<p><P>PROBLEM TO BE SOLVED: To provide a surface protection film made of a polyolefin-based resin which has remarkably few fish eyes, is excellent in dimensional stability, flexibility and transparency, has improved peeling force controllability and delivery performance and is suitable for a surface protection film of a building member such as a synthetic resin plate, a decorative plate, a metal plate and a glass plate and the surface protection film of a liquid crystal display constituting member such as a polarizing plate and a retardation plate. <P>SOLUTION: An adhesive layer is formed on one surface of a base material layer consisting of the propylene-based resin to constitute the surface protection film. The propylene-based resin is obtained, using a metallocene catalyst, by sequentially copolymerizing only propylene or copolymerized propylene and ethylene in a first process and copolymerizing propylene-ethylene random copolymer in a second step. The propylene-ethylene block copolymer has a melt flow rate of 1 to 30g/10 minutes. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
