Manufacturing a thermoplastic composition, there is first melt-blended a polymer (A)containing polyether chains, e.g. a polyetherpolyamide block copolymer, with (C) a vinyl compound, e.g. a copolymer of styrene and maleic anhydride and/or a compatibilizing agent (D), e.g. a graft copolymer with a polyolefin with an unsaturated carboxylic acid and the resultant melt-blended mixture is pelletized. The resultant pellets are then blended with a polyolefin (B) e.g. polyethylene. The resultant overall blended mixture can then be molded into films having a low variation in thickness of a desired permeability of water vapor and other gases.
