A layered polyamide film includes a polyamide substrate; and an adhesiveness-improving layer provided on at least one surface of the polyamide substrate. The adhesiveness-improving layer includes a graft copolymer of a polyester and an acrylic polymer. Another layered polyamide film includes a printing ink layer, an adhesive layer, and a sealant layer sequentially laminated on the adhesiveness-improving layer. A method for producing such a layered polyamide film includes the step of applying an aqueous dispersion of the graft copolymer of the polyester and the acrylic polymer to at least one surface of the polyamide substrate to form an adhesiveness-improving layer and, if necessary, laminating a printing ink layer, an adhesive layer, and a sealant layer on adhesiveness-improving layer.

The present invention provides a multi-layer resin film having excellent oxygen gas barrier properties, particularly even at high humidity, and further having no chlorine content. The multi-layer resin film of the present invention has a biaxially-stretched polypropylene resin film, an adhesive layer formed on at least one surface of the polypropylene resin film, and a polyvinyl alcohol resin layer formed on the adhesive layer, wherein the polyvinyl alcohol resin layer has a value of crystallinity parameter (CP (M//) ⊥) not less than 0.8. The multi-layer resin film of the present invention can be prepared by forming an adhesive layer on at least one surface of an unstretched polypropylene resin film; stretching the film in one direction; forming a polyvinyl alcohol resin layer on the adhesive layer; and stretching the film in another direction perpendicular to the direction of previous stretching.
