Plastic bag printing method capable of preventing printing material from permeating

Abstract

The invention relates to the technical field of plastic bag printing, and discloses a plastic bag printing method capable of preventing printing material permeation, which comprises the following steps: S1, debugging printing equipment, keeping the printing equipment in an environment suitable for printing, keeping the temperature of a printing workshop at 18-23 DEG C, and keeping the printing humidity at 55-65%; s2, the plastic bag needing to be printed is treated, low-concentration fluorine gas is introduced, the plastic bag is fluorinated, and therefore the anti-permeation performance of the plastic bag is improved; and S3, ink with low permeability is added, and pattern printing is conducted on the surface of the plastic bag. According to the invention, the plastic bag is subjected to fluorination treatment, so that the permeation of a printing material is reduced, the performance of the plastic bag is changed by treating the plastic bag, and the printing material is difficult to permeate to the other side of the plastic bag during pattern printing, so that the definition of a printed pattern is improved; and printing material permeation can be prevented.

Description

technical field [0001] The invention relates to the technical field of plastic bag printing, in particular to a plastic bag printing method for preventing the penetration of printing materials. Background technique [0002] Plastic bags are bags made of plastic as the main raw material. During the production of plastic bags, almost all custom-made plastic bags need to print Logo patterns. Although the quality of plastic bags lies in the material, the printing quality is good or bad. It directly affects the reputation of plastic bag manufacturers. When the printed pattern is unclear or incomplete, overcoming often terminates the cooperation with the manufacturer. Therefore, the printing of plastic bag patterns plays an important role in the development of the manufacturer. [0003] When printing the pattern on the surface of the plastic bag, the ink is printed on the surface of the plastic bag by a digital printing machine. The surface of the plastic bag is usually treated wi...

AI Technical Summary

Problems solved by technology

[0004] When the surface pattern of the plastic bag is printed, the printing material will often seep through. When the printing material seeps through, it will cause the edges of the picture and text to be unclear and the pattern will be distorted, thereby reducing the quality of the plastic bag, reducing the reputation of the manufacturer, and damaging The development prospect of the manufacturer
