1. A micro-layer tubular extrusion product, comprising:
one or more solidified ribbon shaped flow streams each including multiple laminated flow streams arranged to flow in parallel, each solidified ribbon shaped flow stream having two ends, the two ends are opposing surfaces that are parallel to the flow stream,
wherein one end of one solidified ribbon shaped flow stream is bonded to the other end of the one solidified ribbon shaped flow stream or an end of another solidified ribbon shaped flow stream to form a bonded one or more solidified ribbon shaped flow streams including a bonded seam where the one solidified ribbon shaped flow stream is bonded to the other end of the one solidified ribbon shaped flow stream or the end of another solidified ribbon shaped flow stream and the bonded one or more solidified ribbon shaped flow streams form the micro-layer tubular extrusion product, the ends of the respective ribbon shaped flow streams which are bonded to the one solidified ribbon shaped flow stream or another solidified ribbon shaped flow stream being the opposing surfaces that are parallel to the flow stream which are adjacent to and in direct contact with one another,
wherein at least one bonded seam is rotated around a central axis of the tubular extrusion product, wherein the central axis is parallel to the flow stream.
