In the process of using the transparent PET protective film, the protected finished product will also be directly exposed to the sun. The time may be as long as six months to a year. Generally, the transparent PET protective film will not be fouled during this process, but the performance There may be changes. It even needs to be stuffed in a container and travel across the ocean for a few months. The environment encountered by the transparent PET protective film is actually quite harsh. The transparent PET protective film has excellent mechanical functions, and when used, it is very suitable for the mild tensile strength, elastic modulus, elongation, etc. required by its users. The protective film is lazy to the appearance of the maintained materials, and has an outstanding adhesion function to the maintained materials. During the data transfer and processing, the transparent PET protective film will not warp or fall. The transparent PET protective film has good weather resistance and sticking stability. After a few days or long pasting, the peeling force does not increase significantly, and it is easy to remove. When it is removed, there is no residual glue left on the protected surface and no shadows. After the transparent PET protective film has been used for a period of time, its center performance is outstanding, but its two ends are tilted. The primary reason for this phenomenon is that the transparent PET protective film stretches to a large extent during the posting process of the maintained profile. Fortunately, in the future, there will be unnecessary retraction in a high temperature environment. The problem of transparent PET protective film mostly occurs in the south. Therefore, during the production process of transparent PET protective film, attention should be paid to the impact of environmental temperature differences on the use of the product, and unnecessary external stretching should be avoided during the filming process.
