Biaxially stretched polyamide resin film

摘要

Disclosed is a polyamide resin film which has excellent dimensional stability with respect to moisture absorption, excellent mechanical characteristics and sliding properties under high temperature and high humidity conditions, and excellent handling properties. Specifically disclosed is a biaxially stretched multilayer polyamide resin film having 8 or more layers in total and using a same resin composition for 80% based on the ratio of the number of the layers, wherein the film is stretched 2.5 to 5.0 times in the longitudinal direction of the film and has an in-plane orientation coefficient (Delta P) of 0.057 to 0.07 and a strain of 0.1 to 2.0% after boiling treatment.
