Publication number: 20130177761Abstract: A surface protective film includes a polyolefin base material layer and an adhesive layer. The adhesive layer has hardness (Martens hardness) in a range of 1 N/mm2 to 2.5 N/mm2 and loop tack strength in a range of 0.02 N/25 mm to 0.1 N/25 mm. Accordingly, the surface protective film, even in a form of a rolled product, is easily wound off from a surface of the base material, and can obtain a sufficient adhesive strength to an adherend (e.g., a prism sheet) having a projection on its surface.Type: ApplicationFiled: October 4, 2011Publication date: July 11, 2013Applicant: IDEMITSU UNITECH CO., LTD.Inventors: Yoichiro Kimura, Tomoyuki Kitajima
