PROBLEM TO BE SOLVED: To obtain a wrap film good in safety, flexibility, sticking property, cutting property, etc., and suitable for heating with an electronic oven, and a cold or a frozen storage by using a resin composition consisting of a polypropylene-based resin and a specific ethylene-α-olefin copolymer. SOLUTION: This wrap film is formed from a resin composition containing (A) 50-98 pt.wt. polypropylene-based resin having preferably 0.5-20 g/10 min (ASTM D1238) and 0.89-0.91 g/cm<3> density and (B) 2-50 pt.wt. ethylene-α-olefin copolymer having <=0.90 g/cm<3> density. By containing 1-50 pt.wt. high pressure polyethylene and 1-30 pt.wt. polybutene based on 100 pts.wt. resin composition, melt physical properties thereof can become easily controllable and adhesion property thereof can be increased further.
