Abstract:
A composition comprising a low density polyethylene (LDPE) and a metallocene-catalyzed linear low density polyethylene (mLLDPE) wherein the composition when extruded as a molten resin displays a neck-in value that is about equal to or increased by less than about 10% of the neck-in value observed when using the LDPE alone. A method comprising blending a LDPE and a mLLDPE of this disclosure to form a polymer blend having a miscibility factor of 1; extruding the polymer blend onto a substrate wherein the extruded polymer blend has a neck-in that is about equal to or increased by less than about 10% of the neck-in value observed when using the LDPE alone and wherein an amount of trim waste produced is equal to or about 10% less trim waste than the amount of trim waste produced when utilizing an extrusion coating using LDPE alone.
