PROBLEM TO BE SOLVED: To provide a food packaging stretch film excellent in finger pressing recovery properties at a time of the covering of a food housing tray, also excellent in cutting properties and packaging heat-sealability and good in stretch feeling. SOLUTION: A center layer is formed from a resin compsn. containing (A) 30-85 wt.% hard polyolefin resin, (B) 5-40 wt.% ethylene/α-olefin copolymer being a copolymer obtained by polymerizing ethylene and 3-12Cα-olefin by using a metallocene catalyst and having a density of 0.860-0.920 g/cm<3> , a melt flow rate of 0.5-5 and a wt. average mol.wt. Mw/number average mol.wt. Mn ratio: Mw/Mn is 1.5-5 and (C) 3-40 wt.% at least one kind of a resin selected from a petroleum resin, a terpene resin, a cumarone/indene resin, a rosin resin and hydrogenated resins of them. Resin layers of an ethylene/vinyl acetate copolymer or the like are provided on both surfaces of the center layer.
