Abstract

Stretch blow molded articles, e.g., thin wall containers, are made from a polymer blend comprising at least 70 percent by weight HDPE and at least 10 percent by weight LDPE based upon the total weight of the polymer blend. The HDPE/LDPE blends used in the practice of this invention provide increased melt strength resulting in a wider processing window.
