BIAXIALLY ORIENTED POLYAMIDE-BASED RESIN FILM

The invention provides a biaxially oriented polyamide-based resin film containing a polyamide-based resin together with a polyolefin-based elastomer and/or a polyamide-based elastomer. The film has the characteristics that (1) the number of Gelbo pinhole defects is not more than 5 when a twist and b...

Beschreibung
Zusammenfassung:	The invention provides a biaxially oriented polyamide-based resin film containing a polyamide-based resin together with a polyolefin-based elastomer and/or a polyamide-based elastomer. The film has the characteristics that (1) the number of Gelbo pinhole defects is not more than 5 when a twist and bend testing is carried out at 1° C. 1000 times using a Gelbo Flex tester; (2) the impact strength is not less than 0.9 J; (3) the total transmission haze value is not more than 5.0%; (4) the coefficient of static friction at a temperature of 23° C. and a relative humidity of 50% is not more than 0.7; and (5) the laminate strength of the laminated film obtained by laminating the biaxially oriented polyamide-based resin film and an unstretched polyethylene-based resin film is not less than 5.0 N/15 mm.
