Abstract

The present invetnion relates to a composite structure comprising a hydrocolloid and a hyrogel. In one embodiment, the composite structure comprises an island dressing comprising one layer of a hydrogel and another layer of a hydrocolloid. In yet another embodiment, the hydrocolloid is composed of a meterial that has a swell ratio of about 1% to about 35% (measured by ASTM D 2765-95). In a further embodiment, the composite structure comprosies three layers: (a) a hydrogel; (b) a liner composed of a low moisture vapor transmission rate plastic or composition; and (c) a hydrocolloid having a low swell ratio. In another embodiemnt, the present invention comprises a method of making the composite structure of the present invention.
