Abstract
An ostomy appliance is a convex product where a layer of adhesive is present to the convex side of the product. The adhesive is present on a thermoplastic carrier sheet disposed between the adhesive and a ring-shaped body having a convex proximal side, and the carrier sheet is attached, e.g. by welding, to the ring-shaped body along the inner periphery and the outer periphery thereof. At its peripheral, plane part, the appliance has a plane layer of a thermostable material, such as paper, in close connection with the adhesive. The thermostable material extends radially outside the outer periphery of the ring-shaped body and provides stability during thermoforming.
