The present invention aims to provide a biaxially oriented polyamide-based resin film which is excellent in laminate strength, pinhole resistance in low temperature, impact resistance, transparency, and keep good appearance even after being subjected to a hot water sterilization treatment. The present invention is a biaxially oriented polyamide-based resin film comprising a polyamide-based resin together with a polyolefin-based elastomer and/or a polyamide-based elastomer and satisfying the following conditions (1) to (5):
(1) that the number of Gelbo pinhole defects is not more than 5 when a twist and bend testing is carried out at 1°C 1000 times using a Gelbo Flex tester;
(2) that the impact strength is not less than 0.9 J;
(3) that the total transmission haze value is not more than 5.0%;
(4) that the coefficient of static friction at a temperature of 23°C and a relative humidity of 50% is not more than 0.7; and
(5) that the laminate strength of the laminated film obtained by laminating the biaxially oriented polyamide-based resin film and an unstretched polyethylene-based resin film is not less than 5.0 N/15 mm. |
