Abstract
A pressure-resistant paper vessel having highly improved gas barrier property is provided. The paper vessel has at least one layer having a gas barrier film/paper/gas barrier film laminate structure formed by laminating both the surfaces of paper with a gas barrier plastic film having a carbon dioxide gas permeability of not more than 200. The pressure resistance of the paper vessel at normal temperature is higher than atmospheric pressure but not higher than 10 kg/cm.sup.2 G.
