Gold and silver red miniature laser fluorescent anti-counterfeiting pull wire and its manufacturing method

Abstract

The invention relates to a gold-silver-red miniature laser fluorescent anti-counterfeit pull wire and a manufacturing method thereof, comprising a polyethylene film, a laser film lamination layer, a medium layer, a fluorescent layer, a red light layer, a text protection layer, and a plating layer arranged on the front of the polyethylene film in sequence from inside to outside. Aluminum layer, yellow text layer and pressure-sensitive glue layer; the back of the polyethylene film is coated with a silicone oil layer. The anti-counterfeit pull wire of the present invention passes through multiple processes such as corona, film pressure, plating medium, re-corona, microprinting, printed text protection layer, aluminum plating, printing yellow ink, coating, etc. The structure of the pull wire manufactured by the complex process is also complicated. , improve the production cost, making it difficult for counterfeiters to make fakes. In the manufacturing method, micro-laser engraving plate-making technology is adopted, the font height is 0.01mm, and the printing surface is plated with aluminum firmly. The anti-counterfeiting pull wire of the present invention has the advantages of exquisite design, complex structure and process, high technological content, strong anti-counterfeiting performance, and environmental protection.

Description

technical field [0001] The invention relates to the field of packaging anti-counterfeiting pull wires, in particular a gold and silver red miniature laser fluorescence anti-counterfeiting anti-counterfeiting anti-counterfeiting anti-counterfeiting anti-counterfeiting anti-counterfeiting miniature laser that can be used on transparent plastics and moisture-proof packaging films for cigarettes, food, medicine, electronics, etc. Pull wire and its manufacturing method. Background technique [0002] Cigarettes, chewing gum, optical discs, courier bags and other products, in order to enhance the anti-counterfeiting performance, improve product grades, and make it easy for consumers to unpack, a high anti-counterfeiting pull wire is needed. At present, the existing pull wires on the market simply print anti-counterfeiting text and patterns on the BOPP film substrate, and complete them through simple processes such as gluing. They are only for the convenience of consumers to unpack,...

AI Technical Summary

Problems solved by technology

At present, the existing pull wires on the market are simply printing anti-counterfeiting text, patterns, etc. on the BOPP film substrate, and are completed by simple processes such as gluing. They are only for the convenience of consumers to unpack, without high-tech content and anti-counterfeiting performance.
