Gas barrier biaxially stretched polyamide resin film and a production method thereof

Gas barrier biaxially stretched polyamide resin film and a manufacturing method thereof. Film, the double at least one side gas barrier coat layer of biaxially stretched polyamide resin film is formed, a thickness of the gas barrier coat layer is 0.5 to 5 [mu] m, the amount of the extracted monomer of the polyamide resin film is 0.1 wt% or less it is. Manufacturing method, the monomer removal step of the unstretched polyamide resin film, biaxial stretching process, the lamination step of laminating process and the gas barrier coat layer of the anchor coat layer which is performed as needed, including in this order.
