Abstract
A method of making extensible web laminates comprising a multilayer film and at least one web layer and the use of such extensible web laminates in personal care articles. The method generally includes activating the multilayer film in a first direction by stretching at least a portion of the multilayer film past the elastic deformation limit of the skin layers and recovering the skin layers with the elastomeric core layer to produce a multilayer film that is elastic in the first direction. The activated multilayer film is subsequently stretched beyond the deformation limit of the skin layers in a second direction substantially perpendicular to the first direction. At least one web layer is applied to the multilayer film while in the stretched state. The multilayer film is then recovered to produce an extensible web laminate.
