Amcor (ASX: AMC) has partnered with Insymmetry to develop an innovative 2oz retort bottle, addressing the growing demand for durable, shelf-stable packaging.

Designed to meet the needs of brands seeking high-performance packaging for low-acid, shelf-stable products like coffee and dairy-based beverages, this packaging solution is the first to leverage Amcor Rigid Packaging’s proprietary StormPanel technology.

Designed to withstand high-pressure retort sterilisation processes while maintaining product integrity, the bottle aims to provide manufacturers with a reliable and scalable alternative to aseptic processing.

Stellify, a beverage brand owned by Insymmetry, is the first company to take advantage of this StormPanel technology with its energy nootropic Dulce de Leche Energy and Espresso Energy wellness beverage shots.

Engineered with StormPanel technology, the bottle maintains shape and structural integrity under the extreme heat and pressure fluctuations of retort sterilisation, ensuring reliable protection and an extended 12-month shelf life with no refrigeration. The design incorporates features that preserve the round shape, while other areas are specifically designed to flex.

Utilising finite element analysis (FEA) and Amcor Rigid Packaging’s virtual reality capabilities to streamline the process, the teams refined the StormPanel design to maintain structural integrity during the retort sterilisation by selecting a co-polymer resin and optimising a one-step molding system, they ensured efficiency and scalability.

“At Amcor, we are committed to driving innovation that addresses the evolving needs of the food and beverage industry,” Amcor Rigid Packaging strategy and marketing vice-president Greg Rosati said.

“Our StormPanel innovative packaging allows beverage brands to elevate shelf-stable, low-acid products in a compact, ready-to-use bottle.”

He added that the retort process also offers a more cost-effective and time-efficient solution for manufacturers compared to aseptic processing, reducing upfront equipment investment and streamlining production timelines while maintaining product integrity.

“Amcor’s expertise in packaging innovation enabled us to develop a solution that meets our unique needs,” Insymmetry chief innovations officer Josh Cua said.

“By leveraging their advanced manufacturing technology and material science capabilities, we were able to create a bottle that not only performs exceptionally in the retort environment, but also aligns with growing consumer demand for preservative-free nutritional shots.”
