Abstract

The invention provides a high-viscosity easy-to-unwind self-adhesive protective film, and relates to the technical field of self-adhesive protective films. The high-viscosity easy-to-unwind self-adhesive protective film comprises an adhesion layer, a middle layer and an anti-adhesion layer, the adhesion layer comprises a thermoplastic elastomer material and tackifying resin, the middle layer comprises polypropylene random copolymer resin, and the anti-adhesion layer comprises high-density polyethylene, low-density polyethylene and anti-adhesion master batch. The high-viscosity easy-to-unwind self-adhesive protective film provided by the invention has the characteristics of high viscosity and small unwinding force, and the product characteristics are far superior to those of similar products in the current market. In the using process, the situations that the self-adhesive protective film is difficult to unwind and prone to wrinkling, and the contact surface with large roughness and lowglossiness is difficult to attach are avoided.

Description

technical field [0001] The invention relates to the technical field of self-adhesive protective film, in particular to a self-adhesive protective film with high viscosity and easy unwinding. Background technique [0002] Protective film is a kind of plastic film used to protect the surface of products from damage during transportation and processing. It can be divided into adhesive film and self-adhesive film according to the viscosity characteristics. [0003] Adhesive film was applied earlier, but due to the limitations of the process and material characteristics, the production process is not environmentally friendly, and there are problems such as easy to pollute the product surface and difficult to tear the film during use. The self-adhesive film is made of macromolecular self-adhesive material, which is prepared by co-extrusion integrated molding technology, which is more environmentally friendly, does not leave glue during use, and is easy to tear. [0004] However, ...
