ABSTRACT:
Improved adhesive tabs for fastening disposable garments, e.g., diapers, about the body of a wearer by adhering the tab to an outer portion of the garment made of plastic film of predetermined tensile strength carry a pressure-sensitive adhesive coating having an adhesive strength when plotted as the ordinate against speed of removal from a reference substrate as the abscissa that asymptotically approaches, but does not exceed, the value of the film's predetermined tensile strength whereby the adhesive tab may be repeatedly adhered to and removed from the garment outer portion to fasten and unfasten the garment without tearing its outer portion film. The required adhesive strength property of the adhesive tabs is attached by constructing them to include a backing web, preferably a laminated, multi-layer web, and a first layer of pressure-sensitive adhesive covering one surface of the web, adhering a sheet of non-woven fabric to such first layer on the side thereof opposite to the web and having a second layer of the pressure-sensitive adhesive covering the surface of such sheet opposite to the web so the second layer presents an adhesive surface opposite to the non-woven sheet by which the tab may be adhered to the garment outer portion film.
