To provide a method for producing a polyamide resin film by using a polyamide resin obtained through polymerization of a regenerated monomer used as a recycled material. Provided is a method for producing a polyamide resin film, including: (1) a step of producing a monomer from a raw material (A) for depolymerization, (2) a step of producing a polyamide resin (B) through polymerization using a raw material containing the monomer. (3) a step of refining the polyamide resin (B), and (4) a step of producing an unstretched film using a starting material containing the refined polyamide resin (B), and stretching the unstretched film.
A method for producing a polyamide resin film, the method comprising:
A polyamide resin film, wherein, when the film is halftone-printed, the polyamide resin film includes 100 or fewer missing dots in 1000 mm2 of a 10% gradation part in a halftone-printed film.
