Abstract: A tubular including a plurality of first-type layers; and a plurality of second-type layers each disposed between a pair of adjacent first-type layers, wherein the plurality of first-type layers includes at least two first-type layers, wherein the plurality of second-type layers includes at least two second-type layers, and wherein a Melt Flow Index, MFI1, of each of the plurality of first-type layers is different than a Melt Flow Index, MFI2, of each of the plurality of second-type layers, as measured at a same temperature. In an embodiment, at least one of the first-type layers and the second-type layers is adapted to provide a barrier against escape of gases, liquids, or a combination thereof from the tubular.
