• 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 box options 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 for kids and adults

    How to Put Together a Plastic Free Lunch Box

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

    Which type of container suits you best? Your choice depends on whether you prefer one bento style lunch box with multiple compartments, or a combination of small and large containers.  In some cases, you may only need a wrap for your sandwich or food.

    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.  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 Onyx glass containers with a stainless steel lid and glass Ball Mason and Kilner jars.

    Onyx Leak-Proof Divided Container

    These are great for those that prefer round stainless steel containers. The silicone creates an airtight seal so you can add all the messy foods you like, and you can take out the divider to make one big meal. This also makes the container easier to clean.  Also pair with a small dipper seen below.

    Onyx airtight, leak proof round containers also come in other round varieties without the dividers.

    Onyx Small Container / Dipper

    Cheeki Leak Proof Lunch Boxes

    Planetbox Lunch Boxes

    Bamboo Cutlery

    Bamboo cutlery or a spork made of 100% bamboo – not only is it reusable and made of a renewable resource, but it is also compostable, so the ultimate zero waste accessory. The long prongs of the fork make it more effective than a regular plastic spork. And let’s face it, bamboo cutlery is very stylish, so you’ll want to use it on the go for everything.
