting technology and the formation of the anti-counterfeiting industry are the needs of developing a socialist market economy, expanding opening up, developing foreign trade, and promoting my country's commodities to the international market. national, business and consumer interest...
