Layers of thin thermoplastic film are brought into contact with opposite surfaces of superposed layers of absorbent material, such as sheets of fibrous crepe paper of facial quality, rayon fibers, or flexible polyurethane foam. The layers of plastic film are covered with a loosely-woven cotton scrim or gauze (or with spun-bonded nylon). Additional layers of the thin plastic film may then cover the exterior surfaces of the scrim layers. The multi-layer article thus formed is then compressed and heated to melt the plastic films. The melted plastic bonds the scrim to the paper, separating as it melts to communicate the absorbent paper core with the exterior of the pad and to gather itself about the threads of the scrim in wrapping, covering engagement. The resultant pad is highly absorbent upon contact with a liquid, yet the absorbed liquid will not "bleed" back from the pad thus making it highly desirable as a surgical sponge or bandage.
