    摘要： Polymeric netting comprising polymeric ribbons and polymeric strands, each of the polymeric ribbons and polymeric strands having a length and a width, wherein the length is the longest dimension and the width is the shortest dimension, wherein a plurality of the polymeric strands are bonded together to form a netting layer, wherein adjacent polymeric strands in the netting layer are bonded intermittently at multiple locations along their respective lengths, wherein the netting layer has first and second opposing major surfaces, wherein the polymeric ribbons have a height-to-width aspect ratio of at least 2:1 and a minor surface defined by their width and length, and wherein the minor surface of a plurality of the polymeric ribbons is bonded to the first major surface of the netting layer. Polymeric netting described herein are useful, for example, in an absorbent article.

    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.
