摘要
In one embodiment, the present invention relates to an extrusion bonded laminate including an elastomeric film directly bonded to at least one nonwoven web layer substantially continuously over at least a major portion of the laminate, in which the laminate is extensible in at least one direction, and in which the elastomeric film includes a vinyl arene-containing block copolymer, and in which the elastomeric film is substantially free of a tackifying amount of a tackifier, and to a process for producing an extrusion bonded laminate. In one embodiment, the total vinyl arene content of the elastomeric film is about 30% or less. The extrusion bonded laminate is useful, for example, in a diaper tab.
