An efficient, in-line method for forming an elastic laminate is provided. To form the laminate, a polymer composition containing an elastomeric polymer is extruded as a film. In one embodiment, the film is uniaxially oriented in the machine direction (“MD”), or optionally, biaxially oriented in the machine direction and the cross-machine direction (“CD”). Regardless, the elastic film is then laminated to a nonwoven web material. Prior to lamination, the percent stretch of the nonwoven web material is generally no more than 25% when 500 grams-force is applied per 3 inches of the material in either the cross-machine or machine direction. Such a relatively inextensible nonwoven web material may restrict the overall extensibility of the laminate. Thus, to improve extensibility, the resulting laminate is mechanically stretched in the cross-machine and / or machine directions. Extensibility may also be improved by allowing the laminate to relax and retract prior to winding so that the nonwoven web material gathers or forms buckles.
