Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a hot-melt composite nuclear track microporous anti-counterfeiting film, which adopts acrylic acid with a thickness of 1 to 3.5 microns on the non-irradiated surface of the plastic nuclear irradiation film. The measures of ester and dry compound protective film are used to strengthen the tensile strength of microporous membrane, which not only solves the problems of broken film, wrinkle and micropore blockage in the use of microporous membrane, but also opens up the anti-counterfeiting of microporous membrane.

Embodiment Construction

[0023] The separate hot-melt composite nuclear track microporous anti-counterfeiting film of the present invention includes a plastic nuclear irradiation film, and the material used for the plastic nuclear irradiation film is polypropylene, polyester or polycarbonate film. The non-irradiated surface is coated with 1-3.5 micron thick acrylate, the 180° peel strength of the acrylate is controlled at 5N / m-20N / m, and the 10-25 micron thick plastic film is dry-coated on the acrylate layer As a protective peeling film layer, the plastic protective film is made of polyester or polycarbonate material. The plastic protective film is not only a hot-melt heating surface during hot-melt lamination, but also a protective layer to prevent the plastic nuclear radiation film from being damaged by overheating. , and the plastic protective film can be separated from the plastic core protective film after hot-melt lamination, so that the anti-counterfeiting information can be exposed.

Abstract

A nuclear track micro-porous false proof film of hot-melten composite type is prepared for coating acrylate resin in thickness of 1-3.5micro on non-radiated surface of plastic nuclear radiated film, controlling a stripping intensity of acrylate resin to be 5-M / m-20N / m at 180deg.c, dry-plating plastic film in thickness of 10-25 micro on surface of acrylate resin layer and using dry-plated plastic film as stripping-protection layer.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technology, in particular to a hot-melt composite nuclear track microporous anti-counterfeiting film. Background technique [0002] In commodity economic activities, counterfeit commodities and bills often appear, which bring great harm and loss to users and consumers. In order to prevent the harm of counterfeit goods and bills, people adopt various anti-counterfeiting films to carry out anti-counterfeiting. The anti-counterfeiting films that appear at present generally use anti-counterfeiting patterns printed on special paper and special inks, or anti-counterfeiting patterns made of special heat-sensitive materials, or anti-counterfeiting patterns made by holographic laser photography technology. And equipment is easy to obtain, so it is easy to forge, but it is difficult to achieve anti-counterfeiting effect; now there are many types of anti-counterfeiting label products produced by applying ...
