ABSTRACT:
Adhesive bandages comprising a blister pad and adjacent adhesive-coated areas are prepared from heat-fusible bandage materials, preferably a nonwoven batt material, by applying the pad material to a base material and heat-welding around the perimeter of the pad to totally enclose the interior thereof. The portions of the base material extending from the pad area are compacted under heat and pressure to provide a surface suitable for a coating with adhesive. A medicated gel or other therapeutic material may be included within the confines of the pad area to provide a medicated blister bandage.
