A process for producing a filament comprising the steps of: (A) mixing in an extruder: (a) from 1 weight percent to 40 weight percent of a post-consumer recycled material as defined in ISO 14021:2016 having a density of from 0.910 grams per cubic centimeter to 0.940 grams per cubic centimeter and a melt index of from 1.0 gram per 10 minutes to 5.0 grams per 10 minutes; wherein the post-consumer recycled material consists essentially of (ai) from 30 weight percent to 99 weight percent of a linear low density polyethylene and (aii) from 1 weight percent to 70 weight percent of a low density polyethylene; and (b) from 60 weight percent to 99 weight percent 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 radian per second shear rate to 220 radian per second shear rate, wherein the viscosity is measured by the procedures described in ASTM D4440-84 and ASTM D4703; and (B) extruding the mixture of step (A) through the extruder to form a filament.
