Abstract (en)
[origin: WO2013028398A1] 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.
