Patent attributes
A composition comprising a low density polyethylene (LDPE) and a peroxide-treated metallocene-catalyzed linear low density polyethylene (pmLLDPE), wherein the composition when extruded as a molten resin displays a neck-in value that is (i) decreased when compared to the neck-in value observed when using the LDPE alone, (ii) about equal to the neck-in value observed when using the LDPE alone, or (iii) increased by <10% of the neck-in value observed when using the LDPE alone. The composition when extruded as a molten resin displays a neck-in value that is decreased by ≥5% when compared with a neck-in value of an otherwise similar composition comprising the LDPE and a metallocene-catalyzed linear low density polyethylene (mLLDPE) that has not been peroxide-treated. The composition comprises 1-80 wt. % pmLLDPE. The pmLLDPE has a melt index of ≤0.9 g/10 min, when tested in accordance with ASTM D1238 under a force of 2.16 kg.
