Abstract
An absorptive device includes a topsheet, a backsheet, an absorbent core between the topsheet and the backsheet, and an acquisition distribution layer between the topsheet and the absorbent core. The acquisition distribution layer includes a formed film having a plurality of lands that contact a bottom surface of the topsheet and define an irregular array of cells.

An absorptive device comprising:
- a topsheet;
- a backsheet;
- an absorbent core between the topsheet and the backsheet;
- and
- an acquisition distribution layer between the topsheet and the absorbent core, the acquisition distribution layer comprising a formed film having a plurality of lands that contact a bottom surface of the topsheet and define a first irregular array of cells,
- wherein the first irregular array of cells is comprised of a random variety of shapes forming no regular geometric shapes,
- wherein the first irregular array of cells is configured to render the plurality of lands invisible to a naked eye when the absorptive device is viewed from above the topsheet, and
- wherein at least some of the first irregular array of cells have an inscribed circle diameter of between about 800 microns and about 1400 microns.

An acquisition distribution layer, comprising:
- a plurality of lands;
- and
- a plurality of cells surrounded by the plurality of lands,
- wherein the plurality of lands define an array of the plurality of cells, and
- wherein each of the plurality of cells in the array of the plurality of cells are irregularly shaped, such that the plurality of cells comprises a random variety of shapes forming no regular geometric shapes,
