PROBLEM TO BE SOLVED: To provide a gas barrier film which is excellent in gas barrier properties under high-humidity atmosphere, has sufficient adhesion strength or film coagulation strength as a packaging material for a long time and has reduced deterioration in laminate strength.SOLUTION: There is provided a gas barrier film which comprises: a resin film substrate; a coating composed of an aqueous coating agent (A) containing a curing agent which is sequentially formed on at least one surface of the resin film substrate; and a coating of at least one layer composed of an aqueous coating agent (B) in which the blending ratio of the curing agent is smaller than that of the aqueous coating agent (A), where the aqueous coating agent (A) has adhesiveness to a gas barrier film and the resin film substrate. |
