There is also a possibility that the user in the die when the use of pressing machine pressure is not enough, or the profile surface is not clean, dust or paint, etc., affecting the adhesive effect of the gel!
Whether it is color or PET transparent protective film and protected products between the paste is not strong, will appear off phenomenon during the transportation and use, the possibility of viscosity sensitive adhesive is the biggest protective film products used in production is not enough
The protective film intermediate good performance in use after a period of time, but the two wings, the main reason for this phenomenon is a protective film on the protection and profile in paste process, the stretching degree is high, or is in the future with good protective film in high temperature environment, the retraction phenomenon is not necessary this problem, appear in the south of customer products, so the PET protective film in the production process should pay attention to the influence of environmental temperature caused the use of products, to avoid unnecessary tension in the paste process
