Abstract
An elastic liquid impermeable laminate is disclosed having an extensible barrier film; an 8 g/m.sup.2 to 100 g/m.sup.2 elastomeric nonwoven web comprising fibers of low density polyethylene having a density less than 0.89 g/cm.sup.3 ; and an extensible cloth-like outer layer, such as a nonwoven web of spunbonded fibers. The barrier laminate can be laminated by thermal point bonding to create patterns having improved loft, excellent hand and while achieving peel strengths in excess of 500 grams.
