Surface smearing anti-counterfeit wrapping paper and production method thereof

Abstract

The invention provides a surface-coated anti-counterfeiting wrapping paper and a production method thereof, which belong to the technical field of anti-counterfeiting wrapping paper. The wrapping paper firstly disperses pigments and auxiliary materials through a disperser, and at the same time configures an adhesive to prepare a dispersed glitter fiber latex suspension. The coating is prepared by mixing pigments, adhesives, glitter fiber latex suspension and additives, and the coating is top-coated on the wrapping paper; after the coating is dried, calendering finishing is carried out to obtain the top-coated anti-counterfeit wrapping paper. The method is to add fibers with fiber form and certain reflective properties into the surface layer of the coated wrapping paper, and the traditional printing anti-counterfeiting is difficult to imitate. The identification method is simple, and you can observe the evenly distributed flash points, or the regularly distributed flash points, or the irregularly coded flash points, so as to distinguish the authenticity from the fake ones. The method is simple, practical and beneficial, and achieves the purpose of anti-counterfeiting.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting wrapping paper, in particular to a surface-coated anti-counterfeiting wrapping paper and a production method thereof. Background technique [0002] With the development of economy, the contradiction between counterfeiting and anti-counterfeiting becomes more and more acute. In order to protect the corporate brand, protect the legitimate rights and interests of the market and consumers, it is imperative to take certain anti-counterfeiting measures. However, with the emergence of various new technologies, especially the rapid development of computer graphics processing and digital printing, traditional printing anti-counterfeiting measures are easily broken. Therefore, various new, efficient and low-cost anti-counterfeiting technologies are urgent needs of society and economy. [0003] Now there are many patents in the technical field of anti-counterfeiting wrapping paper. The inventi...

AI Technical Summary

Problems solved by technology

[0004] There are also many anti-counterfeiting papers produced by technologies such as watermarks, security threads, and fluorescent fibers, and various anti-counterfeiting technologies have their own advantages and disadvantages.

For example, the investment in watermark anti-counterfeiting is relatively large. Although the anti-counterfeiting effect of security thread is relatively good, the investment in equipment is also large, and the operation is relatively complicated. Fluorescent fiber anti-counterfeiting technology emits various colors under ultraviolet light, but due to the characteristics of fluorescent fiber itself , it is easy to cause paper disease, which also affects the use of this technology

[0005] In the published patented technology, the anti-counterfeiting of coated packaging paper is either a large investment in equipment or a certain impact on the production of paper sheets, or additional testing equipment is required in the identification process
