Abstract

The invention relates to pearl holographic anti-counterfeiting paper and a preparation process thereof. The pearl holographic anti-counterfeiting paper sequentially comprises a laser layer, a medium layer, a pearl layer, a glue layer and body paper from top to bottom. The preparation process comprises steps as follows: 1) a molding coating is applied to a transfer basement film; 2) laser information is molded on the molding coating, and a laser information layer is obtained; 3) zinc sulfide is sprayed to the laser information layer, and the medium layer is obtained; 4) the pearl layer is applied to the medium layer; 5) the pearl layer and the body paper are composited through glue; 6) the transfer basement film is peeled. The glue layer is below the pearl layer and cannot affect the pearl effect of the pearl layer; the medium layer is arranged between the pearl layer and the laser layer and can well protect the laser information against interference of the pearl layer, so that the laser information can be presented clearly; the medium layer can protect the pearl layer, the pearl layer covered with the laser diffraction layer cannot weaken, absorb or change incident light rays, and the anti-counterfeiting performance is higher.

Description

technical field [0001] The invention belongs to the field of packaging and decoration materials, and relates to a pearlescent holographic anti-counterfeiting paper and a preparation process thereof. Background technique [0002] Pearl effect packaging materials have always played an important role in the packaging field. In recent years, laser colorful packaging materials have become more and more popular. The laser effect can not only bring visual effects to consumers, but also enhance the appearance of products. Anti-counterfeiting performance. With the improvement of living standards, consumers have higher and higher requirements for packaging materials. Pure pearlescent paper or laser paper as packaging paper can no longer meet the aesthetic requirements of consumers. At the same time, paper with pearlescent and laser effects can improve the beauty and grade of packaging paper, which meets the aesthetic needs of people today. At present, there is no product on the mark...
