PROBLEM TO BE SOLVED: To provide a biaxially stretched polyamide film having good easy adhesiveness and heat shrinkability, a lamination film excellent in lamination strength and suppressed in delamination and lower expansion deformation due to boiling treatment, and a packaging bag. SOLUTION: The heat-shrinkable polyamide film has an easily adhesive film on at least the single surface thereof. The hot water shrinkage factor in the MD and TD directions of the heat-shrinakable polyamide film, after the film is allowed to stand for 24h under an environment of a temperature of 20 deg.C and a relative humidity RH of 65% and subsequently immersed in hot water at 100 deg.C for 30 min, is 23-26% and the hot water shrink stress in the MD and TD directions of the film is 46-85 mN/cm per a thickness of 1μm. |
