Amcor Rigid Packaging (ARP) has announced the creation and launch of PowerPostTM. By actively displacing the vacuum in the container after filling, PowerPost technology delivers a bottle nearly one-third lighter, with 30% energy reduction and 30% carbon savings over most 20 oz (600 ml) bottles available today.
It also allows for up to 100% recycled material use and provides a superior consumer experience – no more spills from overflow when consumers first open their beverage. PowerPost is the most advanced lightweighting technology for hot-fill beverages on the market today. PowerPost builds on Amcor’s patented, vacuum-absorbing technology PowerStrap.
The PowerPost base has two key technologies: an invertible, central post that actively displaces vacuum, and PowerStrap, the flexible ring surrounding the post. After filling, the post is inverted to actively displace vacuum inside the container and, as the product cools down, the surrounding ring flexes to passively absorb any remaining vacuum.
By eliminating the vacuum panels, PowerPost to offer increased design freedom, premium appearance and consumer appeal, while addressing sustainability goals. Eliminating the panels in the body also drives operational improvements at the fillers. Bottle labels are applied more efficiently.
Terry Patcheak, vice president of R&D, sustainability and project management at ARP said, “Our engineers have developed technology that pushes the boundaries of lightweighting in the hot-fill arena to help our customers meet their cost and sustainability needs. This next-generation innovation will improve the consumer experience while addressing widespread commitments to reduce material use and lower greenhouse gas emissions.”
