ABSTRACT:
A blend consisting essentially of a major portion of an amorphous polyamide and a minor portion of an ethylene vinyl alcohol copolymer exhibits gas barrier properties which are less dependent on humidity than are those of either of the component polymers. Films and laminated structures which incorporate the material of these blends are suitable for use as packaging materials.
