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:
A method for compatibilizing at least two thermoplastic resins each having hydroxyl group(s), with each other, which method comprises reacting at least one of the thermoplastic resins with a boron compound simultaneously with or before mixing of the resins, to form a boric acid ester at least at the boundary of the resins; a resin composition comprising resins compatibilized with each other, obtained by the method; and a laminate whose at least one layer consists of the resin composition.
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.

摘要:
A resin composition comprising: a polyvinyl alcohol; and an inorganic laminar compound having an aspect ratio of not less than 50 and not more than 5000, which has a volume ratio of (inorganic laminar compound/polyvinyl alcohol) in the range of (5/95) to (30/70); and a laminate or laminate film comprising, as at least a portion thereof, a layer or portion (1) comprising such a resin composition. The resin composition, laminate or laminate film may exhibit a good gas barrier property while substantially retaining a good film strength.

摘要:
A laminate, laminate film or shaped article, which includes: a layer of a substance having a gas barrier property; and at least one layer or portion (1) disposed thereon comprising a resin composition comprising a resin and an inorganic laminar compound having an aspect ratio of not less than 50 and not more than 5000. As the gas barrier substance, a metal or oxide, ethylene-vinyl alcohol copolymer, or polyvinylidene chloride may preferably be used. Such a laminate, laminate film or shaped article may exhibit a good gas barrier property which is much higher than that of a conventional plastic material.
