摘要：
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.
