The lunch box isn't the safety feature. Your habits are.

Packing a lunch for a peanut allergy is about avoiding cross-contamination, not buying a special “allergy-proof” box. Any lunch box that you can completely take apart and wash in hot, soapy water will do the job.

The real rules are simple: read every label yourself, avoid anything that says “may contain peanuts,” and never reuse a container that has touched peanut butter without a full wash. Keep a dedicated lunch kit for the allergic kid and don’t use the same bag for other kids’ lunches. Also tell the school what you packed and remind your kid not to trade food.

For brands, you want something with no deep crevices where crumbs hide. PlanetBox and LunchBots are stainless steel and wash up fast. Bentgo and Yumbox work well too because the sections keep things separate, but check that every seal and latch comes off for cleaning.

The box isn’t what keeps your kid safe. The packing habits are.
