How to Put Together a Plastic Free Lunch Box

A plastic free lunch box helps reduce the demand for plastic in our world, as well as reducing your exposure to the toxins found in many plastic lunch boxes, such as lead, BPA, phthalates and PVC.

For those trying to achieve a plastic free lunch box, it can be difficult to find lunch containers and lunch bags that do not contain any plastic parts, nor fabrics made from petroleum such as neoprene, polypropylene, nylon and PVC vinyl coated polyester.

However...Biome has sought out the best plastic free lunch boxes to help you be plastic free, every day. So read on as we share how to put together a plastic free lunch box.

How to Put Together a Plastic Free Lunch Box

To assemble a lunch box without any plastic, you will need to consider:

  • Does it need to be leak-proof? To be leak-proof, the container or bottle needs to have a silicone seal and clips to hold in place, or a screw top closure. Some people use a large stainless steel lunch box and place small leak proof containers inside for dressing and dips. With containers that are not completely leak proof, you can still use them for dips that are thick and not watery. Note: most leak-proof containers have seals made from silicone. Silicone is a type of plastic, being a synthetic polymer, but the thin silicone seal is a minimal component and does not touch your food.
  • What material? Instead of plastic, your options are metal or glass. As for metal, we recommend stainless steel of 304 or 316 grade as the safest for storing food. 201 stainless steel will rust more quickly. Other metal options include tin or aluminium. Most glass containers on the market have plastic lids, but Biome offers glass Ball Mason and Kilner jars.

For a truly plastic free lunch box, your water bottle has to be plastic free too. Our favourite material for water bottles is glass as it is easy to clean, see inside, and leaches absolutely nothing into your drink.
