Golden, silvery and red miniature laser fluorescent anti-counterfeiting stay wire and method for manufacturing same

Abstract

The invention relates to a golden, silvery and red miniature laser fluorescent anti-counterfeiting stay wire and a method for manufacturing the same. The golden, silvery and red miniature laser fluorescent anti-counterfeiting stay wire comprises a polyethylene film, a laser film pressure layer, a dielectric layer, a fluorescent layer, a red light layer, a text protective layer, an aluminum coated layer, a yellow text layer and a pressure-sensitive glue layer. The laser film pressure layer, the dielectric layer, the fluorescent layer, the red light layer, the text protective layer, the aluminum coated layer, the yellow text layer and the pressure-sensitive glue layer are sequentially arranged on the front surface of the polyethylene film from the inside to the outside, and a silicone oil layer is coated on the back surface of the polyethylene film. The golden, silvery and red miniature laser fluorescent anti-counterfeiting stay wire and the method have the advantages that the anti-counterfeiting stay wire is manufactured by the method including a plurality of processes such as a corona process, a film pressure process, a dielectric coating process, another corona process, a miniature printing process, a text protective layer printing process, an aluminum coating process, a yellow ink printing process and a coating process, the structure of the stay wire manufactured by the complex processes is complex, the manufacturing cost is increased, and the stay wire cannot be easily counterfeited by counterfeiters; a miniature laser engraving plate-making technology is adopted in the method, the heights of texts are 0.01mm, and aluminum can be firmly coated on a printed surface; the anti-counterfeiting stay wire is exquisite in design, complex in structure and process and high in technological content and anti-counterfeiting performance, and is environmental friendly.

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.
