One of the challenges to hot-filled PET bottles is that ribs or panels must accommodate post-fill cooling. That can mess with labeling, the label, and its appearance. Amcor PET Packaging’s (www.amcor .com) smooth-panel PowerFlex™ 16.9-oz bottle accepts hot filling at up to 185ºF.

The domed-shoulder, patent-pending bottle features an inverted cone-shaped diaphragm molded in the base that draws upward as the liquid cools. The bottles are topped with 38-mm Extra Lok oxygen barrier closures from Alcoa Closure Systems International (www.alcoa.com).
