To considerably inhibit deterioration of contents and preserve the contents for long period by providing a laminate having a gas barrier layer composed of a resin composition having an inorganic layered compound, and bundling a part thereof.
A laminate having a gas barrier layer 3, which is composed of a resin composition having an inorganic layered compound, is provided, and a part thereof is bundled after the contents are packaged. The inorganic layered compound used for the gas barrier layer 3 is an inorganic compound having a layered structure wherein unit crystal layers are put on top ofeach other, e.g. a graphite, a phosphoric acid zirconium compound, a chalcogen compound, a clay mineral or the like. In a laminating method of the gas barrier layer 3, a coating liquid of the resin composition can be used. A resin containing a high hydrogen-bonding resin having a hydrogen-bonding group or an ionic group is preferable used. An anchor layer 2 is formed between the base 1 and the gas barrier layer 3.
