Title:
SURFACE-PROTECTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2000/044841
Kind Code:
A1
Abstract:
A surface-protective film comprising a polymer film and formed on one side thereof a pressure-sensitive adhesive layer or a release layer, in which the polymer film has a maximum strain in the main orientation axis of 10 degrees or less. The surface-protective film is suitable for protecting a surface of, e.g., a synthetic resin plate, especially for protecting a surface of a constituent member of a liquid-crystal display, such as a polarizing plate or phase plate. This is because there is no need of peeling off the surface-protective film in the inspection of the protected product, i.e., the film brings about satisfactory inspection efficiency, and because the film is inexpensive.
