PFAS — per- and polyfluoroalkyl substances — are synthetic chemicals found in thousands of everyday products. They're in non-stick coatings, food packaging, waterproof clothing, and yes, most food containers. Scientists call them "forever chemicals" because they don't break down in the environment or in your body.

On August 12, 2026, the EU's updated food contact materials regulation comes into force — restricting PFAS use in any product that touches food. It's the most significant chemical safety legislation in years. Most brands are scrambling to comply. STAK was already there.

We didn't build STAK because of the ban. We built it because the problem was obvious and the market wasn't solving it. Borosilicate glass bodies. PFAS-free Tritan lids. Zero compromises on what goes near your food.
