Two common problems in the use of Pet protective film
1. The PET protective film will wing 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 during the whole process of pasting with the maintained aluminum profile. Later, in the high temperature natural environment, unnecessary shrinkage appeared. This problem mostly appeared on the products of customers in the south. Therefore, the PET protective film should pay attention to the hazards of the natural environment temperature difference to the product application during the processing process. Prevent unnecessary surface pulls during the whole process.2. The PET protective film is difficult to peel off. When the aluminum profile product is installed and the peeling is carried out, the protective film cannot be peeled off reasonably. In the final analysis, there are two probabilities. First, the protective film products commonly used in sensitive adhesives are not protective Film-specific sensitive adhesive, if that is the case, the protective film will naturally have a good effect when it is pasted, but it will be very difficult to peel off. This is also the most common way for some illegal PET protective film product manufacturers to produce protective film. 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 cracking occurs during peeling. It is a very difficult problem for customers.
