Embossing release film

Abstract

The invention discloses an embossing release film. The embossing release film comprises a polyester film layer and a spraying film coating layer with which the surface of the polyester film layer is coated. The surface, back on to the polyester film layer, of the spraying film coating layer is provided with an embossing pattern area, and the surface of the embossing pattern area is coated with an organosilicone release agent layer. The spraying film coating layer comprises, by weight, 100 parts of high-density polyethylene, 120-180 parts of low-density polyethylene, 10-30 parts of styrene-isoprene-styrene triblock copolymers, 5-15 parts of segmented copolymers of styrene and butadiene, 0.5-0.15 part of paraffin, 0.1-0.5 part of glycerinum, 5-10 parts of POE and 0.3-0.8 part of coupling agent, wherein the POE is a high polymer of ethylene and butane or a high polymer of ethylene and octylene. Netted grain formed through the embossing release film is clear and uniform in depth, and distribution lines are uniform. When formed embossing spraying film release paper is pasted on a pressure-sensitive adhesive, no bubble will be generated between the embossing spraying film release paper and the pressure-sensitive adhesive, and therefore the use effect will not be affected.

Description

technical field [0001] The invention relates to an embossed 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 cannot be used by high-end products use...

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
