摘要:
A method for making an elastomeric apertured web comprises providing a precursor web comprising a laminate which is subjected to incremental stretching to form an elastomeric precursor web. A forming apparatus is provided comprising a first member and a second member, wherein the first member comprises a mating member, and the second member comprises teeth which are joined to the second member. The elastomeric precursor web is moved through the forming apparatus, wherein apertures are formed in the elastomeric precursor web material as the teeth on the second member penetrate the mating member forming an elastomeric apertured web. The elastomeric apertured web exhibits a WVTR of at least about 1000 g/m2/day.
