A low-density polyethylene nanocomposite comprising 5 weight percent or more of at least one nanoscale filler selected from the group consisting of montmorillonite clay, silica and zinc oxide. Changes in weatherability of the three low-density polyethylene nanocomposites based on the nanoscale fillers are determined. A surface area of the nanoscale filler in the nanocomposites is from 10 m2/g to 50 m2/g.
