Abstract:
1. A polyethylene resin having a multimodal molecular weight distribution, said resin being further characterized in that it: (a) has a density in the range from 0.925 g/ccm to 0.950 g/ccm, and (b) has a melt index (I (c) comprises a high molecular weight (HMW) component and a low molecular weight (LMW) component, and wherein the HMW component comprises at least one high molecular weight ethylene interpolymer having a density in the range from 0.910 g/ccm to 0.935 g/ccm, and a melt index of 1.0 g/10 min or lower, and wherein the LMW component comprises at least one low molecular weight ethylene polymer having a density in the range from 0.945 g/ccm to 0.965 g/ccm, and a melt index in the range from 2.0 g/10 min to less than 200 g/10 min, and wherein the at least one high molecular weight interpolymer and/or the at least one low molecular weight polymer is a homogeneous, substantially linear interpolymer.
