1. A cross directionally elastically extensible nonwoven laminate comprising:

  • an elastic film layer autogenously bonded along at least one face to an asymmetric nonwoven web along a plurality of cross direction extending bond lines where the asymmetric nonwoven fibers are at least partially embedded into the elastic film along the bond lines, the elastic film layer is morphologically substantially the same at the bond lines as between the bond lines and the elastic film layer remains substantially elastic at the bond lines and wherein the asymmetric nonwoven web ratio of machine direction tensile strength to cross direction tensile strength is at least 4.
