Materials that make sense
- Stainless steel: tough, long‑lasting, no odour. Use silicone cups for wet items.
- PP #5 plastic: lightweight, affordable; avoid heat + harsh scrubbing.
- Silicone: good for lids and snack pouches; check for firmness and no fillers.
Leakproof, realistically
- Choose one leakproof pot for yoghurt/dips instead of an all‑leakproof box.
- Pack wet foods upright. Add a small cloth to catch condensation.
Sizes per age
- Under 5: 600–800 ml, 2–3 compartments.
- 5–9: 900–1100 ml, 3–4 compartments.
- 10+ / teens: 1.2–1.4 L, add a separate snack pot.
Packing pattern
Protein + veg/fruit + whole grain + healthy fat. Keep repeats to reduce decision fatigue.
Cleaning & care
- Hand‑wash lids; dishwasher can warp seals.
- Air‑dry open. Refresh silicone with a bicarb paste if smells linger.
What to avoid
- Heavily fragranced lunch bags, PVC linings, novelty coatings that peel.
