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.

Resin composition laminate and laminate film

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 (,) 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.

Resin composition, laminate, and laminate film

Bio-degradable resin composition, film and shaped article

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.
