Production method of embossing laminating release film

Abstract

The invention discloses a production method of an embossing laminating release film. The production method comprises the following steps of placing 100 parts of high density polyethylene, 120 to 180 parts of low density polyethylene, 10 to 30 parts of styrene-isoprene-styrene segmented copolymer, 5 to 15 parts of styrene and butadiene segmented copolymer, 0.5 to 1.5 parts of paraffin, 0.1 to 0.5 part of glycerin, 5 to 10 parts of POE (Polyolefin Elastomer) and 0.3 to 0.8 part of coupling agent into a stirrer to be stirred; performing heating bridging on the mixture through double screws of a laminating machine feeding inlet to obtain a molten mixture; further heating the molten mixture to 220 to 250 DEG C at the position of the feeding screws so as to obtain a fluid mixture and pressurizing the fluid mixture to 5 to 15 Mpa; heating the fluid mixture to 260 to 280 DEG C at the position of a screw outlet to form the fabric shape to be squeezed out. According to the embossing laminating release film, mesh patterns are clear in embossing and unified in depth, distribution lines are uniform, bubbles are not produced between formed embossing laminating release paper and a pressure sensitive adhesive during attachment, and accordingly the use effect is not affected.

Description

technical field [0001] The invention relates to a method for manufacturing an embossed coating release film, 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 canno...

[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 ordinary release film and pressure-sensitive adhesive tape are bonded, air bubbles are likely to form between the two

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
