    摘要: A laminate film for wrapping which comprises a layer comprising (A) an ethylene-.alpha.-olefin copolymer having a coefficient of variation of composition distribution (Cx) represented by equation shown below of 0.40 or less and having an ethylene content of 50 mol % or more and at least one layer of a different kind;Cx=.sigma./SCB.sub.avewherein .sigma. is a standard deviation of composition distribution (1/1000 C), and SCB.sub.ave is an average of the number of short chain branchings per 1000 C (1/1000 C).The film is safe and hygienic, less odorous and excellent in transparency, mechanical strength, softness, and low-temperature heat sealing properties and is therefore suitable to automatic wrapping, particularly stretch-wrapping.
