Abstract: A polymeric netting includes polymeric strands and first and second polymeric ribbons. The first and second ribbons each independently have a height-to-width aspect ratio of at least three to one and a major surface that is intermittently bonded to a polymeric strand, with first and second edges symmetrically disposed on opposite sides of a center line bisecting the major surface. The netting has first and second opposing major surfaces transverse to the major surfaces of the first and second ribbons. The first major surface of the netting includes the first edges of the first ribbons, and the second major surface includes the second edges of the second ribbons. The first ribbons do not extend to the second major surface, and the second ribbons do not extend to the first major surface. Articles including the netting, an extrusion die, and a method useful for making the netting are also disclosed.
