Amcor PowerPost lightweighting technology for hot-fill beverages

Amcor PowerPost technology is designed to deliver a more sustainable bottle that is up to 30% lighter and can be made with 100% recycled material.

By actively displacing the vacuum in the container after filling, the technology is claimed to deliver a bottle nearly one-third lighter, with 30% energy reduction and 30% carbon savings over most 600 mL bottles available today. It also allows for up to 100% recycled material use and provides a good consumer experience by reducing overflow spills when the beverage is opened.

The lightweighting technology for hot-fill beverages builds on Amcor’s 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, the technology can provide for increased design freedom, address sustainability goals and provide operational improvements at the fillers. Bottle labels are also able to be applied more efficiently.
