Functional Coating Protective Film
Product Featu- res 
. The AR (Anti-Reflection) protective film features high light transmittance (>94%) and low reflectivity (<2%), offering superior performance.
. The AG (Anti-Glare) protective film effectively reduces glare, enhances viewing angles, and minimizes eye strain.
. The HC (Hard-Coating) protective film features a surface hardness of up to 3H on a pencil scale, delivering exceptional scratch resistance.
. A blue light protection film, specially treated with BLC technology, effectively blocks blue light in the 380nm-500nm wavelength range.
. Printable protective film with excellent surface printability
. Stable Adhesion and Good Adherence
Product Use
Scratch-resistant protective film is applied to display panel surfaces (e.g., glass, acrylic), CRTs, mobile phones, and touch screens to prevent scratches during use. Printing-ready protective film ensures secure shipping by protecting products during die-cutting and coding processes.
