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.
