Holographic paper information anti-counterfeit label

Abstract

The invention provides a holographic paper information anti-counterfeit label and belongs to the field of anti-counterfeit labels. The holographic paper information anti-counterfeit label comprises a paper base layer; base paper, an adhesive layer, a coloring layer, an anti-counterfeit code layer and an isolation layer are arranged below the paper base layer from bottom to up in turn; a holographic layer, a printing layer, a variable digital layer and a protection layer are arranged above the paper base layer from bottom to top in turn; the holographic layer can be degraded and cannot be utilized again. According to the holographic paper information anti-counterfeit label, the problem that the anti-counterfeiting is cracked can be solved due to the multiple anti-counterfeiting.

Description

technical field [0001] The invention provides a holographic paper information anti-counterfeiting label, which belongs to the field of anti-counterfeiting labels. Background technique [0002] "Holography" means "all information", that is, compared with ordinary photography, which only records the light and dark changes of objects, laser holography can also record the spatial changes of objects. Holographic anti-counterfeiting is a new anti-counterfeiting technology developed by applying laser holographic technology, also known as laser holographic anti-counterfeiting. Holographic anti-counterfeiting is shot according to the principle of interference method, which must be recorded with high-density photosensitive film, which cannot be shot by ordinary cameras, so the holographic pattern is difficult to be copied; in the whole process of shooting laser holographic pictures, any one of the conditions is different (light, time, etc.) etc.), the effect of holographic anti-count...

AI Technical Summary

Problems solved by technology

[0013] The holographic paper information anti-counterfeit label is divided into upper and lower parts, the upper part is composed of paper base layer, holographic layer, printing layer, variable digital layer, protective layer and scratch-off layer, wherein the degradable holographic layer is used during production , solve the problem that the holographic layer cannot be degraded by hot stamping process, and improve the environmental protection degree of the present invention, and the holographic layer on the laser holographic transfer paper is only the shape or font designed by it, not covering the whole base layer of the paper, so After the transfer of the holographic layer is completed, except for the part covered by the holographic layer, the other parts of the paper base are still in the state of the bare paper base, while the printing layer is printed on the bare paper base, which overcomes the problem that ordinary holographic paper cannot print barcodes. When printing, the non-printing part is also reserved, that is, the base layer of the exposed paper. This part is used to print the variable digital layer. The variable digital layer can print different one-dimensional codes or two-dimensional codes, and then the protective layer and the scratch-off Just attach one side of the layer, scratch off the layer to cover the password printed on the printing layer; the lower part is covered by the upper part, and is combined by glue. Cooperate with the holographic layer for anti-counterfeiting work, and it will be invalid if the upper part is torn apart. The double anti-counterfeiting can effectively prevent the anti-counterfeiting mark and its pasted packaging from being reused and transferred as a whole
