Abstract:

Essentially amorphous non-chlorinated polymeric films are provided which are effective barriers to odors and organic molecules, making them particularly useful for ostomy bags (colostomy, ileostomy), trans-dermal delivery systems (TDDS), cosmetic patches, incontinence bags, medical collection bags, parenteral solution bags, and food packaging, as well as for protective clothing and soil fumigation applications. The barrier layers of the present invention can be used as monolayers or can be a component film of a multilayer structure. The barrier films may be used with or without other film layers that promote reduced noise emission. Alternately, single and multi-layer films may omit the barrier layer in favor of the reduced noise emission layers.
