1. A laminate comprising:
- (a) a layer comprising a substance having a gas barrier property; and
(b) at least one layer which is disposed on the layer (a) wherein said layer (b) comprises 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, said inorganic laminar compound being such that it is swollen or cleft in a solvent, said inorganic laminar compound being selected from the group consisting of a graphite, a phosphoric acid salt derivative compound, a chalcogen compound, a kaolinite series clay mineral, an antigorite series clay mineral, a smectite series clay mineral, and a mica series clay mineral, said resin comprising one selected from the group consisting of polyvinyl alcohol (PVA), ethylenevinylalcohol copolymer (EVOH), polyacrylonitrile (PAN), polysaccharide, polyacrylic acid, and esters thereof.

Abstract
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.
