Problems solved by technology

However, due to the high flatness of the coating layer and the poor adhesion between the release agent coating and the coating layer, when the release paper is attached to the film coated with a high-viscosity adhesive, it is easy to cause cracks on the release paper. The release agent coating is taken away by the adhesive with greater adhesion, thus forming a difficult-to-clean release agent coating area on the local surface of the film, destroying the overall purity and consistency of the film

Abstract

Disclosed is a film material for PE coated paper. Raw material formula of the film material is composed of 71.2-90.8% of a polymer, 0.2-1.2% of a lubricant and 9-27.6% of a fogging filler, wherein the polymer is selected from the group consisting of polyethylene, polypropylene, PVC and PET; and the filler is solid particles with the particle size being 3-20 micrometers. A fogging-surface release film with stable release force and good pressure-sensitive adhesive surface fogging effect can be produced, thus reaching low reflection effect of transfer adhesive surface. The production technology is simple, equipment investment cost is low and equipment is convenient to operate.

Description

technical field [0001] The invention relates to a coating material for coating paper, in particular to a coating material for matte coating paper. Background technique [0002] Coated paper, also known as anti-seepage paper, uses a laminating machine to heat-melt the laminating material (such as polyethylene, polypropylene) particles at high temperature and extrude them on the paper (substrate) to form a coating layer, which is then pressed together. , cooling, winding and other processes made of composite paper, the coating layer weight is generally about 20 grams to 25 grams per square meter. The main purpose of coated paper is to make release paper, and release paper is widely used to isolate the glue surface of the tape. The existing release paper is generally coated with a layer of release agent layer (the material used is mainly silicone oil) on the surface of the coated paper to obtain the release paper. However, due to the high flatness of the coating layer and the...
