Why Use a Stainless Steel Lunch Box

Eco-Friendly & Durable Stainless Steel Lunch Boxes

A Slice of Green stainless steel lunch boxes are a great option for those looking to replace their broken plastic lunch box with a more durable, eco-friendly and sustainable alternative. Stainless steel is one of the safest materials when it comes to storing and preparing food and drink. It is easy to clean and doesn’t leach any chemicals into your food.


Another great benefit of stainless steel, especially for children, is that a stainless steel lunch box or water bottle is pretty much unbreakable. Unlike the brittle plastic versions if you drop a stainless steel lunch box in the playground you might get a dent, and worst-case scenario the lid will open, but that’s about it.

And don’t forget, that in a world where we are trying to reduce our use of plastic, stainless steel is a great environmentally friendly alternative. Yes, it’s energy-intensive to produce, and yes it is a finite resource, but steel is infinitely recyclable. Once your lunch box is no longer usable it can be recycled into something else, and stainless steel is one of the most recycled materials worldwide.

There is now a huge range of stainless steel lunch boxes available for you to choose from, not just the A Slice of Green ones, many of which have compartments so you can have lots of delicious treats without the need for additional smaller plastic boxes. We love the tiered tiffin style boxes that allow you to make savoury and sweet or salad and a sandwich without mixing them up.

There are even insulated stainless steel lunch boxes or food flasks that allow you to take hot food with you on the go and enjoy a warming stew or soup for lunch on a cold day, or keep salads fresh and cool when you don’t have access for a fridge.

When you might not want to use a stainless steel lunch box

If you are wanting to carry very liquid foods you’ll need to make sure you have chosen a stainless steel lunch box with a leak-proof seal. In many cases, this will require a silicone seal, and you will find these on most insulated options as well to keep the boxes airtight. However, some brands may use plastic for this.

Stainless steel tubs and lunch boxes are also perfect for storing leftovers in the fridge or even the freezer (just make sure you leave a little space at the top). And provided you check there are no plastic components you can even reheat food in the oven. However, if you’re a fan of reheating your food in the microwave you’ll have to remove it from your stainless steel container first.

Stainless steel boxes, like stainless steel bottles are also quite bulky, which can be a negative depending on the occasion. Yes, they are great for stopping your sandwiches getting squashed in your bag but once you’ve eaten your lunch they still take up the same amount of space. If space is an issue a fabric lunch bag or a sandwich wrap can be a great option. In the same way that collapsible bottles are super handy when you are travelling.
