Flexible packaging bag with traceability and anti-counterfeiting functions and preparation method thereof

Abstract

The invention relates to a soft packing bag with source tracing and anti-counterfeiting functions and a preparation method thereof, and belongs to the field of anti-counterfeiting package labeling identification. The soft packing bag comprises a bag body formed by connecting a frontal PET layer with a back PET layer; a printing layer (2), a white ink layer (3), a local white ink layer (4), a two-dimensional code II (5), a curing glue layer (6) and a PE heat sealing film layer (7) are arranged below the back PET layer (1) of the bag body in sequence; the printing layer (2) is provided with a two-dimensional code I (11); the local white ink layer (4) is opposite to the two-dimensional code I (11); and the two-dimensional code II (5) is opposite to the local white ink layer (4). The soft packing bag is high in logo anti-counterfeiting degree and not liable to be simulated, can realize such functions source tracing, anti-counterfeiting, integration and prize claiming of products, and can promote the credibility on brands; and the preparation method is scientific, reasonable, simple and feasible.

Description

technical field [0001] The invention relates to a flexible packaging bag with traceability and anti-counterfeiting functions and a preparation method thereof, which belongs to the field of anti-counterfeiting packaging labels. Background technique [0002] With the continuous development of society, food safety scandals that are constantly being exposed have stimulated people's nerves, and food safety issues have gradually become the focus of everyone's attention. An anti-counterfeit code is set on the outside of the soft package to facilitate product traceability, anti-counterfeiting and redemption points, etc. However, the anti-counterfeit codes currently used are all uniform anti-counterfeit codes, which not only cannot be traced back to the source, but are also easy to be imitated, and the product is counterfeited. The anti-counterfeiting strength is weak Low. [0003] Facing the complex market situation, consumers most want to know the quality and safety of products an...
