PPG has announced the next generation of its acrylic internal spray coating for aluminium beverage cans, which does not use bisphenol-A (BPA) or bisphenol starting substances and reportedly offers enhanced application properties.

According to PPG, its INNOVEL PRO is an enhanced internal spray coating that is free from BPA and bisphenol starting substances, apparently offering more robust application properties for recyclable aluminium beverage cans.

PPG says the next-generation acrylic coating draws on PPG Innovel’s nearly ten years on the market, reportedly as the most widely used non-BPA internal beverage spray coating. The company estimates that PPG Innovel coatings have been used on more than 220 billion cans in more than 40 countries to date.

The PPG Innovel PRO coating complies with all global food contact standards for consumer safety and is validated with the PPG SAFEASSURE protocol for safe food-contact coating development, the company claims. The coating allegedly features a lower migration profile than standard epoxy and epoxy-mimic coatings, with the company adding that all PPG Innovel internal spray coatings have achieved Platinum CRADLE-TO-CRADLE material health certification from the Cradle-to-Cradle Products Innovation Institute.

In addition, the company says that PPG Innovel PRO’s improved application properties provide operational efficiency benefits for plants using the coating.

Amy Ericson, senior vice president of packaging coatings at PPG, comments: “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.

“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.

“The innovation goes beyond the product itself. 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 Innovel PRO coating is a big step forward for the industry, enabling major beverage brands to more efficiently offer safer and more sustainable metal-packaged drinks that today’s consumers can feel good about.”

According to a recent report from McKinsey, the use of BPA may be more tightly regulated in Europe in the coming years, with European Food Safety Authority (EFSA) currently re-evaluating the tolerable daily intake value. The organisation recommends that companies take proactive action in advance of regulation to ensure safe and timely substitutions of prohibited chemicals.
