Abstract: A disposable diaper comprising, an absorbent pad assembly, and a tape fastener comprising an elongated pressure-sensitive tape strip having a first section attached to a surface of the pad assembly and a second securement section extending from the first section in a longitudinal direction of the tape strip for securing the diaper about an infant. The tape strip has a backing of a non-reinforced, extensible polymeric film, with the film having an ultimate elongation of greater than 50% in the longitudinal direction of the tape strip, and having modulus properties such that the film has an elongation of 50% at 5-10 lbs./in. width of force as applied to the second section of the tape strip in the longitudinal direction thereof.

Abstract: A diaper fastener comprising an elongated strip of tape having an adhesive coated surface and a web adhesively secured to that surface in the longitudinally central portion of the strip, the exposed surface of the web having a limited affinity for the adhesive. The adhesive coated surface in one end portion of the strip is in contact with that exposed web surface. An opening is provided through the web whereby regions of adhesive in the end and center portions of the strip of tape which are aligned with the opening in the web are in contact with each other for releasably securing the end portion.
