An apertured extrusion coated nonwoven web for use as a topsheet in an absorbent article includes a nonwoven material having a user-facing side and a garment-facing side opposite the user-facing side. The nonwoven material includes a plurality of fibers. The apertured extrusion coated nonwoven web also includes a polymer coating on the garment-facing side of the nonwoven material, the polymer coating having a basis weight of about 2 gsm to about 6 gsm, and a plurality of three-dimensional apertures that extend through the nonwoven material and the polymer coating. Each of the plurality of three-dimensional apertures includes a continuous sidewall extending from a garment-facing side of the polymer coating. The apertured extrusion coated nonwoven web has an open area of greater than 5% when subjected to a pressure of 0.6 psi.

A polymeric film is provided, the film comprising one or more land portions that are substantially coplanar in a base plane and a plurality of distended portions separated from one another by the one or more land portions. The distended portions bow distally outward from the base plane. The polymeric film further comprises a plurality of annular micro-protrusions extending outward from the distal film surface, each protrusion having an apex. A portion of the plurality of annular micro-protrusions extends from each of the one or more land portions of the polymeric film and from each of the distended portions of the polymeric film.

A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.

A method of manufacturing an activated composite web includes laminating a film layer to a nonwoven web to form a composite web, forming a plurality of apertured protuberances in the film layer, and passing the composite web through intermeshing elements to form an activated composite web. The intermeshing elements form a plurality of first lanes, with first widths, substantially unaffected by activation, and a plurality of second lanes, with second widths. The second widths are less than the first widths. Portions of the plurality of apertured protuberances define first apertures in the first lanes and second apertures in the second lanes. The cross-sections of the second apertures are larger than the first apertures. The first apertures have their major axes substantially aligned in the first direction while the second apertures have their major axis substantially aligned in the second direction. An activated composite web also is provided.

A formed film includes a first surface generally located in a first plane, a second surface generally located in a second plane parallel to and spaced from the first plane, and a third surface generally located in a third plane parallel to and spaced from the first plane and the second plane, in between the first plane and the second plane. A porous structure extends between the second surface and the third surface. A plurality of raised areas have sidewalls that extend between the first surface and the third surface, and top portions that define the first surface. The plurality of sidewalls, the porous structure, and the first plane define a plurality of gathering volumes.

Formed films and apparatus for manufacturing the same

An activated composite web includes a nonwoven layer, and a formed film layer attached to the nonwoven layer. The formed film layer includes a plurality of first apertured protuberances having a mesh count of at least 35, and a plurality of second apertured protuberances. Each of the second apertured protuberances has a cross-sectional area larger than each of the first apertured protuberances. A plurality of first lanes are aligned in a first direction and have a first width extending in a second direction substantially perpendicular to the first direction. The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.
