Abstract
High density polyethylene made using a cobalt or iron complex of a selected tridentate ligand as a polymerization catalyst may be made into packaging which has advantageous properties, especially lower permeation to ambient materials such as oxygen and/or water. The packaging, such as bottles, bags and rigid storage tanks, may be formed by conventional methods.
