Abstract
A polyamide film having been drawn at a draw ratio of 2 or more in at least one direction, which comprises a polyamide resin composition comprising from 90 to 99.99% by weight of a polyamide and from 10 to 0.01% by weight of a fluoromica-based mineral with swelling characteristics. The film is excellent in piercing pinhole strength and mechanical strength and heat dimensional stability after a retort treatment.
