<p>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, optionally positioning wound release material in the area(s) of the sheet or strip intended for wound contact, 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 general use as a disposable dressing. When the optional wound release material is eliminated, the bandage has special utility as an occlusive dressing. As a further option, the bandage may have a moisture vapor permeable, moisture impermeable skin thereon, to provide a water- and bacteria-proof protective outer layer for the foam bandage. </p> |
