  • Patent number: 11154427
    Abstract: Medical tape suitable to be adhered onto a skin wound for healing of the skin wound or onto a scar for suppressing a thickening, an expansion and an extension of the scar after healing of the wound. The medical tape includes a flexible and stretchable substrate consisting of a plastic film or foil; a release paper which is adhered to one side of the substrate via a pressure-sensitive adhesive layer; and a peelable support consisting of two sheets of plastic films which are adhered to another side of the substrate via a silicone-coating layer and a slightly adhesive layer, in that order. The two sheets of plastic films are butted with each other at the midpoint of a longitudinal direction of the substrate, and over a widthwise direction of the substrate. The medical tape advantageously applies a shrinking force only to a wound surface or a scar surface.
