<P>PROBLEM TO BE SOLVED: To provide a paper-made material having gas barrier properties that is excellent in adhesion of a resin layer having gas barrier properties and has excellent gas barrier properties. <P>SOLUTION: The paper-made material having gas barrier properties is formed by the steps of: forming a filler layer including at least the one selected from synthetic latexes, synthetic emulsions, water soluble elastomers, and polyvinyl alcohol-based resins on at least a side of base paper or processed paper such that the solid resin content after being dried becomes 0.1-30 g/m<SP POS="POST">2</SP>by a coating method, the wet tensile strength of which the surface is 36 mN/m or more, and the Cobb water absorbency of which surface is 10 g/m<SP POS="POST">2</SP>or less; and forming a gas barrier layer including a polyvinyl alcohol-based resin on the filler layer such that the solid resin content after being dried becomes 0.5-30 g/m<SP POS="POST">2</SP>by the coating method. <P>COPYRIGHT: (C)2013,JPO&INPIT |
