A refastenable diaper is provided with a securing zone on the diaper outer cover of a peak strength of less than 2750 grams/inch. A refastenable adhesive taping system for the diaper includes an adhesive fastening tape comprising a flexible backing and a layer of pressure-sensitive adhesive permanently combined to said flexible backing and adapted to be applied to and released from the securing zone to fasten and open the diaper. The adhesive exhibits a 180.degree. peel adhesion of the tape to the securing zone that is less than the peak strength of the securing zone. The adhesive is selected to be within a specified rheological window, that is, have a maximum tan delta, or (tan delta).sub.max, of from 1.5 to 2.5 at 20.degree. C., reached at a frequency, or (w).sub.max, of greater than 500 rad/sec.

Refastenable adhesive taping system

An article includes a distinctive refastenable adhesive taping system. The article comprises an outer cover which has waistband sections positioned at opposite ends thereof and has an intermediate section which interconnects the waistband sections. The outer cover includes a securing zone which is located at a first of the waistband sections and which provides a landing surface appointed for receiving adhesion of one or more adhesive tabs thereon. The securing zone has a selected peak tensile strength and a selected rigidity value. An adhesive tab is located at at least one lateral side edge of a second of the waistband sections for securing the waistband sections around a wearer. The tab includes a backing layer and an adhesive layer, and, when adhered to the landing surface, has a 180.degree. peel adhesion value which is less than the peak strength of the securing zone. The backing layer has a rigidity value selected to provide a rigidity ratio of not more than about 10:1, where the rigidity ratio is determined by dividing the backing layer rigidity value by the securing zone rigidity value. The securing zone and adhesive tab thereby provide an improved refastenable taping system.
