THE PFAS PROBLEM

Most food containers are toxic

Most food containers on the market contain PFAS — toxic 'forever chemicals' that leach into your food. The EU is banning them from August 2026.

We didn't wait for the ban. STAK is PFAS-free by design, not by regulation.

Frequently asked questions

What makes STAK different from other food containers?

STAK is built on four pillars: PFAS-free materials that keep toxins away from your food, a modular stackable design that goes from fridge to bag in seconds, premium aesthetics you actually want on your desk, and durable construction using borosilicate glass and Tritan copolyester that lasts for years.

What does PFAS-free mean?

PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals often called 'forever chemicals' because they don't break down in the environment. They're commonly found in food packaging and containers where they can leach into your food. STAK uses zero PFAS in any of our materials or manufacturing processes.

When will STAK be available?

STAK launches in August 2026, ahead of the EU-wide PFAS ban. Join our waitlist to be the first to know when we go live and get early access pricing.

What materials do you use?

Our containers use premium borosilicate glass for the body — the same material used in laboratory equipment, chosen for its durability and purity. Lids are made from Tritan copolyester, a BPA-free and PFAS-free material that's shatter-resistant and dishwasher safe.

Do you ship internationally?

We're launching in the EU first, with international shipping to follow shortly after. Join the waitlist and we'll notify you when shipping is available in your region.
