Provided is a biaxially oriented polyamide-based resin film which exhibits excellent laminate strength, low-temperature pinhole resistance, impact resistance, and transparency, and which maintains an excellent external appearance even if subjected to sterilization treatment in hot water. This biaxially oriented polyamide-based resin film includes a polyamide-based resin, and a polyolefin-based elastomer and/or a polyamide-based elastomer, and satisfies conditions (1)-(5): (1) that the Gelbo pinhole defect number when a twist-flex test using a Gelbo flex tester has been performed 1000 times at a temperature of 1˚C be not more than 5; (2) that the impact strength be at least 0.9 J; (3) that the total transmission haze value be not more than 5.0%; (4) that the static friction coefficient at a temperature of 23˚C and a relative humidity of 50% be not more than 0.7; and (5) that the laminate strength of a stacked film obtained by laminating the biaxially oriented polyamide-based resin film and an unstretched polyethylene-based resin film be at least 5.0 N/15mm. |
