Embodiment Construction

[0012] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0013] In this embodiment, a PVDC wrapping paper production process with an anti-counterfeiting code comprises the following steps:

[0014] Step 1: Printing decorative patterns on the paper base;

[0015] Step 2: Print the anti-counterfeiting code on the specific position of the decorative pattern by spraying code or thermal transfer;

[0016] Step 3: Coating a layer of water-based varnish on the paper base layer of the printed anti-counterfeiting code;

[0017] Step 4: PVDC coating is carried out after drying the water-based varnish layer.

[0018] The ink used for the decorative pattern is a high temperature resistant 115°C~130°C cooking single-component ink.

[0019] The coating thickness of the PVDC is 6-15 μm.

[0020] The above disclosure is only a preferred embodiment of the present invention, w...

Abstract

Embodiments of the invention disclose a production process of PVDC packaging paper with an anti-counterfeiting code, which comprises the following steps: printing a decorative pattern on a paper base layer; printing an anti-counterfeiting code at a specific position of the decorative pattern in a manner of code-spraying or heat transfer printing; coating a layer of waterborne top oil on the paper base layer with the printed anti-counterfeiting code; drying the waterborne top oil layer, and then coating PVDV. With the invention, colors of the printed pattern and the anti-counterfeiting code are maintained, and abrasion is rare.

Description

technical field [0001] The invention relates to a packaging paper production process, in particular to a PVDC packaging paper production process with an anti-counterfeit code. Background technique [0002] At present, there are many kinds of wrapping papers. Anti-counterfeiting codes on wrapping papers are commonly used to counterfeit. However, due to the structural and process defects of the packaging, the anti-counterfeiting codes and patterns on the wrapping paper after being placed for a long time are prone to discoloration and distortion. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a production process of PVDC wrapping paper with an anti-counterfeit code. It can maintain the color of printed patterns and anti-counterfeiting codes, and is not easy to wear. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a PVDC wrapping paper prod...
