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 semi-crystalline cyclic olefin copolymers.

The process to fabricate a polymer film includes baking a cyclic olefin copolymer (COC) and a silicon wafer at a predefined temperature. The process also includes attaching a plastic tape frame to the silicon wafer and submerging the COC and the plastic tape frame within water allowing one or more ultra-thin sheets of COC film to be peeled off.
