Abstract:
Articles comprising first and second coextruded polymeric nettings are described. The articles comprise a plurality of pairs of first segments comprising a first material. Adjacent first segments are joined together via a second segments comprising second material, wherein the second segments extend past the first major surface of each first adjacent segments. The articles further include an adhesive on at least one of the first or second major surfaces of the first segment. The first segments, second segments, and third material each extend continuously for at least 5 mm in the machine direction, and the first and second materials of adjacent pairs are periodically bonded together in the machine direction. A portion of some of the first segments of the first coextruded polymeric netting are engaged between some of the adjacent first segments of the second coextruded polymeric netting.
