1. An absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between the topsheet and the backsheet, wherein the topsheet comprises a laminate web comprising a first layer comprising an extruded polymer film and a second layer comprising a nonwoven web, wherein the polymer film and the nonwoven web have been joined to form a precursor laminate while the film was in a softened state thereby to bond to the nonwoven, the precursor laminate having a first side defined by the polymer film, and an opposing second side defined by the nonwoven;
wherein the first layer has a pattern of relatively smaller apertures formed therethrough, wherein the apertures have a diameter of less than about 500 microns, and wherein the first layer comprises at least about 95 discrete apertures per square centimeter, wherein the laminate has a pattern of relatively larger protrusions formed therein, wherein each of the first layer and the second layer form the larger protrusions, wherein the relatively larger protrusions being of a size sufficient for a plurality of the relatively smaller apertures to be present within each of a plurality of the protrusions, wherein each large protrusion defines a void area interiorly, wherein each of the larger protrusions has a base, wherein the base and the first side are coplanar, wherein each of the larger protrusions comprises a plateau and a sidewall extending from the plateau to the base, wherein the base is wider than the plateau, and wherein the first layer is stretched to form the larger protrusions such that a portion of the first layer forming the larger protrusion has a reduced thickness as compared to the base and such that the apertures present within each of the plurality of protrusions are enlarged relative to the apertures present elsewhere on the first layer;
wherein the first layer is an outer most layer of the absorbent article facing the skin of a wearer;
wherein the pattern of relatively smaller apertures and the pattern of relatively larger protrusions extends throughout the liquid permeable topsheet;
wherein the nonwoven web comprises a carded nonwoven comprising bicomponent fibers.
