摘要： A wrap film comprising a thermoplastic resin composition and having a longitudinal direction elongation at break of less than 100% and a longitudinal direction strength at 5% elongation of 150 cN/10 mm or less is disclosed. The thermoplastic resin composition comprises a polypropylene resin and at least one resin having a flexural modulus of 100 MPa or less selected from an ethylene-propylene rubber and an ethylene-α-olefin copolymer having 4 or more carbon atoms in the α-olefin unit.

摘要： The wrapping film of the present invention has a sticky surface, convexities, and flat portions of film disposed between the convexities on at least one side, and comprises at least one agent selected from the group consisting of a surface active agent, an adhesive agent, and an oily agent. The wrapping film has a shear adhesion strength of at most 400 cN/25 cm2 when measured subsequent to bringing said sticky surface into contact with a glass surface having a surface roughness of from 0.7 to 1.5 nm under a pressure of 4 Pa, a shear adhesion strength of at least 700 cN/25 cm2 when measured subsequent to bringing said sticky surface into contact with said glass surface under a pressure of 4 kPa, and the ratio of the height of the convexities to the thickness of the flat portion ranges from 0.03 to 1.67. The wrapping film may also have a surface with a roughness and waviness (Ra′) of at least 40 nm as measured in a non-extended state, and an elongation at break of at least 10%.
