ABSTRACT:
Blends of a major portion of ethylene vinyl alcohol copolymer (EVOH) and a minor portion of an amorphous polyamide and preferably also a semicrystalline nylon are disclosed. These blends may be formed into films or multilayer structures, which can be thermoformed into containers or other articles. The presence of the minor portion of amorphous polyamide permits thermoforming of the EVOH at lower temperatures without the formation of defects.
