PROBLEM TO BE SOLVED: To provide a polyamide laminated biaxial stretched film which is effective for preventing dropping destruction of a large heavy bag for business use or the like, and is suited to various packages. SOLUTION: The polyamide laminated biaxial stretched film is prepared by stacking a layer A containing a mixed polyamide polymer consisting of 97 to 85 wt.% of an aliphatic polyamide polymer and 3 to 10 wt.% of a metaxylene-based polyamide polymer, or prepared by adding 0 to 5.0 wt.% of thermoplastic elastomer on at least one surface of a layer A consisting of a mixed polymer of 99.5 to 70 wt.% of an aliphatic polyamide polymer, 0.5 to 10 wt.% of thermoplastic elastomer, and/or 3 to 20 wt.% of an aliphatic copolymber polyamide polymer. Wherein, impact strength is≥0.7 J, sticking strength is≥10 N, a static friction coefficient at 23°C, 65 %RH is≤0.90, the number of bent pinhole defects at a low temperature is≤5 pieces, and laminate strength is≥5.0N.
