Problems solved by technology

[0002] In the existing process, the pet film is usually peeled off after the paper is compounded. After the pet film is used to transfer the coating to the paper, the moisture on both sides of the paper is unbalanced, and the transfer coating also has a certain shrinkage force, resulting in printed products. Curl occurs

Abstract

The invention provides a process for preventing printing paper from curling. The problem that traditional printing paper is prone to bending is mainly solved. According to the process, after a pet film and the paper are compounded, the back surface of the paper is coated with water-based acrylic gloss oil before stripping the pet film, the water-based acrylic gloss oil is dried to 0.6 g and then cured, and the pet film is stripped after curing is completed, so that the function of preventing the paper from curling is achieved.

Description
