Problems solved by technology

Due to the low price of polyethylene material, the viscosity can be adjusted in a wide range according to different application requirements, so the current vacuum coating protective film base material is mainly made of polyethylene, which is prepared by extrusion molding, injection molding, blow molding and other methods. However, since polyethylene is a non-polar material, poor adhesion often occurs during the application of vacuum coating partial protection
If PE is used as a protective film, it often falls off during use due to weak adhesion between the protected product and the protective film. There is a phenomenon that the middle is pasted well and the two ends are lifted

Description

technical field [0001] The present invention relates to a membrane material. More specifically, the present invention relates to a self-adhesive vacuum-plated electronic protection film. Background technique [0002] The vacuum coating protective film is generally a modified polymer matrix protective film material, which has the characteristics of self-adhesive and thermal shrinkage, and is mainly composed of a polymer substrate and a pressure-sensitive functional material. Compared with surface protection coatings, it has the advantages of convenient use, low price, and reliable effect, and has attracted much attention in the field of material surface protection. Due to the low price of polyethylene materials, the viscosity can be adjusted in a wide range according to different application requirements, so the current vacuum coating protective film substrate mainly uses polyethylene as raw material, and is prepared by extrusion molding, injection molding, blow molding and ...
