Pet protective film in the use of two common problems

1.PET protective film will have wings on both sides after being applied for a period of time. The key reason for this phenomenon is that the protective film has a high level of extension in the whole process of pasting with the maintained aluminum profile. After being pasted, unnecessary shrinkage occurs in the high temperature natural environment. This problem often occurs in the products of customers in the southern region, therefore, PET protective film should pay attention to the harm of natural environment temperature difference to product application during processing, and prevent unnecessary surface Rashin during the whole process of pasting.

2.PET protective film is difficult to peel off. When the aluminum profile product is peeled off at the end of installation, the protective film cannot be peeled off reasonably. In the final analysis, there are 2 probabilities. The 1 is that the commonly used sensitive adhesive for protective film products is not the special sensitive adhesive for protective film. In that case, the protective film will naturally have a good actual effect when pasting, but it will be very difficult when peeling off, this is also a common problem in the production of protective films by some illegal PET protective film product manufacturers. There is also a probability that the material used in the protective film master tape is too soft to bear the tensile force during peeling, and the phenomenon of cracking occurs during peeling. It is a difficult problem for customers.
