Don't trust the "BPA-free" sticker

The “BPA-free” label alone doesn’t tell you if a lunch box is food-grade — you need to check the material type and the recycling code.

BPA-free just means they removed one specific chemical. It says nothing about phthalates, BPS, or other plasticizers that can also mess with you. Meanwhile, “food-grade” is a broader standard for materials safe to touch food. The two don’t automatically overlap.

Look for the recycling triangle. Polypropylene (#5) and HDPE (#2) are your safe bets for plastic. Polycarbonate (#7) is the one you want to avoid — that’s where BPA lives. Stainless steel and glass are even simpler: no plastic at all.

If there’s a print saying “food-safe” or “FDA compliant,” that’s a good sign, but it’s still vague. In the EU, look for the little glass-and-fork symbol. And if a cheap plastic container has no markings at all, don’t use it for anything hot or acidic.

When in doubt, pick stainless steel or glass. Your lunch will taste better and so will the peace of mind.
