Abstract

Plastic containers are described herein that are injection molded with an high density polyethylene (HDPE) blow molding grade resin having a density of about 0.960 to about 0.965 g/cc, and a melt index of about 0.7 to about 1.0 g/10 min., at injection temperatures of about 570° F. to about 670° F., and mold cavity pressures of about 20,000 psig to about 27,000 psig. Relatively thin walled, rigid, containers, such as livestock feed containers, may be manufactured as described using about 20% to 50% less material while retaining strength and durability comparable to containers molded of HDPE injection molding grade resins.
