Abstract
Extrusion blow mold assemblies, extrusion blow molded articles exhibiting increased strength and enhanced processability, and processes for making said articles. In some aspects, the articles produced herein can include relatively rigid bottles and other containers that exhibit high drop impact performance, while still being relatively easy to deflash. Such containers can be efficiently produced on a commercial scale and are widely usable in a variety of applications, including those in the food, beverage, cosmetic, and medical industries.
