    Abstract: A stretchable elastic laminate including at least one nonwoven fabric layer, and at least one elastomeric material extruded as a melt onto a major surface of the nonwoven fabric to form an elastic layer bonded to the surface of the nonwoven fabric. The nonwoven fabric layer has first and second bonding zones formed on the surface thereof, which have first and second bonding strengths. The elastic layer is bonded to the surface of the nonwoven fabric such that the elastic layer forms a stronger bond with the first bonding zone on the surface of the nonwoven than the bond formed between the elastic layer and the second bonding zone on the surface of the nonwoven. The lightly bonded areas of the elastic laminate provide increased elongation in the cross direction and improved recovery after stretch, while the more strongly bonded areas provide adhesive strength. Also disclosed is a method of forming a stretchable laminate having increased elongation and improved recovery after stretch.
