Abstract
A polyethylene article comprises crystalline polyethylene in an orthorhombic unit cell. The b-axes of the crystalline polyethylene are substantially aligned with the machine direction of the article. In particular, the Herman's index of the b-axes in the machine direction is greater than zero and greater than the Herman's indices of the b-axes in both the transverse and normal directions. The unique physical attributes exhibited by a polyethylene article having this new morphology are also described.
