    摘要： A linear polyethylene (100 wt parts) of low density of 0.870 to 0.915 g/cc and containing 15 to 50 wt% of components extractable with xylene at 25±1°C and a weight average molecular chain length of 1,000 - 9,000 Ångstroms is mixed with 50-400 parts of an organic or inorganic filler (e.g. calcium carbonate, barium sulfate or talc) and optionally to help dispersion of the filler 0.5-8 parts of a nonionic surfactant (e.g. a glycerine or sorbitan ester of a C12-22 fatty acid) and the mixture is molded into a film. The film is stretched either (a) uniaxially at 30-80°C at a stretch ratio of 1.2-8 in the mechanical direction or (b) biaxially at 40-100°C at a ratio of 1.1-8.0 in the mechanical direction and then at 70-100°C at a ratio of not above 6.0 transversely; optionally a heating setting treatment is then applied. The resultant film formed from the stretched composition is breathable to a high extent and has good strength, touch and appearance.

    摘要： A gas barrier resin composition or its film having very high level gas barrier and moisture barrier properties, which comprises a resin and an inorganic laminar compound having a particle size of 5 µm and an aspect ratio of 50-5,000. Said resin composition or its film can be produced by dispersing an inorganic laminar compound in a resin or resin solution in the state that the inorganic laminar compound is swollen or cloven with a solvent, and removing the solvent from the dispersion, if necessary in the form of a film, while keeping said state.

    摘要： A laminate film for wrapping comprises a layer (A) of an ethylene-α-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; Cx = σ/SCB ave
    wherein σ is a standard deviation of composition distribution (1/1000C), and SCB ave 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 α-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.

    摘要翻译： 用于包装的层压膜包括乙烯-α-烯烃共聚物层（A），其组成分布变化系数（Cx）由下式表示为0.40以下，乙烯含量为50摩尔％以上 和至少一层不同种类; 其中sigma是组成分布的标准偏差（1/1000℃），SCBave是每1000℃（1/1000℃）的短链分支数的平均值。 描述共聚物的制备，以及乙烯或丙烯与α-烯烃或丙烯和乙烯的共聚物，其适合作为不同种类的层。 该膜是安全卫生的，具有低气味，透明度，机械强度，柔软度和低温热封性能优异，因此适用于自动包装，特别是拉伸包装。
