The difference between the two materials is: PET protective film is a strong glue that brushes the PET material, and he is highly sticky, sticky, low-stick three, with adhesion maintenance effect, its application category is to PET The protective film or double-sided tape is catering to the rear film to find a different product, tearing off the auxiliary material and then migrate to other products, such as mobile phone, etc., etc. have mobile phone screen security.

The PET release membrane protective film brushs the release agent on the PET material, which is light, medium and heavy three. It has the actual effect of delay, and the key application of PET release membrane protective film is to protect the film. , Various adult rubber catering the film, the PET release film protective film, the key has easy tear.

The greater advantage of PET protective film is to be maintained by the production, transportation, storage and application of the product that will not be affected by environmental pollution, etching, scratching, maintaining the original smooth and flexible surface, and enhances the quality of the product. And competitiveness, defect PE protective film and maintenance products are not strong in the middle of the transportation and application of the situation. Therefore, PE will apply OCA electronic optic glue, and the number of customers is the most reflected in the protective film product, and it is not good to remove the glue after removal. The PET protective film and PET release membrane protective film all the same material -PET material, which is only a different main purpose, and most of the difference is not much different.

A small difference is that the PET protective film is thicker, with anti-scraping effect; the PET release film protective film is thinner, no scratch-resistant effect, the maintenance of the three-layer construction, is to be teared. The PET protective film is generally used for the application layer, and the PET release film protective film is a protective layer, which has maintenance effect on the PET protective film.
