The problem of lifting both ends of the PET protective film during use

PET protective film is currently the most common protective film on the market. It has a relatively hard texture and is relatively scratch-resistant. And it will not turn yellow and oily like PVC materials after long-term use. Therefore, it is widely used in digital product protection, automobiles, etc. , mobile phones and other fields.
The two ends of the PET protective film will warp after using for a period of time. The main reason for this phenomenon is that the protective film is stretched to a large extent during the pasting process with the protected profile. Unnecessary shrinkage has occurred. This problem often occurs on products from southern customers. Therefore, during the production process of PET protective film, attention should be paid to the impact of environmental temperature difference on product use, and unnecessary surface tension should be avoided during the pasting process. stretch.
