Abstract
The present invention provides a multilayered polyamide film having at least two polyamide resin layers, which develops less than 10 pinholes when evaluated for pinhole resistance by flexing it 1,000-times at 25° C. and which has an elongation of 6 mm or less at 120° C. in vertical pitch evaluation. This film has excellent resistance to pinholes and is well suited for lamination.
Claims11
A multilayered polyamide film comprising at least two polyamide resin layers, the film having excellent processability such that the film develops less than 10 pinholes when evaluated for pinhole resistance by being flexed 1000 times at 25° C., and has an elongation of 6 mm or less at 120° C. in vertical pitch evaluation, wherein at least one of said polyamide resin layers comprises 97 to 93 weight % of polyamide and 3 to 7 weight % of a modified ethylene-vinyl acetate copolymer.
