Abstract: A multi-layered article molded according to the present invention has in its cross-section a triple-layered structure consisting of two surface layers and a core layer interposed between said surface layers, said triple-layered structure being injection molded in a single shot from two kinds of thermoplastic synthetic resins to be formed into the surface and core layers, respectively, said core layer having a thickness less than one half of the entire thickness of said article.

Abstract: There are disclosed films for stretch wrapping which comprise an olefin polymer, preferably a specific ethylene-vinyl acetate copolymer (referred to as "EVA copolymer" hereinafter) and specific polyalkylene ether polyols and non-ionic surfactants of fatty acid and polyhydric alcohol ester derivatives and which have suitable orientation expressed by heat shrinkage and excellent elastic recovery, by which excellent mechanical strength, wrapping finish, optical characteristics and preservability of the goods, especially fresh foods are attained. Method for producing said films is also disclosed. These films are suitable also for wrapping by automatic wrapping machines.
