Rigid Plastics' new patented Active Hinge™ technology is used for 16-oz PET
containers for Spartan Beverages Inc., a manufacturer of all-natural protein
Spartan Beverages' 16-oz PET bottles use 40 percent less
material and cost 20 percent less than competitive PET containers. The company
was able to meet its sustainability commitment by choosing a lightweight,
recyclable bottle that significantly reduced freight costs.
Active hinge technology incorporates a design that
elevates hot fill (185F) bottle options to a new level. Amcor's technique makes
use of horizontal hinges which exhibit vertical movement and absorb the vacuum
as the liquid cools. This technology creates a look and feel that approaches
that of a straight wall container. The active hinges provide high radial
stiffness and give the 31.4-g container excellent top load strength. In
addition, the bottles are durable, dent resistant and exhibit strong stacking
