BACKGROUND [0001] 1. Technical Field [0002] The present disclosure generally relates to absorbent articles, and more particularly to an absorbent article having an elastic laminate structure, that is smooth, low cost and easily manufactured, for improving fit, aesthetics and leakage resistance. [0003] 2. Background of the Related Art [0004] Absorbent articles such as, for example, disposable diapers, adult incontinent pads, sanitary napkins, pantiliners, incontinent garments and the like are generally worn, in cooperation with garments and disposed against a body surface by infants or adult incontinent individuals. The absorbent article is employed to collect and absorb body fluid discharge, such as, for example, blood, menses, urine, aqueous body fluids, mucus, cellular debris and other forms of body discharge. For example, the absorbent article may be disposed between the legs of an individual adjacent a crotch area. The absorbent article is positioned with a garment and drawn into engagement with a body surface of the crotch area to collect body discharge. [0005] As is known, absorbent articles typically include a fluid permeable coverstock for engaging the body surface, a fluid impermeable backsheet and an absorbent core supported therebetween. The backsheet serves as a moisture barrier to prevent fluid leakage to the garment. The absorbent core usually includes a liquid retention material that faces the body surface. The absorbent core can include, for example, loosely formed cellulosic fibers, such as, for example, wood pulp, rayon, or cotton for acquiring and storing body discharge. The absorbent core may also include tissue wrapping or wadding, and or super absorbent polymer. [0006] Some absorbent article designs typically incorporate elastic elements in the waist, stomach, and leg areas for improving the fit, aesthetics and leakage resistance. The waist and stomach elastic elements increase the flexibility of the absorbent article, allowing the same article to accommodate a greater range of body sizes. In addition, they make the article more form-fitting for the wearer. Leg gather elastic elements and standing leg gathers have also been employed to help reduce leakage from the article when the absorbent cores cannot absorb body exudates fast enough. [0007] Typically, these elastic elements include elastic strands to provide the absorbent article with retractive forces and a desired range of extension. Attachment of the elastic strands to the absorbent article can, however, create undesirable corrugations in the surface of the absorbent article. These disadvantageous corrugations may have a high amplitude and low frequency such that protuberances are formed giving the absorbent article a "bumpy" feel. [0008] In an attempt to overcome these disadvantages, elastic films have been employed. Elastic films, however, may suffer from various drawbacks such as high cost, lower retractive forces and lower range of extension. [0009] It would therefore be desirable to overcome the disadvantages and drawbacks of the prior art by providing an absorbent article, including an elastic laminate having an elastic film and elastic strands. Such an elastic laminate is configured to provide higher retractive forces and a wider range of extension. Desirably the elastic laminate is joined with the absorbent article to provide a substantially smooth surface laminate and comfort. It is contemplated that the elastic laminate is low cost and facilitates easy and efficient manufacture of the absorbent article. SUMMARY [0010] Accordingly, an absorbent article, including an elastic laminate having an elastic film and elastic strands is disclosed. The elastic laminate is configured to provide higher retractive forces and a wider range of extension, and is joined with the absorbent article to provide a substantially smooth surface laminate and comfort. The elastic laminate is low cost and facilities easy and efficient manufacture of the absorbent article. Objects and advantages of the present disclosure are set forth in part herein and in part will be obvious therefrom, or may be learned by practice of the present disclosure that is realized and attained by the instrumentalities and combinations pointed out in the appended claims for the devices and methods of the present disclosure consisting of its constituent parts, constructions, arrangements, combinations, steps and improvements herein shown and described. [0011] In one particular embodiment, an elasticized panel laminate includes a first nonwoven layer and a second nonwoven layer. An elastomeric film is positioned between the first and second nonwoven layers. The panel further includes a plurality of elastic strands positioned between the first and the second nonwoven layers. The elastic film layer- may include a plurality of spaced apart film strips. The elastic strands can be positioned directly on the film strips, or in the spaces adjacent the strips. [0012] In an alternative embodiment, the elasticized panel laminate may include a plurality of elastic film layers. A first elastic film layer is positioned adjacent the first nonwoven layer, and a second elastic film layer is positioned adjacent the second nonwoven layer. The layer of elastic strands is positioned between the first and the second elastic film layers. [0013] In another alternative embodiment, the elasticized panel laminate may include a plurality of elastic strand layers. A first elastic strand layer is adjacent the first nonwoven layer. A second elastic strand layer is positioned adjacent the second nonwoven layer. The elastic film layer is positioned between the first and the second elastic strand layers.
