Protective Tape for Optical Use 6700,6800,6900 Series

Protective Tape for Optical Use  6700,6800,6900 Series

Strong adhesion type

The tapes protect the surfaces of various optical films, such as those for diffusion and brightness enhancement film.

Our products protect optical films in various stages, including production, processing, and transportation.

Features

  • The tapes are manufactured by a co-extrusion production technique that can reduce the adherend contamination caused by adhesive residue.
  • Thanks to our broad lineup of base materials and adhesives, the tapes can protect matte, prism, or any other types of optical film surfaces.
  • The tapes are manufactured in a clean environment.
