1. A method of forming a side panel for an absorbent article; the method comprising steps of:
providing a first substrate and a second substrate, each defining a width in a cross direction;
creating a morphological difference in a first region of the first substrate but not in a second region of the first substrate to form a modified substrate;
providing an elastomeric material comprising a first edge region and a second edge region separated from the first edge region in the cross direction by a central region;
stretching the central region of the elastomeric material in the cross direction;
positioning the stretched central region of elastomeric material between the modified substrate and second substrate; and
forming an elastic laminate by ultrasonically bonding the modified substrate together with the stretched central region and the second substrate; wherein the first region of the modified substrate is in at least partial overlapping relationship with an unstretched region of the elastic laminate and wherein the second region of the modified substrate is in at least partial overlapping relationship with the stretched central region of the elastomeric material.
