Abstract
A low profile heat-sealable adsorbent filter for ostomy appliances is provided. The filter comprises a heat-sealable microporous film layer, a filter layer of melt-blown microfibers loaded with adsorbent particles and a cover layer. The microporous film layer provides for rapid release of flatus or other gas in having a Gurley value of less than about 100 seconds/50 cc. The melt-blown microfiber filter web has an estimated service life of about 3 days or more with a web basis weight of about 700 grams/m.sup.2 or less. The low profile filter can be sealed to the outside face of an ostomy appliance with a perimeter seal to provide a filter with no liquid or gas by-pass and no liquid by-pass through the filter.
