To provide a laminated film for stretch packing excellent in appearance, elongation characteristics, strain restoring properties and packing aptitude.
This film has an intermediate layer (A) based on a resin compsn. consisting of 40-20wt.% of a block copolymer (a) consisting of a polymer block of monovinyl substituted aromatic hydrocarbon and an elastomeric polymer block of conjugated diene or a hydrogenated derivative thereof, 20-70wt.% of a polyolefinic resin (b) and 15-35wt.% of a stickiness imparting agent resin (c). Surface layers (B) based on an ethylene/vinyl acetate copolymer resin with vinyl acetate content of 5-40wt.% are laminated to both surfaces of the intermediate layer (A) of which the thickness ratio is 15-40% to the total thickness. The restorable strain quantity of the film is set to 22mm or more.
