    摘要: A process for applying a barrier layer of ethylene/vinyl alcohol copolymer (EVOH) to a substrate, such as a plastic film, by coating the substrate with a solution of EVOH in a solvent of tetrahydrofuran and water, followed by removing the solvent. Multilayer structures having an EVOH barrier layer coated on a plastic substrate from solution in aqueous tetrahydrofuran solvent have excellent oxygen barrier properties.
