    • 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.
    • 提供的是基于乙烯的聚合物组合物,由其制成的制品及其制备方法。 基于乙烯的聚合物组合物包括用茂金属催化剂制备的线性低密度聚乙烯,其可任选地具有约5摩尔%或更少的衍生自α-烯烃共聚单体的单体单元。 乙烯基聚合物组合物包括线性低密度聚乙烯和一种或多种极低密度聚乙烯组合物,一种或多种低密度聚乙烯组合物,一种或多种中密度聚乙烯组合物,一种或多种高密度聚乙烯组合物,一种或多种分化的 聚乙烯组合物或其它常规聚合物。 由这种基于乙烯的聚合物组合物制成的制品根据工艺窗口,例如以特定的挤出速率制备,其提供有利的物理性能,包括抗撕裂性和落镖性能。 根据这些技术制备的膜显示出与齐格勒 - 纳塔催化剂制备的常规线性低密度聚乙烯相当或优于的物理性能。
