<p>A stretched polyamide film obtained by melt-kneading and extruding a mixed resin (Z) containing a polyamide resin (X) and a modified resin (Y) into a film followed by biaxial stretching, wherein the polyamide resin (X) is obtained from a diamine component containing not less than 70 mol% of a metaxylenediamine and from a dicarboxylic acid component containing not less than 70 mol% of an alpha , omega -aliphatic dicarboxylic acid having 6 to 12 carbon atoms; the modified resin (Y) is obtained by graft-modifying an ethylene-ethyl acrylate copolymer resin with a maleic anhydride; and the mixed resin (Z) contains from 80 to 99% by weight of the polyamide and from 20 to 1% by weight of the modified resin. The stretched film exhibits not only excellent transparency and gas-barring property but also excellent flexibility and shock resistance.</p> |
