PET polyester film refers to a film made by biaxially stretching a polyethylene terephthalate polymer in the polyester family. Optical grade PET polyester film has high light transmittance, low haze, high brightness, no yellowing, goo
The optical film substrate is generally smooth and defect-free, has high gloss and light transmittance, low haze, and good coating performance. However, if the substrate is apparently flat and free from defects, the contact point betw
The optical film is different from the ordinary protective film or tape. It has a uniform thickness and a dust-free surface and a small crystal point. This imposes higher requirements on the coating technology and requires a film thic
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mai
