Glue problem of PET protective film


The PET protective film in the protective film, I believe that everyone will not be unfamiliar to see it, because there are related articles in this website, and it has been introduced, so this conclusion will be reached. Below, we will continue to do so, because we have not yet fully understood it, so as to speed up the learning so that everyone can reach the target as soon as possible.


1. How to accurately distinguish the two films from PE film and PET film? In addition, which kind of glue is used on the PET protective film?


PE film and PET film, how to accurately distinguish the two films, in fact, is very simple, as long as they start from the two types of glue on the surface, as well as the molding method. On the protective film of PET protective film, it is mostly used for silica gel. Although acrylic glue can also be used, it is not widely used as silica gel.


2. What are the instructions on the PET protective film?


The instructions on the PET protective film are mainly:


Different PET protective film surfaces sometimes require different tackiness. Therefore, in some processing steps, it is critical because it determines the surface tackiness of the protective film. In addition, in the thickness of the protective film, it is also necessary to properly match the surface viscosity, so as to ensure the good use of the PET protective film.


3. PET protective film glue yellowing, what is the reason?


If the PET protective film is yellowed, then the specific cause is caused by its unstable quality, and this is also the main reason. Therefore, if you want to solve it completely, then you should use anti-yellowing silicone glue. In addition, in the storage environment of the PET protective film, it is also appropriate to do so. Also, pay attention to some matters, such as humidity should not be too large or too small, and there should be no sulfide in the environment.
