What does weather resistance of transparent PET protective film mean?

During the use of transparent PET protective film, the finished product protected will also be directly exposed to the sun, which may last for half a year to one year. In this process, the transparent PET protective film will not be polluted, but its performance may change. It even needs to stay in the container and spend several months drifting across the sea. The environment that transparent PET protective film encounters is actually quite harsh.

Transparent PET protective film has excellent mechanical function, which is very suitable for the tensile strength, elastic modulus, elongation, etc. required by users. The protective film is lazy to the appearance of the data to be maintained, and has outstanding adhesion function to the data to be maintained. In the process of data transfer and processing, the transparent PET protective film will not rise or fall.

Transparent PET protective film has good weather resistance and adhesion stability. After several days or long application, the peeling force is not significantly increased, and it is easy to remove. When removed, there is no residual glue left on the protected surface, and there is no residue.

After being used for a period of time, the transparent PET protective film will show outstanding performance in its center, but its two ends will be turned up. The main reason for this phenomenon is that the transparent PET protective film has a large degree of tension during the pasting process of the profile being maintained. After being pasted, it will show unnecessary retraction in case of high temperature environment.

The problem of transparent PET protective film often occurs in the south. Therefore, during the production process of transparent PET protective film, attention should be paid to the impact of environmental temperature difference on product application, and unnecessary surface stretching should be avoided during the film pasting process.
