Now that society is developing, human beings are progressing, people’s requirements for the quality of life are constantly improving, the production process of PET film is also constantly improving, and our scope of use is also expanding. Next, I will summarize some excellent characteristics of PET film for you to refer to when purchasing.

1.PET film is easy to stick and tear during use, with little change over time, and the increase in peel force is smaller and smaller. The whole product can be used for half a year to a year under sunlight. There will be no pollution and corrosion.

2.PET film has excellent mechanical properties and is very suitable for the tensile strength, elastic modulus, elongation, etc. required by its users. The protective film is inert to the surface of the protected material and has good adhesion to the protected material. The protective film will not warp or peel off during material handling and processing.

3.PET film has good weather resistance and adhesion stability. After a few days or a long time, there is no noticeable increase in peel force and it peels off easily. When peeled off, there is no glue residue on the protective surface and no photo residue.

4.The PET film performed well in the middle after a period of use, but warped at both ends. The main reason for this phenomenon is that in the process of pasting the protected profile, the protective mold is pulled very large. , Unnecessary retraction will occur in high temperature environments.

In addition, in the production process of PET film, attention should be paid to the influence of environmental temperature difference on the use of the product, and unnecessary surface stretching should be avoided during the pasting process.
