Anti-fake label stick with hidden variable information, and preparation method thereof

Abstract

The invention relates to an anti-fake label stick with hidden variable information. The anti-fake label stick comprises a paper layer 5. A surface printing layer 4, a data printing layer 3 and a covering layer 1 are arranged on one side of the paper layer 5 orderly from inside to outside, and a glue layer 9 is arranged on the other side of the paper layer 5. The anti-fake label stick is characterized in that a plasticizing layer 6, a dielectric layer 7 and a hidden information layer 8 are arranged orderly between the paper layer 5 and the glue layer 9. The data printing layer 3 in the anti-fake label stick has variable information codes. The anti-fake label stick with the hidden variable information is not easily replicated and has good anti-fake effects. The anti-fake label stick provided in the invention is applicable to various hang tags, securities, product qualification certificates and various certificates.

Description

technical field [0001] The invention relates to an anti-counterfeit label sticker and a preparation method thereof.

AI Technical Summary

Problems solved by technology

Since this kind of anti-counterfeiting label only has a surface printing layer, a data printing layer and a covering layer, there are few layers, the production process is simple, it is easy to imitate, and it is difficult to achieve the purpose of anti-counterfeiting

Although smart codes are also set in the data printing layer of some of the above-mentioned traditional anti-counterfeiting label stickers, this smart code is the same in the same batch of goods and cannot be changed.

Since this kind of smart code is the same in the same batch of goods and cannot be changed, it is easy to imitate by using computer programs.

In short, the above-mentioned traditional anti-counterfeiting labels are easy to imitate, and the anti-counterfeiting effect is poor
