PET, developed in the early 1970s by DuPont in the USA, was mainly used in industry at the early time, for example, the Coca-Cola bottles we see today are made of PET. PET has advantages of light weight, high strength, good transparency and gas barrier, non-toxic and tasteless, and therefore developed rapidly. Since the 1990s, the production and application of plastic packaging materials has been growing like a spring, and with the maturity of touch technology, PET materials have been used in a variety of LCD screens, which is today's PET protective film!

PET protective film material is transparent and colourless and its surface has been hardened. The surface hardening value of general PET protective film is between 3H-4H. The better the surface hardening, the stronger its wear resistance. Light transmission is also a key property of PET protective film materials, with a general light transmission rate of 90% or more. The higher light transmission not only gives us a good visual effect when using the relevant instruments, but also has a good protective effect on the eyes.

Advantages of PET Protective Film

  • Surface resistance 107-109Ωcm, environmentally friendly, non-toxic, odourless and excellent cleanliness;
  • No electrostatic material migration phenomenon on the product surface.
  • Excellent transparency and can inspect the appearance of optical film in the state of laminated protection material.
  • Low adhesion, small change in adhesion force over time after lamination.
  • Excellent anti-static effect, long-lasting and stable performance.
