BIAXIALLY-ORIENTED NYLON FILM, LAMINATE FILM, LAMINATE PACKAGING MATERIAL, BATTERY, AND METHOD FOR PRODUCING BIAXIALLY-ORIENTED NYLON FILM

摘要

The biaxially-oriented nylon film (3) of the present invention is a biaxially-oriented nylon film (3) having nylon resin as a starting material, wherein the average tensile shock elasticity in four directions as stipulated by JIS K7160 is at least 4800KJ/m². The ratio of the maximum to minimum tensile shock elasticity (maximum/minimum) does not exceed 1.30.
