(1) Generally, supermarket protective films are promoted, but we must not accumulate too much. However, due to a change in temperature during a seasonal transition, protective films should not be exposed to sunlight or moisture. They must be placed in a ventilated area. The best way is to use as much as you want, buy as much as you want, and not have too much inventory.

(2) The quality inspection of the protective film is particularly important. Generally, the PVC plastic of the PE protective film is peeled off from the silicon release test on the coating. However, the adhesive coated side on the back of the film can be tightly pressed together, and then pulled apart. Therefore, it is important to note that the longest stretched adhesive wire between the adhesive and the adhesive should not exceed 0.2 millimeters, In such cases, there is almost no possibility of the protective film degumming during use.
