Abstract

The present invention is directed to an elastic laminate which is elastically extensible in at least one direction. The elastic laminate includes an elastic member having a first surface and a second surface opposing the first surface; and a spunbonded nonwoven layer joined to the first surface of the elastic member to form a laminate. The spunbonded nonwoven layer includes component fibers formed by a polypropylene/polyethylene copolymer. The laminate is mechanically stretched to form an elastic laminate. The present invention is also directed to a disposable article having the elastic laminate.
