A process for producing a liquid-container material comprising a first thermoadhesive resin film layer, a substrate sheet having a thin-film layer of an inorganic compound, and a paper substrate, comprises the steps of; (a) melt-extruding a thermoadhesive resin from an extruder die to form a first thermoadhesive resin film; (b) cooling said first thermoadhesive resin film obtained in step (a), to a temperature at which the thermoadhesive properties inherent in said film can be retained and at which no crack is produced in the thin- film layer of an inorganic compound when said film is laminated to the substrate sheet having the thin-film layer of an inorganic compound; (c) laminating said first thermoadhesive resin film obtained in step (b), to said substrate sheet having the thin-film layer of an inorganic compound to form a laminate; and (d) laminating said laminate obtained in step (c), to said paper substrate. The first thermoadhesive resin film may preferably be comprised of a non-adsorptive resin layer and a thermoadhesive resin layer. In this instance, the non-adsorptive resin layer is so provided as to be on the outside.
