Q:What are the unique properties of PET protective film?

Property 1: Highly adhesive, fairly sticky and anti-solvent. When used in the normal temperature environment, the sidelines of the film stay straight and no glue remains. Use: Apply to decoration and ordinary industrial sheltering. Property 2: Excellent whether resistance. Apply to use at temperature below about 150℃. No residual glue. And the boundary of color separetion is clear. Use: Apply to car color covering and industrial machinery painting. Property 3: Special PET material with high tensile strength as well as acid and alkali-resistance. No permeation and no residual glue. Use: Apply to spray paint at high temperature. The film is made from sprcific materials, making it resistant to high temperature and environmental friendly. Once coated, the film will not fall off. And no glue will remain.
