Manufacturing method oflaser fluorescent anti-fake tear tape with both sides in gold or silver stamping

Abstract

The invention relates to a laser fluorescent anti-fake tear tape with both sides in gold or silver stamping and a manufacturing method thereof. The laser fluorescent anti-fake tear tape comprises a polyethylene film, a gold face layer and a laser fluorescent face layer; the gold face layer and the laser fluorescent face layer are respectively composited on two sides of the polyethylene film; the gold face layer comprises a front stamping glue layer, a front aluminized layer, a gold-stripe ink layer, a front gloss oil protective layer and a pressure-sensitive adhesive layer; the laser fluorescent face layer comprises a back stamping glue layer, a red fluorescent layer, a laser film pressure layer, a back aluminized layer, a transparent character layer, a back gloss oil character-protective layer and a silicon oil layer arranged from inside to outside sequentially. Two rolls of PET polyester film are used as transfer film; the gold-stripe ink layer, the aluminized layers, the transparent character layer, the laser film pressure layer and the red fluorescent layer which are preprinted and coated on the PET polyester film are transferred to the front side and the back side of BOPP (biaxially-oriented polypropylene) film through the synchronous front-and-back side composite process, so that technological content and anti-fake performance of the anti-fake tear tape are improved.

Description

technical field [0001] The invention relates to the field of packaging anti-counterfeiting technology pull wires, in particular to a front and back hot stamping that can be used on transparent plastics and moisture-proof packaging films for cigarettes, cartons, electronics and other products for anti-counterfeiting, decoration and convenient tearing of packaging films. A method for manufacturing a gold and silver laser fluorescent anti-counterfeit pull wire. 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 are simply printed 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, wi...

Problems solved by technology

At present, the existing pull wires on the market are simply printed 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, and Composite technology cannot be used to accurately composite the front and back of BOPP film
