    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.

    摘要: The disclosed composition contains a biodegradable resin, and an inorganic laminar compound having an aspect ratio of not less than 50 and not more than 5000. A biodegradable film or shaped article includes, as at least a portion thereof, a layer (1) found from this biodegradable resin composition. The biodegradable resin composition, film or shaped article can exhibit a good gas barrier property while substantially retaining the desired biodegradability. Therefore, it can considerably contribute to the maintenance or protection of a terrestrial environment such as the disposal of trash or rubbish, or plastic wastes; and the reduction in the amount of wastes in landfills.

    摘要: A gas barrier resin composition or its film having very high level gas barrier and moisture barrier properties, which includes at least a high hydrogen-bonding resin and a non-film-forming inorganic laminar compound having a particle size of 5 .mu.m and an aspect ratio of 50-5,000. The resin composition or its film can be produced by dispersing a non-film-forming inorganic laminar compound in a high hydrogen-bonding resin or resin solution in such a state that the non-film-forming 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 maintaining the state.
