Laminate film for stretch-wrapping and process for producing the same

A laminate film for stretch-wrapping which comprises an intermediate layer containing from 50 to 95% by weight of at least one member selected from the group (A) consisting of (A-1) an ethylene-.alpha.-olefin copolymer comprising ethylene and an .alpha.-olefin having from 4 to 8 carbon atoms, having an .alpha.-olefin content of from 2 to 20% by weight, and having a melt flow rate of from 0.1 to 5 g/10 min at 190.degree. C., (A-2) a propylene-ethylene-.alpha.-olefin random copolymer or propylene-.alpha.-olefin random copolymer comprising propylene, ethylene and/or an .alpha.-olefin having from 4 to 8 carbon atoms, having an ethylene and/or .alpha.-olefin content of from 4 to 19% by weight and a propylene content of from 81 to 96% by weight, and having a melt flow rate of from 1 to 10 g/10 min at 230.degree. C., and (A-3) a butene-1 homopolymer or butene-1-ethylene copolymer having an ethylene content of from 0.1 to 10% by weight having a melt flow rate of from 0.1 to 10 g/10 min at 190.degree. C. and from 5 to 50% by weight of a hydrogenated block copolymer elastomer which is a hydrogenation product of a block copolymer containing, in the molecule thereof, from 5 to 70% by weight of a polymer block mainly comprising an alkenyl aromatic compound and from 30 to 95% by weight of a polymer block mainly comprising a conjugated diene compound, having laminated on both sides thereof a surface layer comprising from 75 to 95% by weight of ethylene and from 5 to 25% by weight of a vinyl acetate copolymer.
