Abstract
A stretch laminate having a first nonwoven material, a second nonwoven material, an elastic film. The elastic film may be interposed between said first and second nonwoven material. The elastic film has a first longitudinal side edge and a second longitudinal side edge. The stretch laminate further has a first plane of adhesive having differing amounts of adhesive as measured laterally within the stretch laminate. The differing amounts of adhesive being controllable. The first plane of adhesive being interposed between the first nonwoven material and the elastic film. The stretch laminate further has a second plane of adhesive having differing amounts of adhesive as measured laterally within the stretch laminate. The differing amounts of adhesive being controllable. The second plane of adhesive being interposed between the second nonwoven material and the elastic film. Each of the above elements are substantially laminated together to form a laminate. The laminate is activated to form the stretch laminate.
