Abstract

See full text

Provided is a hygroscopic packaging container which eliminates the necessity of filling a moisture absorbent and which has satisfactory working efficiency and is highly effective in moisture absorption. The hygroscopic packaging container is obtained from two gas-barrier multilayer films each comprising a gas-barrier layer and a heat-sealable layer, by stacking the gas-barrier multilayer films so that the surface of one of the heat-sealable layers overlies that of the other and heat-sealing the peripheral parts of the layers, at least one heat-sealable layer of the two gas-barrier multilayer films being a hygroscopic heat-sealable layer.
