Plastipak (Plymouth, MI), a global manufacturer of rigid plastic packaging, has partnered with AriZona Beverages USA (Woodbury, NY) to commercialize the first ThermoShape system in the U.S.
The project came to fruition when AriZona challenged Plastipak to deliver a hot-fill PET package while preserving its iconic look and feel of its glass packaging. AriZona wanted the ability to be able to run on existing hot-fill lines, and offer barrier protection to maintain the great taste that the consumer has come to enjoy and expect.
Utilizing Plastipak's patented ThermoShape and DiamondClear barrier technologies, they were able to successfully deliver on all of these requests and create a smooth wall, hot-fill, extended shelf life, in a lightweight, recyclable PET container. It is able to maintain the product integrity while upholding the cost required to support AriZona's marketing and supply chain needs.
In the ThermoShape process, pasteurization renders the product microbiologically stable. The product is then filled hot to decontaminate the inner surface of the container and the closure. At this point, the container is cooled rapidly and immediately to maintain product taste and vitamin content integrity. As the result of this well-performing fill technology, hot fill products have a shelf life ranging from 6 to 12 months, similar to aseptic fill products.
PET packages with DiamondClear feature a durable monolayer structure which eliminates potential aesthetic and performance issues.
"Over the last several year Plastipak has devoted resources to broadening our hot-fill and barrier capabilities, so when AriZona came to us with this challenge, we were confident that we had the right combination of solutions to be successful," said, Tim Eppinga, Global Vice President of Food & Beverage Category.
Plastipak operates more than 37 sites in the United States, South America and Europe, with a total of over 5,000 employees.
