Amcor introduces the first 2oz nutritional shot retort bottle using StormPanel technology

Amcor’s partnership with Insymmetry has led to the development of an innovative 2oz retort bottle, addressing 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 breakthrough packaging solution is the first to use Amcor Rigid Packaging’s (ARP) proprietary StormPanel technology. It can withstand high-pressure retort sterilisation processes while maintaining product integrity and be market-ready.
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, which will be spotlighted at Natural Products Expo West 2025.
“At Amcor, we are committed to driving innovation that addresses the evolving needs of the food and beverage industry,” said Greg Rosati, VP of strategy and marketing of ARP. “Our StormPanel innovative packaging allows beverage brands to elevate shelf-stable, low-acid products in a compact, ready-to-use bottle.”
While an ideal product for the end-user, 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,” said Josh Cua, chief innovations officer of Insymmetry. “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.”
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.
“This collaboration is a testament to Amcor’s ability to combine deep industry expertise with advanced engineering to address complex challenges,” said Mikey Tom, business development manager at ARP. “We are proud to deliver a solution that provides manufacturers and consumers with uncompromising quality and functionality.”
ARP’s close collaboration with Insymmetry was key to developing the innovative retort polypropylene bottle. Utilising finite element analysis (FEA) and ARP’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 moulding system, they ensured efficiency and scalability. The project’s proximity to Insymmetry’s California operations enabled rapid prototyping and promises of accelerated commercialisation.
“As a smaller company, we are truly grateful for Amcor’s trust, time and confidence in us,” said Cua. “Partnering with a global leader like Amcor has been invaluable, and we greatly appreciate the dedication of the entire team for making the impossible possible.”
