摘要： Provided are ethylene-based polymer compositions, articles made therefrom, and methods of making the same. Ethylene-based polymer compositions include linear low density polyethylene prepared with metallocene catalyst, which may optionally have about 5 mole percent or less of monomer units derived from an alpha-olefin comonomer. Ethylene-based polymer compositions include blends of linear low density polyethylene and one or more very low density polyethylene compositions, one or more low density polyethylene compositions, one or more medium density polyethylene compositions, one or more high density polyethylene compositions, one or more differentiated polyethylene compositions, or other conventional polymers. Articles composed of such ethylene-based polymer compositions are prepared according to a process window, e.g., at a specific extrusion rates, which provides favorable physical properties, including tear resistance and dart drop properties. Films prepared according to these techniques exhibit physical properties equivalent to, or superior than, conventional linear low density polyethylenes prepared with Ziegler-Natta catalyst.
