Optical Protective Film Series

Surface Protection Materials Designed for Cutting-edge Electronics and Optics.​

Optical Hardened Film

The hardened film is subjected to surface hardening treatment on the substrate. The film has good adhesion to the ink and also has a good printing effect.

Good scratch resistance, depending on the application and customer needs, the surface hardness can reach 4H or higher.

This material is widely used in mobile phone screens, touch displays, LCD displays, instrument panels, control panels, membrane switch panels , LCD nameplate, LED, DVD screen protection, surface protection of flat panel displays, in-mold castings for housing processing of household appliances, etc.


* Optical grade PET / PC / TPU / ASF, hardened up to 4H;

* High light transmittance, few crystal points and low coefficient of friction;

* Can do anti-static, printing, anti-fingerprint and other functions;

* 100-level dust-free workshop production, performance can be customized according to customer requirements;
