    摘要: An incrementally activated laminate that includes an incrementally activated fibrous web and a film having alternating first and second regions and a laminate of the film and an extensible fibrous web. The first region of the film includes a first polymeric composition, and the second regions include an elastic polymeric composition that is more elastic than the first polymeric composition. In the incrementally activated laminate, the distance between midpoints of two first regions separated by one second region is smaller than the activation pitch, and the first regions are not plastically deformed. In the extensible laminate, a tensile elongation at maximum load of the film is up to 250 percent of the tensile elongation at maximum load of the extensible fibrous web. Methods of making the laminates are also described.
