Abstract

The invention relates to a gas-proof material which contains polyolefin, polyvinyl alcohol and polyamide. Said material is produced by mixing 3-60% by weight polyolefin, in which 0.01-10% by weight carboxylic acid has been copolymerized or grafted, 10-96% by weight internally softened vinyl alcohol polymer and 1-50% by weight polyamide in a molten state.
