(57) [Summary] (Modifications required) [Problem] A stretch film for food packaging with excellent finger restoring property when covering a tray containing food, excellent cutability, heat sealing property of packaging, and good stretch feeling. Offer. The center layer comprises (A) a hard polyolefin resin (3). 0 to 85% by weight, (B) ethylene and α having 3 to 12 carbon atoms A copolymer obtained by polymerizing an olefin with a metallocene catalyst, and having a density of 0.860 to 0.920 g / c. m 3 , melt flow rate 0.5 to 5, and Mw / M 5 to 40% by weight of an ethylene-α-olefin copolymer resin wherein n is 1.5 to 5, and (C) selected from petroleum resins, terpene resins, cumarone-indene resins, rosin-based resins, and hydrogenated resins thereof. A stretch film for food packaging formed of a resin composition containing 3 to 40% by weight of at least one kind of resin. A resin layer such as an ethylene-vinyl acetate copolymer is provided on both sides of the center layer. |
