There are five common quality problems of PE film:
Problem 1: the pasting between PE protection film and protected product is not firm.
In the process of transportation and use, the phenomenon of shedding occurs. Mostly is the pressure-sensitive adhesive used in the film is not enough, and there is a possibility that the pressure die machine used by the user is not enough, or the surface is not clean, dust or paint, will affect the paste effect!
If this problem arises, it should be addressed to the cause, to replace sensitive adhesive to increase the pressure of film, or to pay attention to the surface of the material to keep it clean to avoid such problems.
Problem 2: the protective film is in good condition, but the edge of two ends will be up after a period of time.
The main reason for this phenomenon is that the protective film has a large tensile strength in the process of pasting with the protected product. Then it will encounter a high temperature environment, there might have retraction, which occurs mainly in the products of customers in the south. Therefore, PE protective film manufacturer should pay attention to the environmental temperature difference during the production process, and avoid unnecessary surface stretching in the process of pasting.
