Abstract
A disposable absorbent article comprises an absorbent panel and a backing web secured to the panel. A preferred form of the web comprises an apertured film. The web may also include other components on the apertured film, including adhesive. The apertured film is preferably produced from a solid precursor film. The precursor film comprises a copolymer of ethylene and a comonomer polymerized using a single-site metallocene-type polymerization catalyst. The apertured film is formed from the precursor film so that the apertured film has localized deformations and apertures therein. The apertured film exhibits breathability, strength, and flexibility with an elasticity accommodating stretch or elongation and at least partial recovery.
