Protective Tape
for Optical Use
#6700/#6800/#6900 Series
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.
Conventional production process
PRODUCTION process of co-extruded protect tape
1Our surface protection tapes scacely leave any adhesive residue on the surface of an adherend, since the base and adhesive layers are strongly bonded.
2The solvent-free production process preserves the environment.
Applications
Protecting the surfaces of optical films for such as diffusion and brightness enhance
Characteristics
Strong adhesion type (PP film)
