Abstract
An ostomy appliance includes a multilayer composite film comprising at least one foam layer. An outer foam layer can function as a skin contact layer providing comfort and softness characteristics that are comparable to a nonwoven comfort layer. Preferably, at least one foam layer includes a vinyl-bond rich triblock copolymer and provides sound absorbing properties. The multilayer composite film can also include at least one layer comprising a filler to further enhance sound absorbing properties.
