    Abstract: Embodiments of the present invention include a heat-shrinkable article, comprising a thermoset cross-linked polymeric composition, wherein the cross-linked polymeric composition comprises at least one polypropylene polymer, and at least one polyethylene polymer, wherein the composition has a polypropylene content of less than about 50 percent by weight, and a polyethylene content of less than about 50 percent by weight, based on the total weight of the cross-linked polymeric composition. A method for making the heat-shrinkable article comprises melt mixing the at least one polypropylene polymer with the at least one polyethylene polymer and at least one additional ingredient, extruding the composition blend to form an extruded material, cross-linking the extruded material to produce a thermoset cross-linked material, stretching the cross-linked material at a temperature at or above a melting point of the material, and cooling the stretched material to maintain a form of the stretched material.
