Identification code anti-counterfeit printing layer and printing method

Abstract

The invention discloses an identification code anti-counterfeit printing layer, which comprises a film layer, a gravure printing layer, an inkjet identification code layer and a composite inner layerfrom outside to inside, wherein the film layer uses a biaxially stretched polyester film or a biaxially stretched polypropylene film, the printed surface of the film layer is subjected to corona treatment, the gravure printing layer is printed on the inner side surface of the corona-treated film layer, and the composite inner layer uses a composite film formed by gluing an aluminum foil and a polyethylene film, or a composite film formed by gluing an aluminum foil and a casting polypropylene film. According to the present invention, the forward digital inkjet printing process and the forward gravure printing process are combined to achieve the one identification code on one bag, the identification code can be clearly identified on the inner side of the material, the printing pattern on theself-adhesive surface and the paper surface on the existing market can be replaced, and the condition that the identification code cannot be scanned due to damage, pattern defect and other phenomenaduring the use and circulation of the identification code can be effectively avoided.

Description

technical field [0001] The invention relates to a printing method, in particular to an identification code anti-counterfeit printing layer and a printing method. Background technique [0002] In recent years, with the rapid development of the Internet and the application of Internet +, methods such as identifying the authenticity of goods by scanning QR codes, making payments, and linking to the Internet have been widely used in people's lives. Two-dimensional codes are also widely used in identification barcodes on product packaging. However, since the pattern content of gravure printing is determined by the pattern of the printing layout, the identification barcodes on the batch outer packaging products are all the same, and it is impossible to realize one identification code per bag. Moreover, the printed patterns on the surface of self-adhesive and paper are used in the existing market, and the identification barcode is prone to damage and incomplete patterns during use...

Problems solved by technology

However, since the pattern content of gravure printing is determined by the pattern of the printing layout, the identification barcodes on the batch outer packaging products are the same, and it is impossible to realize one bag with one identification code

In addition, the printing pattern on the surface of self-adhesive and paper is used in the existing market, and the identification barcode is prone to damage and incomplete patterns during use and circulation, resulting in the inability to scan the identification code
