Amcor Rigid Packaging (ARP) has launched its PowerPost next-generation technology, which delivers a lighter and more sustainable bottle, on top of providing a better consumer experience.

According to Amcor, by actively displacing the vacuum in the container after filling, PowerPost technology delivers a bottle nearly one-third lighter, with 30 per cent energy reduction, and 30 per cent carbon savings over most other 600ml bottles available today. 

The company said it also allows for up to 100 per cent recycled material use, and provides a superior consumer experience – no more spills from overflow when consumers first open their beverage, and is the most advanced lightweighting technology for hot-fill beverages on the market today 

PowerPost builds on Amcor’s patented, vacuum-absorbing technology PowerStrap, and has two key technologies – an invertible, central post that actively displaces vacuum; and PowerStrap, which is 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, Amcor said that PowerPost offers 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, and bottle labels are applied more efficiently.

“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,” said Terry Patcheak, vice-president of R&D, sustainability and project management at ARP. 

“This next-generation innovation will improve the consumer experience, while addressing widespread commitments to reduce material use and lower greenhouse gas emissions.”
