Manufacturing method of plastic flexible packaging bag with anti-counterfeiting mark

Abstract

The invention discloses a plastic flexible packaging bag with an anti-counterfeit mark, comprising: a plastic surface layer; a mark attachment layer, which is coated on the lower surface of the plastic surface layer; a variable two-dimensional code mark layer, which is spray printed on the mark attachment layer The lower surface of the layer; the supporting layer, which is sprayed on the lower surface of the variable two-dimensional code marking layer to support the variable two-dimensional code marking layer; the plastic bottom layer, which is located on the lower surface of the supporting layer, and is attached to the plastic surface layer The variable barcode identification layer is attached to the lower surface of the plastic bottom layer and is located at the lower end of the identification attachment layer. The production batch number of the product is printed below the number of the variable barcode identification layer; the protective layer is located on the variable barcode identification layer. The lower surface of the layer is attached to the plastic surface layer. The present invention also provides a manufacturing method of the plastic flexible packaging bag. The anti-counterfeiting mark provided by the present invention is anti-destructive and anti-alteration, and is unique to the goods in the plastic flexible packaging bag, and has better Anti-counterfeiting function.

Description

technical field [0001] The invention relates to a plastic flexible packaging bag. More specifically, the present invention relates to a plastic flexible packaging bag with an anti-counterfeit mark and a manufacturing method thereof. Background technique [0002] At present, the two-dimensional code identification is mostly printed on paper or other hard materials as the carrier to realize the two-dimensional code identification, and the two-dimensional code identification on the plastic bag is mostly sprayed on the surface of the plastic bag. It makes the QR code easy to be destroyed, altered and copied. In order to prevent the two-dimensional code from being copied and affect the consumers to check the authenticity of the product, in recent years, the variable two-dimensional code is emerging, that is, to give each product a unique two-dimensional code, but there is still a problem that the two-dimensional code is copied question. [0003] In view of the above descriptio...
