At present, in the protective film market, the development of pe protective film is still relatively rapid, but there are also many manufacturers that manufacture and produce low-quality protective film in order to obtain shoddy products, which leads to low quality. The protective film of pe is rampant in the market, and how should we test the quality of pe protective film?
Several ways to detect the quality of PE protective film:
1. The pe protective film has a lower crystal point, because the lower the crystal point, the higher the level of the protective film in the overall manufacturing requirements, and the corresponding protective film is higher in quality;
2. The pe protective film must have good weather resistance and stability of the adhesive force. After a period of use, when it is peeled off, the peeling force is not very obvious, and it is very easy to remove it. , After peeling off, there will not be any residual glue on the surface, and there is no phenomenon such as taking pictures;
Third, because the pe protective film is for the material to be protected. It has good adhesion performance, and there will be no warping or falling off in the process of handling the material, or in the process of processing;
Fourth, the pe protective film is mainly inert on the adhesive, and will not have any chemical reaction with the surface of the material to be adhered;
5. The pe protective film is in full compliance with the relevant tensile strength, and the elastic mold and elongation are relatively good.
When we buy pe protective film, more people will first consider the price of the protective film. This is a very serious misunderstanding for the choice of protective film, because only quality assurance can have a price. Accessibility, so it is absolutely impossible to consider price alone, quality is the primary consideration.
