The container is from Amcor Rigid Plastics. The unique, all-natural beverage is called Greater>Than, and the startup company behind it is based in Highland Park, IL. Filling is done by contract packager Winona Foods.

“The PowerFlex bottle is unique,” says Mark Sider, co-founder of the startup beverage marketer. “It’s taller than other 20-oz sports drink containers. It’s clean-looking, and it gives us a big edge in terms of providing eye-catching shelf appeal.”

Amcor’s stock PowerFlex bottle features a patented panel-less design that takes hot fill (185 deg F) bottle options to a new level. Amcor’s structural design eliminates the panels, and unlike competitive containers, provides a large, completely smooth, and rib-less label panel. Amcor used design and manufacturing techniques to create a patented bottle that absorbs vacuum via a specially designed base. A unique diaphragm within the base draws upward as the liquid cools. It has the geometric characteristics to enable the inverted cone-shaped diaphragm to deflect upward as the vacuum is created.

The stock PowerFlex bottle has a 38-mm finish and a paper label from Fort Dearborn. Greater>Than is currently sold in the Chicago area and online at
