Various polymeric barrier compositions are described which when formed into films, are useful in reducing transmission of odors. The films can be incorporated into a wide range of products such as multilayer barrier films used in medical applications and particularly in ostomy appliances. In certain versions, the films include blends of amorphous cyclic olefin copolymers and semi-crystalline cyclic olefin copolymers.
