  • Patent number: 4901714
    Abstract: A layer of plastic, either in film or coating form, is bonded to a sheet of non-woven material to form a base. When film is used, it is preferably smaller in size than the non-woven material and affixed to the top surface thereof by an acrylic adhesive. The plastic film is coated, on its exposed surface, with a layer of acrylic adhesive. When the plastic is in the form of a coating, it is bonded to the bottom surface of the non-woven material. A superabsorbent pad, smaller in size than the base, is wrapped in non-woven material and affixed to the base by the exposed adhesive layer. The remaining portion of the exposed adhesive layer forms a border around the superabsorbent pad for adhering the bandage to the skin.
