Lumirror™ high transparency (optical clear) grades are PET films with high transparency, low haze, and excellent smoothness thanks to their particle-free raw material design.

Lumirror™ high transparency grades feature an adhesive promotion coating that is the result of Toray's many years of film and polymer research, experience, and technology, giving the film excellent scratch and contamination control.
Thanks to these strengths, it is used in various applications, including for touch panels, window films, automobiles, and more.
We can offer the optimal grade for the application as well as customize the film to meet your needs, including adhesive promotion treated on both sides, adhesive promotion treated on one side, low oligomer grades, etc.
