Abstract

The invention provides a forward and reverse double two-dimensional code pasting packing bag. A pasting paper is arranged on the packing bag; the lower layer of the pasting paper is a packing bag layer, and the upper layer is a covering film; ink layers are arranged on the forward and reverse two surfaces of the pasting paper; the ink layers and a paper layer of the pasting paper are different in color; the packing bag layer and the covering film are transparent; and the hazes of the packing bag layer and the covering film are lower than 10%. The packing bag has forward and reverse pattern identifications; the haze value ranges of the packing bag and the covering film enable patterns to be effectively scanned; and the packing bag has forward and reverse double two-dimensional codes, and realizes scanning of two information from the same one packing bag in a dismounting state.

Description

technical field [0001] The invention belongs to the field of material packaging, and in particular relates to a packaging bag with front and back double two-dimensional codes and a preparation method thereof. Background technique [0002] At present, there are many products with two-dimensional codes printed on the packaging bags on the market. The main information of the two-dimensional codes is product information, lottery information, enterprise information, or enter the interface of the WeChat official account to participate in evaluation or complaints. CN205023108U discloses a paper-plastic packaging bag with a two-dimensional code, comprising a base layer, which is characterized in that a paper layer, a printed film layer and a waterproof layer are arranged successively on the described base layer, and an anti-counterfeiting code and a waterproof code are printed on the described printed film layer. For the two-dimensional code, the paper layer is partly transparent or...
