The invention provides a laminated film for stretch wrapping including at least three layers, wherein the laminated film has both surface layers containing, as a main component, component (A) which is an ethylene polymer, and has at least one intermediate layer formed of a layer containing, as a main component, a resin composition containing component (B) which is a polypropylene resin having controlled stereoregularity in terms of specific characteristics in an amount of 30 to 75% by weight; component (C) which is a crystalline polypropylene resin having a crystal melting peak temperature of 120° C. or higher in an amount of 20 to 60% by weight; and component (D) which is a petroleum resin in an amount of 5 to 30% by weight. The film of the present invention is excellent in storage stability of feed material pellets, wrapping efficiency, wrapping finish, elastic recovery, bottom sealing property, transparency, etc.
A laminated film for stretch wrapping comprising at least three layers, wherein the laminated film has both surface layers comprising, as a main component, component (A) which is an ethylene polymer, and has at least one intermediate layer formed of a mixed resin layer comprising, as a main component, a resin composition containing the following component (B) in an amount of 30 to 75% by weight:
