Quality problems and treatment methods of protective film

Polymer protective film manufacturers tell us that there are some problems in the production of protective films, and we must work out solutions to these problems. After the protective film has been used for a period of time, the middle part is okay, but the two ends will have wings. The main reason for this phenomenon is that the protective film is stretched to a greater extent during the pasting process with the protected product. At the same time, when encountering a high temperature environment, there is a shrinkage phenomenon. Therefore, in the production process of the protective film, attention should be paid to the influence of the environmental temperature difference on the use of the product, and not to overstretch it.
