Abstract

The invention discloses a PET protective film which comprises a body and a release film, wherein the body is made of a PET polyethylene terephthalate plastic, the bending strength is larger than 200 MPa, the elasticity modulus is larger than 4000 MPa, the release film is a transparent polyester film, the surface of the body is uniformly coated with the release film, the release force is 20-120 G, the usage temperature is minus 15 DEG C-130 DEG C, and the transparency is larger than 70%. With the adoption of the manner, the PET protective film has the advantages as follows: the PET film is simple in structure, anti-static, anti-scraping, anticorrosion, high-temperature-resistant, impact-resistant, solvent-resistant, good in stability, long in service life, firm and durable, can facilitate large-scale production, and the like. The PET protective film has a wide market prospect in popularization of PET films.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a PET protective film. Background technique [0002] Adhesive tape is one of the commonly used fixing and masking tools in daily life and work. According to its function, it can be divided into high temperature tape, double-sided tape, insulating tape, special tape, pressure sensitive tape, die-cutting tape, etc., which are applicable according to different functions. In different places and fields, PET protective film is one of the commonly used adhesive tapes. However, the existing PET protective film has low hardness, is easy to scratch and wear, and is not conducive to long-term use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a PET protective film. By using PET polyterephthalic acid plastics as the main body of the protective film, its bending strength and elastic modulus are increased, and it is corrosion-resi...
