Soft plastic packaging bag with anti-counterfeiting identification and manufacturing method thereof

Abstract

The invention discloses a soft plastic packaging bag with an anti-counterfeiting identification. The soft plastic packaging bag comprises a plastic surface layer, an identification attachment layer, a two-dimension-code-variable identification layer, a supporting layer, a plastic bottom layer, a bar-code-variable identification layer and a protective layer. The identification attachment layer is arranged on the lower surface of the plastic surface layer in a coated mode. The two-dimension-code-variable identification layer is printed to the lower surface of the identification attachment layer in a sprayed mode. The supporting layer is sprayed on the lower surface of the two-dimension-code-variable identification layer to support the two-dimension-code-variable identification layer. The plastic bottom layer is located on the lower surface of the supporting layer and attached to the plastic surface layer. The bar-code-variable identification layer is attached to the lower surface of the plastic bottom layer and located at the lower end of the identification attachment layer. The batch number of a product is printed below the number of the bar-code-variable identification layer in a sprayed mode. The protective layer is located on the lower surface of the bar-code-variable identification layer and attached to the plastic surface layer. The invention further provides a manufacturing method of the soft plastic packaging bag. The anti-counterfeiting identification arranged on the soft plastic packaging bag is resistant to damage and obliterating and is unique relative to the product in the soft plastic packaging bag, and meanwhile the good anti-counterfeiting function is achieved.

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...
