Abstract

Improved injection-molded LLDPE articles, especially those having a wall thickness in the range of about 0.15 mm to as much as 1.5 mm, are prepared using an LLDPE containing a sufficient amount of at least one C.sub.5 -C.sub.12 1-alkene copolymerized with the ethylene to provide a density in the range of 0.91 to 0.945 g/cc, a melt flwo rate in the range of 60 to 200 g/10 minutes, and an I.sub.10 /I.sub.2 ratio of 7.2 to about 18. Articles such as lids and containers are prepared having improved properties.
