To provide a paper container for a liquid, which prevents cracks or the like from occurring in a vapor-deposited film of an inorganic oxide, such as a silicon oxide and an aluminum oxide, for forming a transparent barrier film as a barrier material, which generates none of baking pinholes or the like, which is thereby excellent in barrier properties for checking oxygen gas, water vapor, and the like from permeating through the vapor-deposited film, which avoids sealing failure, liquid leakage, and the like to be accompanied by the generation of the pinholes, which prevents the deterioration or the like of contents, and which is excellent in shelf stability, storage properties, etc.

A laminated material is formed of at least such layers as the outermost layer, a paper base material, an adhesive layer consisting of a resin layer which is formed by melting and extruding an ethylene/unsaturated carboxylic acid copolymer, or an ethylene/esterified unsaturated carboxylic acid copolymer, at 300°C or below, a barrier layer formed of a vapor-deposited film of an inorganic oxide and a gas barrier coated film, both being provided on one of faces of a base film, and an innermost layer consisting of an ethylene/alpha olefin copolymer layer prepared by the polymerization using a metallocene catalyst, wherein each of the layers are laminated on one another in the order named. The paper container for a liquid is formed by making a box from the laminated material thus prepared.
