Selection of transparent PE film
Mar 25, 2019
When purchasing a transparent PE film, first look at the light transmission degree, it is best to use optical instruments to measure; look at the haze, after each protective film is sequentially pasted, the more clear the color of the computer display screen, the more the haze Small, the smaller the haze, the better the material.
Then look at the antistatic effect of the transparent PE film to see the static electricity. The test method is to prepare the transparent PE film to be tested, pump a cigarette to knock the ash on the table, or get some fine paper scraps on the table, then tear off the PE. The protective film on the top of the protective film, and then peel off the protective film of the silicone layer. When tearing off the PE protective film, the layer will be used to close the soot or paper dust to see if the protective film will adsorb these things to the protection. Whether the degree of adsorption is strong on the silica gel layer of the film. The stronger it is, the higher the static electricity generated by this material is, the worse the material is, and vice versa.
Scratch resistance is also one of the criteria for measuring the quality of transparent PE film. Currently, the scratch-resistant materials on the market are basically the same, and the performance is also good. The test method is to use a qian pen with a hardness of 3H to push 10 times on a transparent PE film at a 45-degree angle of 500 G. Without scratching, it is considered to be up to 3H hardness.
In recent years, many product screen sizes have become larger and larger, and more and more smart machines and capacitive screen applications have increasingly required anti-fingerprint functions for transparent PE films.
