PROBLEM TO BE SOLVED: To provide a gas barrier laminated film suitably usable for heat sealing without impairing excellent gas barrier properties even after boiling by providing excellent strength characteristics and the gas barrier properties. SOLUTION: In the gas barrier laminated film comprising a gas barrier layer made of an inorganic deposited layer and formed on one or both side surface sides of a base layer formed of a polyamide film and a heat sealing layer, shrink stresses of all directions at 170 deg.C of the polyamide film for constituting the base layer are all 950gf/mm<2> or less, and shrinkage factors of all the directions when it is heat treated at 170 deg.C for 10min are all 4.0% or less. Thus, the laminated film or sheet exhibiting excellent gas barrier properties even after boiling can be obtained. |
