Abstract

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.
