摘要:
At an optional stage in the production step of a biaxially stretched film using a polyamide resin including, as a first component, nylon 6, and as a second component, a polyamide including xylylenediamine and an aliphatic dicarboxylic acid having 4 to 12 carbon atoms, the film is brought into contact with water set at 40° C. or higher and lower than 70° C. for 1 to 10 minutes and further with water set at 70° C. or higher for 1 to 10 minutes. In the film thus obtained, the content of low molecular weight compounds is 0% by mass to 0.2% by mass.

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.
