Anti-counterfeiting film with random textures

Abstract

The invention discloses an anti-counterfeiting film with random textures. The anti-counterfeiting film comprises a base material layer (1) and an anti-counterfeiting layer (2), wherein the material layer (1) is closely connected with the anti-counterfeiting layer (2), and the anti-counterfeiting layer (2) is an anti-counterfeiting layer having random textures. The anti-counterfeiting film is simple in production process, good in transparency, and small in influence on original color and patterns of a packaging material.

Description

technical field [0001] The invention relates to the field of packaging anti-counterfeiting film materials, in particular to an anti-counterfeiting film with random texture. Background technique [0002] In the chaotic market environment and the social background of increasingly rampant counterfeiting activities, companies that focus on protecting their own brands are paying more and more attention to the anti-counterfeiting features of their products. Based on this demand, various anti-counterfeiting technologies emerge in an endless stream. [0003] With the continuous development of anti-counterfeiting technology, the anti-counterfeiting products currently on the market can be roughly divided into four generations from the perspective of technical characteristics and functional evolution. The first generation is laser anti-counterfeiting or temperature-changing anti-counterfeiting, the second generation is digital anti-counterfeiting, and the third generation It is textur...

Problems solved by technology

[0004] No. 03266092.8 patent provides "an anti-counterfeiting packaging with random anti-counterfeiting identification features" which uses heat shrinkable film to generate random textures during shrink molding to endow materials with anti-counterfeiting properties. When this technology is implemented, heating is required to shrink the film to form random textures. For It is not suitable for packages that cannot withstand heat, so the application field is limited; "Anti-counterfeit Labels with Unlimited Potential Random Images" published in "Label Technology" in August 2014 is to use laminating or papermaking processes in anti-counterfeiting labels. Randomly distributed fibers, random characters and random serial numbers constitute a random pattern to endow the material with anti-counterfeiting information. Fibers, characters or other symbols added by this technology will affect the design of the original pattern and destroy the aesthetic feeling
