Abstract
An ostomy appliance wafer has a skin facing layer of adhesive applied to a proximal side of a film layer to define a proximal skin facing surface of the ostomy appliance wafer, and the skin facing layer of adhesive has a thickness in a range between 25 to 200 micrometers.
Claims16
An ostomy appliance wafer comprising:
- a backing layer having a distal side that defines a distal wafer surface of the ostomy appliance wafer, where the distal wafer surface is configured to receive a waste collection pouch;
- a first layer of adhesive applied to a proximal side of the backing layer;
- a film layer applied to the first layer of adhesive;
- and
- a skin facing layer of adhesive applied to a proximal side of the film layer and defining a proximal skin facing surface of the ostomy appliance wafer;
- wherein the skin facing layer of adhesive has a thickness in a range between 25 to 200 micrometers;
- wherein the skin facing layer of adhesive has a moisture permeability above 100 g/m2/24 h.
