Embossed coated release paper

Abstract

The invention discloses an embossed coated release paper. The surface of a coated layer opposite the polyester film layer is provided with an embossed pattern region; the surface of the embossed pattern region is coated with an organosilicon release agent layer; and the coated layer is composed of the following components in parts by weight: 100 parts of high-density polyethylene, 170 parts of low-density polyethylene, 13 parts of styrene-isoprene-styrene block copolymer (SIS) and 9 parts of styrene-butadiene-styrene block copolymer (SBS). The release agent layer and polyester film layer of the embossed coated release paper have higher binding force, and the residual adhesion rate is greatly improved.

Description

technical field [0001] The invention relates to an embossed film-coated release paper, which belongs to the technical field of release materials. Background technique [0002] Usually the release film refers to the coating of silicone oil on the surface of the polyester film to play the role of anti-sticking; the surface of the release film can have a smooth surface and a matte surface, but the pressure-sensitive adhesive tape made of this traditional release film When using label tape, the beautification effect of the glue surface is not ideal. When the ordinary release film is attached to the pressure-sensitive adhesive tape, air bubbles are likely to form between the two. Using embossed release paper, although it can achieve the effect of air bubbles, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the glue surface, and there are paper scraps on the edge after die-cutting, so it cannot be used by high-end ...

Using embossed release paper, although it can achieve the effect of air bubble removal, but because the release paper is easy to absorb water, the tear resistance is not high, it is difficult to observe the rubber surface, and there are paper scraps on the edge after die-cutting, so it cannot be used by high-end product used
