摘要： PROBLEM TO BE SOLVED: To prevent gas barrier properties from being impaired through a boiling treatment or a printing process by a constitution wherein a gas barrier layer made of a thin film metal oxide layer is formed on a layer A formed on one side of a polyamide film consisting of layers A/B under the constitution that a polyolefin film is laminated onto the gas barrier layer. SOLUTION: On a layer A of a polyamide film prepared by laminating a resin composition used in a layer A and a resin composition used in a layer B, a gas barrier layer made of a thin film metal oxide layers is formed so as to laminate a polyolefin film to the gas barrier layer. At this time, a polyamide resin composition used in the layer A is prepared by compounding 50-0 pts.wt. of an aliphatic polyamide-based resin and 0-10 pts.wt. of a flexing fatigue resistance improver with 50-100 pts.wt. of a terephthalic acid-containing resin. In addition, a polyamide resin composition used in the layer B mainly consists of the aliphatic polyamide resin.
