Every school lunch box dilemma solved for you

Yumbox lunch box is a great school lunchbox
The start of a new school year or term holds wonderful memories of crisp, blank exercise book pages, a clean eraser, and freshly sharpened pencils! But these days, there is also the challenge of meeting the school's policies for healthy lunches and waste free lunch box packing!
One Prep school says they must have two different containers for morning tea and lunch, while another says they need to be packed in the same box… A multi-level primary school says no metal water bottles because dropped from height a stainless steel bottle is a dangerous missile… Another wants no waste at all left at school including food scraps!
Biome founder, Tracey, says what she loves about the move towards 'nude food' or waste free lunches, is that lunches can be healthier as a by-product. Less packaging generally means less processed foods, less additives, and more simple, whole foods.
It also means less money taken from a school's budget to deal with lunchtime waste, less litter blown into our waterways, and a generation of young people growing up more conscious about their impact on the environment. Wins all round!
Every day in Biome's physical stores and via our online customer service we help with the dilemmas faced by parents. So, if we don't cover your problem here, please feel free to get in touch with us at shop@biome.com.au.

Here's the top lunch box dilemmas we can help solve for you, starting with “My child's school has banned plastic wrap!”

1. No disposable plastic wrap

Thankfully, there are now many nifty reusable sandwich pouches or food wraps – brands include 4MyEarth, Keep Leaf, beeswax wraps or vegan wax wraps.

Zip-lock bags do not need to be single use with our durable reusable versions – from Stasher, and EcoPocket

Bento style box such as Yumbox or Planetbox, or any individual container avoids the need for wrapping small bits of food in cling wrap.

Ecococoon Bento Lunchboxes have been popular recently and offer a great compartmentalised solution.

Omiebox feature bright fun colours and a high quality construction to take whatever your little one can throw at it.

Bentgo are a relatively new brand that we stock, and their lunchboxes have some seriously cool features. Check them out!

2. Low cost

Ways to save money with waste free lunches:

No need to buy plastic wrap again.

Avoid snacks packed in single serve packaging such as popcorn, biscuits, fruit and yoghurt, as they cost more than buying one large amount. Divide food into small reusable containers yourself and keep a bunch on hand that are just as quick to grab.

Make your own beeswax wraps – find our recipe here.

Wasted food costs money, so involve your child in packing lunch so they are more likely to eat what they have chosen. 

3. No fridge to keep cool

All of Biome's choices are free from harmful PVC and lead, which many other vinyl insulated bags contain. Our top picks are:

Many people want a lunch bag that does not go smelly or mouldy after a few uses. Often this is due to the condensation inside the bag - ask your child to keep the lunch box sealed/closed up to keep it as cool as possible until they get home, then at home open it up right away, wipe it out with vinegar and water and leave open to dry in the sun or fresh air.

See our range of ice packs without toxic blue goo inside.

4. Sports water bottle that does not leak

Water bottles with a screw top such as Klean Kanteen do not leak if screwed fully closed, but some kids prefer more of a sipper or sports top.  The Klean Kanteen with the sports top do have a small air release valve that will leak if laid on its side.

The new Cheeki Adventure Bottles come in 600mL and 1L sizes, shown below:


For young children the EcoCocoon insulated stainless steel or Contigo plastic bottles or Themos Funtainer insulated sipper bottles.

Another great large leak-proof water bottle is the EcoVessel Boulder. This is a premium insulated bottle with a tight seal around the lid.

5. Needs to fit a sandwich

Using a sandwich wrap or reusable ziplock is a good option as it keeps the sandwich safe in whichever lunchbox you choose.

If you are looking for a bento-style divided lunchbox with a compartment big enough for a sandwich, some good options are Ecococoon 5 compartment bentos, Planetbox Rover or Bentgo Kids Leakproof. Note that sandwiches may need to be cut or on the smaller side to fit properly in these compartments.

Some other containers that will likely suit your needs:

6. Needs to fit a whole piece of fruit

An average size Pink Lady apple or a peach or mandarin is about 7cm high. Most choices will fit a cut up apple or orange, but for a whole small apple or orange, the deepest is Cheeki Hungry Max 1.6L at 8cm deep. It has no internal dividers so you will also need reusable wraps or more small containers inside. See it here:

U Konserve To-Go Square Container 1.4L is 7.5cm high. 

Biome 1200mL Good to Go container is 9 cm high, so will fit a whole piece of fruit.

B.Box Lunch box is 6.5cm high. 

An alternative is to use a soft lunch bag, such as PACKiT or SoYoung. While these will not provide the same amount of protection to their contents, they are typically larger in volume and provide you with more flexibility in how you pack your lunch.

If none of these options float your boat, you might have to pack cut up fruit. For this purpose, we recommend the Biome Good to Go 480mL stainless container as it is leak-proof and will contain all the sticky fruit juice!

7. A lunch box that does not leak

  • Go Green lunch box – completely leak proof with an easy to use lock on the outside which ensures a seal for the internal sections.
  • Klean Kanteen Food Boxes - are leak proof. Buy as a set for the best value!
  • Bentgo's Lunchboxes are all good at stopping spills or leaks.
  • U Konserve stainless steel nesting trio – the lids on these containers are leak proof, though only suitable for older children as they are tight to close. The whole U Konserve range is good at preventing leaks.
  • Yumbox – is not leak proof for watery foods such as watermelon, but it is suitable for foods with the consistency of tomato sauce, hummus, yoghurt, and veggie dips. 
  • All our insulated food jars are leak proof and are perfect for keeping food like pasta warm, or yoghurt and fresh fruit cool until lunch time.

8. Leak proof with no plastic at all

With all stainless steel containers there is still a need for a small silicone seal to provide the leak proof function. Food does not however touch this seal.


  • Bentgo Microwavable Stainless Steel Containers
  • Biome Good to Go Stainless Steel Containers are all leakproof.
  • Onyx stainless steel containers - particularly the little Onyx dipper pictured here is very handy.
    • Kilner Glass Food on the Go Jar 1 Litre or 500ml or Glass container with glass lid.
    • Not completely leak proof, but pretty tight – Green Essentials Triple Layer Bento Box 1500ml
    • Planetbox – designed to keep foods from touching (some crumbs may transfer), however it is not leak proof. The dippers have a silicone lid and are leak proof. They come with the Planetbox complete kit, or sold separately.

    9. Lunch boxes that can be put in the dishwasher

    10. Are replacement parts available?
