<P>PROBLEM TO BE SOLVED: To provide a surface protective film which has preferable attaching property to an adherend, at the same time, can perform stripping beautifully and easily, does not cause contamination of the adherend at all after the stripping, moreover, is not caught by a take-off roller upon the molding and has a combination of superior adhesiveness, molding property and antistatic effect. <P>SOLUTION: The surface protective film comprises an adhesive layer and a substrate layer, wherein the adhesive layer contains styrene type elastomer (i) and linear low-density polyethylene (ii) in a blending proportion of 19/1 to 1/19 by weight ratio, and the linear low-density polyethylene has a bending modulus of 500 MPa or less. Therein, it is preferable that 10 to 30 wt.% of polyether-polyolefin block copolymer (iii) is blended in the adhesive layer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
