AFF | Lunch boxes have been a big part of our lives, and never more so since Flora started school. She takes a packed lunch to school every day, in preference to whatever the school canteen tries and fails to tempt her with. <Sigh>. And in the interests of sustainable living, it’s important to her that she has an eco-friendly lunch box or plastic-free bento box rather than using cheap, plastic containers. Because products made of wood, metal, glass, and food-grade silicone are more durable and better for her as well as our planet.
How to Choose an Eco-Friendly Lunch Box or Plastic-Free Bento Box
So whether you’re buying a lunch box for school, work, holidays, or any other occasion, what should you look for in an eco-friendly food container? Here are a few pointers to consider:
Dimension and Weight
It’s important the lunch box you choose fits nicely in your container, bag, or backpack. The box shouldn’t lie on its side in case of leaks, and you want it to hold all your food too. If you’re walking to work or school, or bringing your lunch box on a hike, it shouldn’t be too heavy as once you add your food, the weight will become a real burden.
Material
This depends on what type of food you plan to use it for. For example, if you like soup, wooden containers may not be the best option due to possible leaks. Something to bear in mind if you’re putting your eco-friendly lunch box in the same bag as your laptop or school books. Glass is a good alternative, although much heavier. Silicone or stainless steel might well be the perfect choices here.
Safety Lock
There are 3 different safety locks; snap lock, latch lock, or using an elastic band. A snap lock is what you usually see on plastic food boxes, where the lid snaps to the body. The latch lock is more common in glass and metal types (such as Kilner jars or bottles). An elastic band is a great choice if the container lids have rubber seals, or the food has no liquid that could leak out and make a mess.
Heat Resistance/Dishwasher Safe
If you plan to use your microwave or dishwasher, be aware that most low-quality plastic boxes bend or melt when exposed to high heat. This isn’t such an issue with a plastic-free lunch box but it’s always good to check before you buy.
Compartments
Compartments and dividers are great when you want to bring different foods for a balanced meal. You can either go for multiple separate containers or bento box style separate compartments in one container. This makes it easier to pack healthy carbs, fibre, proteins, fruit, and vegetables without your food getting all mixed up together.

These eco-friendly food boxes aren’t only useful for work or school, they’re also perfect for picnics, camping, going to the beach, and other outdoor activities. And yes, much as I love shopping on Etsy * sometimes it’s quicker and easier to find what I’m looking for on Amazon.

Wooden Bento Box *
This one is is your traditional plastic-free bento box. It’s only one box but divided into 3 compartments.

And it even comes with a pair of chopsticks for that authentic touch 🙂

Verdict on the Best Eco-Friendly Lunch Box and Plastic-Free Bento Box

Perfect for picnics and lazy lunches.
