Release film is a type of film with surface separability. Its principle is to do ion treatment on the plastic film, and evenly apply the release agent of silicone oil material to the surface layer of PE, PET, OPP and other film materials. Because the silicone oil in the release film has the characteristics of corrosion resistance, good gloss, tasteless non-toxic, high ignition point and so on, the product has good adsorption and adhesion. Let 's understand a few knowledge points that need to be understood when purchasing release films :

1.Color : The color of the release film can directly reflect the quality of the release film, the silicone oil raw materials used and the processing technology. The release film with better quality has good color and smoothness. The color of the release film is relatively pure and will not be mixed with various colors. The texture and quantity of the paper meet the standard. 

2.Raw materials : The different raw materials used in the release film make its quality very different. There are three main parts of the material structure of the release film, including the base paper substrate, the coating, and the adhesive. Therefore, the difference in the type and amount of the adhesive, as well as the difference in the use of the base paper substrate, will affect the quality and use of the product, as well as various performance indicators. Therefore, when purchasing the release film, you should carefully ask the store 's use of its materials and the type of base paper substrate to choose.

3 Brand and price. The brand, price and after-sales service of the product are all one of the important factors that we must consider. The release film of the well-known brand not only means that its manufacturers can supply the release film for a long time, but also means that its after-sales service is professional, and the abnormalities in the use process can also be solved in time.
