Abstract

L'invention concerne diverses compositions polymères à fonction de barrière qui, lorsqu'elles sont mises sous forme de films, sont utiles pour réduire la transmission des odeurs. Les films peuvent être intégrés à une grande variété de produits tels que des films multicouches formant barrière employés dans des applications médicales et en particulier dans des dispositifs de stomie. Dans certaines versions, les films comprennent des copolymères cyclo-oléfines semi-cristallins.
