Abstract: The present disclosure provides a linear low density polyethylene composition, tapes, fibers and filaments, artificial turfs, and method of making the same. The linear low density polyethylene composition according to the present disclosure exhibits each of the following properties: (1) a CEF fraction from 70 to 90° C. of equal to or greater than 80% of the total CEF fractions; (2) a melt index, I2, measured according to ASTM D 1238 (2.16 kg@190° C.), in the range of equal to or greater than 2.0 g/10 min and equal to or less than 5.0 g/10 min; and (3) a melt flow ratio, I10/I2, of equal to or less than 6.7.

Abstract: Artificial turf filaments formed from polyethylene are provided that can have desirable properties. In one aspect, an artificial turf filament comprises a composition comprising a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition comprises a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2≧7.0−1.2×log (I2).
