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, positioning wound release material in the area 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 at the locus of the wound release material. The foam bandage so produced includes both a resilient absorbent pad and thin but absorbent adhesive-coated tabs. Optionally, 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.
A foam bandage, comprising a laminate having a liquid permeable foam layer and a liquid permeable porous pressure sensitive adhesive layer, and having a wound release material adjacent said adhesive for separating said adhesive from a tissue healing area, and securement means associated with said laminate to attach the laminate.
