摘要： A composition for forming a filament including a blend of: (a) from 1 wt % to 40 wt % of a post-consumer recycled material having a density of from 0.910 g/cm 3 to 0.940 g/cm 3 and a melt index of from 1.0 g/10 min to 5.0 g/10 min; wherein the post-consumer recycled material consists essentially of (ai) from 30 wt % to 99 wt % of a linear low density polyethylene and (aii) from 1 wt % to 70 wt % of a low density polyethylene; and(b) from 60 wt % to 99 wt % of a virgin linear low density polyethylene; wherein the viscosity in pascal-seconds of the virgin linear low density polyethylene is no less than 0.5 times the viscosity of the post-consumer recycled material and no more than 2.0 times the viscosity of the post-consumer recycled material in the range of from 50 rad/s shear rate to 220 rad/s shear rate; a process for making the above filament composition; a filament made from the above filament composition; a process for producing the above filament; an artificial turf made from the above filament; and a process for manufacturing an artificial turf.

摘要： Embodiments of multilayer films are disclosed comprising a first layer comprising polyethylene, a second layer comprising a first medium density polyethylene; a barrier layer; a third layer comprising a second medium density polyethylene; and a fourth layer comprising polyethylene. The second layer may be positioned between the first layer and the barrier layer. The barrier layer may be positioned between the second layer and the third layer.
