Differences between PET release film and PET protective film

The main difference between the two materials is that PET protective film is a kind of super glue with different viscosity, which is divided into three types: high viscosity, medium viscosity and low viscosity. It has adhesion maintenance effect. Its application scope is to cut the film into different product shapes after meeting the requirements of pet protective film or double-sided tape, tear off the auxiliary materials and then transfer them to other products, such as mobile phones, computers, etc.
PET release film protective film is coated with release agent on PET material. It is divided into light, medium and heavy release forces, and has the actual effect of degumming. The key application of PET release film protective film is to meet the needs of protective film cutting, and various adhesive tapes meet the needs of film cutting. PET release film protective film is an auxiliary material, which is easy to tear.
The great advantage of PET protective film is that the products to be maintained will not be polluted, etched, scratched by the environment in the whole process of production, transportation, storage and application, and the original smooth, soft and bright surface will be maintained, thus improving the quality and competitiveness of the products. The defective PE protective film is not firmly stuck with the products to be maintained, which will fall off in the whole process of transportation and application. Therefore, PE will apply OCA electronic optical adhesive, and the most common problem is the problem of opening the protective film. It is not easy to remove the adhesive after it is removed. PET protective film and PET release film protective film are all the same material - PET material, which is only used for different main purposes, most of which are not much different.
One small difference is that the PET protective film is relatively thick and has anti scraping effect; The protective film of PET release film is relatively thin and has no actual scratch resistance effect. It is used for maintenance of three-layer structure and needs to be torn off. PET protective film is generally used as application layer, and PET release film protective film is used as protective layer, which has maintenance effect on PET protective film.
