SURFACE PROTECTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2010/084832
Kind Code:
A1
Abstract:
Disclosed is a surface protective film used for the purpose of protecting the surfaces of various types of resin plates, glass plates, or metal plates used in the fields of building materials and electrics/electronics. The film is adhered to the surfaces of the same in order to protect the adherends from scratches and/or contamination during storage, transportation, and subsequent processing. More specifically, provided is a surface protective film with which a resin prepared by mixing three components, namely, a styrene-based elastomer or a block copolymer having specific crystalline olefin blocks, an amorphous α-olefin-based polymer, and a crystalline olefin-based polymer, at a specific ratio is used as the resin for the adhesive layer of the surface protective film. Thus, good adhesion is demonstrated, even on an adherend with an uneven surface, and handling ability is excellent.
