  • Patent number: 5824352
    Abstract: An apparatus for producing an apertured plastic film having a tricot-like texture. The apparatus includes a film forming member comprising a rotatable hollow drum having a pattern of apertures and a topographical outer surface formed by a cluster of peaks and valleys surrounding each aperture. A plastic film is placed on the apices of the peaks and fluid streams are projected against the film while the drum is rotated. The fluid forces the film against the topographical outer surface of the drum causing the film to become apertured and to have a tricot-like texture corresponding to the pattern of apertures and peaks and valleys.

  • Patent number: 5681301
    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.
