ABSTRACT:
Described is a polymeric coextruded multilayer web, the web comprising: at least two layers that are discontinuous in the cross-web direction, each layer comprising a plurality of distinct phases that are substantially continuous in the down-web direction; and at least one layer that is substantially continuous in both the cross-web and down-web directions; wherein said web has an x-axis that is in the cross-web direction of the web, a y-axis that is in the down-web direction of the web and a z-axis that is in the thickness direction of the web, and wherein the substantially continuous layer(s) lacks weld lines in the y-z plane of the web.
