PURPOSE:To obtain a multi-layer stretch shrink film for forming a package superior in not only transparency and glossiness but also elastic recovery power and binding power without occurrence of odor of an acetate in stretch/shrink packaging. CONSTITUTION:A core layer is made of an ethylene-propylene copolymer, an ethylene-butene-propylene copolymer, or the mixture thereof. Each outer layer is made of a resin composition obtained by mixing a straight-chain low-density polyethylene having a density of 0.910 to 0.925g/cm<3> and a melt index of 0.5-10g/10min with a straight-chain low-density polyethylene having a density of 0.890 to 0.907g/cm<3> and a melt index of 0.5-10g/10min in a mixing ratio of 11:5 to 5:1. In addition, the total thickness of both the outer layers is 10-90% of the total film thickness. |
