TORETEC™ Surface-Protection Film

A surface-protection film for protecting products from damage during the process, helping to improve productivity.

IT/Industry

TORETEC™ is a surface-protection film that protects the surface of optical films and functional plastic plates, etc. less transcription of adhesive residue.

  • Customers can select the adhesive strength, from low to strong adhesive.
  • A wide selection of widths, lengths and thicknesses are available (extra wide, extra long, etc.).
  • Manufactured on a production line with a proven track record in optical applications.
  • It can be used as process paper in the manufacturing process of various types of optical film for liquid crystals, and additionally as a surface-protection film for plastic plates.

Features

  • Suitable for optical applications
  • Low-adhesive type (resin plates, optical film, polarizing plates, etc.)
  • Medium-adhesive type (heat-resistant and low pollution types available, e.g. for light guide plates)
  • High-adhesive type (types with excellent elongation, etc.)
  • Strong adhesive type (for textured resin plates/optical films, light guide plates, building materials, etc.)
