Abstract
A perforated laminate comprising at least first and second layers and apertures extending through at least the first layer. The first layer is a nonwoven or formed film material, and the second layer comprises an absorbent structure. The at least first and second layers are primarily joined at the periphery of the perforated apertures. The laminate is particularly useful as a topsheet for an absorbent article, such as a disposable diaper or sanitary napkin. Also described are various materials and methods used to create such laminates.
