What are bisphenols and why do we want to move away from using them?
Bisphenols are a group of chemical compounds characterized by two phenol groups, of which bisphenol A (BPA) is the most well-known. For decades, BPA based epoxy resins have been used to manufacture coatings for the protection of metal can packaging. In recent years, BPA and the class of bisphenols have become a concern for our customers, as regulatory scrutiny became more intense. We are among those in the industry that have developed new solutions free of BPA and bisphenols, including metal can packaging, and are currently evaluating a switch to alternatives.
How will a bisphenol-free future affect packaging for cans?
With tighter regulations on the horizon, the metal can packaging industry will continue to face challenges in 2023 and beyond. The European Food Safety Authority (EFSA) is expected to issue its latest regulatory verdict about tolerable levels of BPA based on further scientific assessment and public consultation. The outcome can only mean more restrictions on the use of BPA-based coatings in food and beverage contact products in the EU.
We know we can move away from not only BPA but all bisphenols for food and beverage contact materials. Bisphenols – of any kind – are no longer required to create coatings for metal can packaging.
As regulations tighten in the next year or two, manufacturers will need to make the transition. Can-makers will be working with their trusted coatings partners over the coming months to migrate much faster towards a bisphenol-free world.
