摘要： An integral absorbent article has a longitudinal article length and a lateral article width. The article includes an absorbent composite having first and second longitudinally opposed end regions, laterally opposed side regions, a bodyside surface, an outward surface, and a first longitudinally terminal end edge. The absorbent composite further includes a substantially liquid-impermeable backsheet layer; a liquid permeable topsheet layer; and a retention portion sandwiched between said backsheet and topsheet layers. An extensible outercover is joined to extend over a major portion of said outward surface of the said absorbent composite. The extensible outercover is desirably capable of providing a the selected elongation when subjected to a tensile force. The extensible outercover is also desirably capable of providing a selected, sustained deformation, when subjected to an applied tensile force and then allowed to relax after a removal of the applied force. In particular aspects, the outercover can provide an elongation of at least about 1 cm when subjected to a tensile force of 30 gmf per inch. In further aspects, the extensible outercover may also provide a substantially permanent deformation of at least about 20%, when subjected to a tensile force of 50 gmf per inch and then allowed to relax for a period of 1 minute (after a removal of the applied tensile force).
