Choosing and using meal prep containers

Quick answers about lunch box and meal prep containers: microwave and freezer use, leak-proof lids, keeping food fresh and choosing the right set.

Which lunch box containers are microwave and freezer safe?
  • Plastic meal prep sets (our 7, 8, 16 and 24 piece sets) are microwave, freezer and dishwasher safe, so you can cook, freeze, reheat and wash in the same container.
  • Glass meal prep containers (our 12 piece set) are microwave and oven safe, and don't stain or hold smells.
  • Clear Tritan containers (our 5, 7 and 18 piece sets) are perfect for cold lunches, salads and snacks; transfer food to a microwave-safe plate to reheat.

Always loosen or remove the lid before microwaving.

Are the containers leak-proof for soups and stews?

Yes. Our meal prep and lunch box containers have airtight, leak-proof lids, and the 16 piece set uses silicone-sealed snap-lock lids that hold soup and juice. For the best seal, let hot food cool before closing the lid, leave a little space at the top, and check the lid is clicked shut on every side before it goes in your bag.

How long does meal prep food last?

As a general guide, cooked meals keep for 3 to 4 days in the fridge in an airtight container. For longer, freeze portions in freezer-safe containers and eat them within about 2 to 3 months for the best taste. Label each container with the meal and the date, and let food cool before it goes in the fridge or freezer.

Which set and sizes should I choose?

For one person's weekday lunches, a 5, 7 or 8 piece set is plenty. For families or batch cooking for the whole week, the 16 or 24 piece sets give you more containers in a range of sizes. As a rough guide, 355–562 ml containers suit snacks, fruit and sides, while 708 ml to 1 litre containers fit a full main meal.
