Frosted PC film is a PC film with a matte/semi-matte surface on one side and a matte/semi-matte side on the other. The film has high temperature resistance, good dimensional stability, and good printability without pretreatment. Therefore, the film is used as a multi-layer printing such as surface decoration, floor map, high-performance label and in-mold decoration. Excellent choice to use. The film is suitable for screen printing using traditional solvent-based or water-based inks, UV inks or infrared dry explosion inks, and is easy to thermoforming, embossing, die-cutting, hydroforming and bending processing. The medium sand texture has surface scratch resistance and can be used on the surface of light-emitting devices (LEDs). The current technological improvements have effectively reduced the grain and color differences by 50%, and improved the thickness control.
