Abstract

Disclosed are a biaxially stretched polyamide resin film having gas barrier properties and a process for producing the biaxially stretched polyamide resin film having gas barrier properties. In this film, a gas barrier coat layer is formed on at least one side of a biaxially stretched polyamide resin film, the thickness of the gas barrier coat layer is 0.5 to 5 μm, and the amount of the extracted monomer in the polyamide resin film is 0.1% by mass or less. The production process includes, in the order of description, the steps of removing the monomer in an unstretched polyamide resin film, biaxial stretching, and laminating an anchor coat layer, performed where necessary, and forming a gas barrier coat layer.
