PPG has developed an enhanced internal spray coating for the infinitely recyclable aluminum beverage can. The spray coating uses no bisphenol-A (BPA) or bisphenol starting substances and provides more robust application properties.
The Innoval® Pro spray coating is a next-generation, high-performance acrylic coating that draws on PPG Innovel’s nearly ten years as the market’s most widely used non-BPA internal beverage spray coatings. The company estimates that these coatings have been used on more than 220 billion cans in more than 40 countries to date.
Complying with all global food contact standards for consumer safety, the coating’s improved application properties provide operational benefits for can plants around the world. “The growing and dynamic beverage can industry requires solutions that satisfy all global regulations to remove bisphenols from food contact coatings while ensuring maximum can line production speeds and minimal spoilage,” said Amy Ericson, PPG senior vice president, Packaging Coatings. “PPG Innovel Pro coating is a future-forward solution that doesn’t rely on BPA or any other bisphenol starting substances while protecting both can and beverage integrity.”
Validated with the PPG SafeAssure™ protocol for safe food-contact coating development, the coating reliably supports the ever-widening range of filling goods that beverage brands want to can. It features a lower migration profile than standard epoxy and epoxy-mimic coatings, and all of the company’s internal spray coatings have achieved Platinum Cradle-to-Cradle® material health certification from the Cradle-to-Cradle Products Innovation Institute.
“The innovation goes beyond the product itself,” said Ericson. “PPG offers customers a resilient supply chain with manufacturing sites across the globe. The new coating also comes with the support of industry-leading technical and regulatory support teams, which provide on-site expertise to keep customer operations running smoothly.”
PPG sees the new coating providing a big step forward for the industry, enabling major beverage brands to more efficiently offer safe and more sustainable metal-packaged drinks that today’s consumers can feel good about.
