BIAXIALLY ORIENTED POLYAMIDE RESIN FILM AND PRODUCTION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a biaxially oriented polyamide resin film combining transparency especially in a high-humidity atmosphere and slip properties and to provide a process for producing the same. SOLUTION: The film is produced from a polyamide resin containing 0.03-0.80wt.% fine particles for forming surface projections. In the film surface, the density of projections each having a height of 0.27μm or larger is at last 200 per mm<2> , and the areal content of microvoids is 0.1% or lower.
