摘要： A laminate film for wrapping comprises a layer (A) of an ethylene- alpha -olefin copolymer having a coefficient of variation of composition distribution (Cx) represented by the equation 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; wherein sigma is a standard deviation of composition distribution (1/1000C), and SCBave is an average of the number of short chain branchings per 1000C (1/1000C). The production of the copolymer is described, and copolymers of ethylene or propylene and an alpha -olefin or of propylene and ethylene which are suitable as the different kind of layer. The film is safe and hygienic, has low odor and excellent in transparency, mechanical strength, softness, and low-temperature heat sealing properties and is therefore suitable to automatic wrapping, particularly stretch-wrapping.

摘要： An oxygen absorbing sheet is obtained by molding a resin composition comprising from 15 to 70% by weight of a thermoplastic resin and from 30 to 85% by weight of an oxygen absorbent into a sheet having a thickness of from 10 mu m to 5 mu m and stretching the sheet at least uniaxially at a stretch ratio of from 1.5 to 8.0. The absorbent is an iron powder, preferably of particle size 0.1-100 mu m and preferably with a halide, carbonate, sulfate or hydroxide in amount of 0.1 to 10 wt % of the total absorbent. The resin is preferably a copolymer of ethylene and a C4-12 alpha -olefin, a copolymer of ethylene and/or butene-1 and propylene, a copolymer of ethylene and vinyl acetate and/or a (meth)-acrylic ester, or a metal salt of a copolymer of ethylene and acrylic acid. The composition can be shaped by extrusion or calendering and stretched by roll or tubular stretching uniaxially or biaxially (successively or simultaneously). The oxygen absorbing sheet is easy to handle, and its oxygen absorption capacity is controllable as desired.
