A disposable bandage, and a process for manufacturing it, which is prepared from a single sheet or strip of liquid permeable, flexible thermoplastic hydrophilic foam. The process includes coating the entire surface of one side of a foam sheet or strip with a layer of porous pressure sensitive adhesive, covering the same side of the laminate with a suitable release liner and heat compressing the laminate except in the area of the laminate intended for wound contact. The foam bandage so produced includes both a resilient absorbent pad and thin but absorbent adhesive-coated tabs and is suitable for use as an occlusive dressing. Optionally, the bandage may have a moisture vapor permeable, moisture impermeable skin thereon, to provide a water- andbacteria-proof protective outer layer for the foam bandage. |
