evoh
– Ethylene-Vinyl Alcohol copolymer, used in coextruded plastic films to improve oxygen barrier properties. It is, however, a poor water vapor barrier. Even its otherwise excellent OTR, (oxygen transm [..]

pvdc
– Polyvinylidene chloride. A very good oxygen and water vapor barrier, but not extrudable, therefore it mostly used as a coating to improve barrier properties of other plastic films, (such as OPP and [..]
