Abstract:
1. A process for making an embossed film web, comprising: feeding a precursor film web between a static gas pressure plenum and a forming structure comprising a plurality of discrete apertures, discrete depressions, or combinations thereof, the apertures or depressions having a depth of at least substantially equal to a thickness of the precursor web, wherein the static gas pressure plenum creates static pressure conditions; applying a vacuum on a forming structure facing surface of the precursor film web; and applying static pressure from the static gas pressure plenum against the precursor web opposite the forming structure creating a pressure differential across the precursor web sufficient to force the precursor web into the apertures or depressions of the forming structure, thereby forming the embossed web comprising a plurality of discrete extended elements having open proximal ends, wherein no heat is added to the forming structure or the precursor film.
