Abstract:
1. A method for creating a textured film, the method comprising: aperturing a polymeric film web having first and second planes by a solid or molten phase forming technique, the aperturing forming open conical perforations which extend outward beginning from the first web plane and which are spaced at a density of between 35-80 perforations per linear inch; and embossing the apertured web by contact with a patterned embossing roll facing the first web plane so as to flatten some of the perforations, spaced projections of the embossing roll leaving footprint impressions of at least 1/1000 of an inch in said web extending away from the second web plane, wherein each footprint impression provides a flattened first web plane land area comprising flattened conical perforations so as to leave unflattened conical perforations outside of each footprint.
