An elastic composite formed from a lightweight nonwoven facing that has a low degree of strength in the cross-machine direction ('CD') is provided. Through selective control over certain parameters of the materials employed in the composite and the formation process, the present inventors have discovered that such low strength and lightweight facings may be readily laminated to an elastic film without significantly damaging their integrity. For example, in one embodiment, the elastic film may possess a multi-layered construction that includes an elastomeric elastic layer positioned adjacent to a strength-enhancing thermoplastic layer. The polymer content and thickness of the thermoplastic layer are generally selected to impart additional strength and integrity to the film. Likewise, the polymer content of the elastic layer may also be selected so that the film possesses a sufficient tack for adhering to the facing. In certain cases, it may be desirable to position the layer between two elastic layers so that the strength-enhancing layer does not substantially contact the nonwoven facing. In this manner, the strength-enhancing layer may avoid substantial damage during the lamination process.
