Abstract
The hydrocolloid disk includes a polyethylene/PVDC film backing. The disk adheres to the acrylic adhesive layer of the collar over a large portion of the surface area of the disk. The collar is formed of a EVA/polyethylene perforated film on a polyethylene non-woven. In the one piece embodiment, the collar is secured directly to the pouch. In the two piece embodiment, the collar is secured directly to the coupling ring. Increased strength, better odor protection and improved breathability are achieved.
