PROBLEM TO BE SOLVED: To provide stretch films excellent in stretch properties when stretched crosswise and autohesion in wrapping films using polyolefin resins. SOLUTION: This polyolefin stretch film comprises a total of 100 pts.wt. resin component composed of (A) 50-90 pts.wt. ethylene/(meth)acrylic acid/(meth) acrylate ester terpolymer comprising 1-20 mol% (meth)acrylic acid component unit and 1-20 mol% (meth)acrylate ester component unit, (B) 5-50 pts.wt. ethylene/(meth)acrylic acid copolymer comprising 1-20 mol% (meth)acrylic acid component unit, (C) 0-45 pts.wt. carboxylate salt with a metallic ion of an ethylene/α,β- unsaturated carboxylic acid copolymer comprising 1-20 mol%α,β-unsaturated carboxylic acid component unit, (D) 0.5-12 pts.wt. tackifier, and (E) 1-5 pts.wt. anti-fogging agent, and have a stress at 100% elongation in the lengthwise direction of less than 60 MPa.
