16 Best Adult Work Lunch Boxes

Is it time for you to be heading into the office?

There are numerous benefits of taking your own lunch to work every day: it saves money, it’s better for your body and it’s better for the environment.

When you bring your lunch to work every day, you obviously save money because you don’t have to buy lunch out. Think about it this way – if you spend $15 a day on lunch, five days per week, you can save $75 every week!

Carrying your own lunch also tends to encourage you to make healthier food choices. You’ll be more likely to pack a sandwich instead of a burger, fruit instead of a chocolate bar. You can also be 100% sure of the quality of the ingredients. 

Finally, packing your own work lunch reduces the demand for takeaway packaging and waste.

Best Lunch Boxes for Adults

Adult work lunch boxes are a great way of ensuring that you have a healthy and nutritious meal at the office. They come in different shapes, sizes, and materials which makes them perfect for any occasion.

Let me introduce you to the best lunchboxes for adults!

There is a wide selection of extremely practical, adult-friendly lunch boxes, such as leak-proof lunch boxes, insulated food jars and metal lunch boxes. 

Leakproof adult lunch boxes 

A leak-proof lunchbox designed for adults is ideal because it can be placed on its side, which makes it easy to load in your backpack or handbag for work.

Leakproof lunch boxes usually come with a silicone seal over the lid that works to make the lid airtight. 

However, this does not mean that they’re not completely plastic-free. Instead, look for leak-proof lunch boxes that are BPA-free and phthalate-free.

Adult lunch boxes that are insulated

An insulated food jar can keep your lunch hot or cool all the way to lunchtime. They are an excellent choice for those who are on the go or don’t work in the office and do not have access to a refrigerator or microwave.

To keep hot food as warm as you can, preheat your food container by filling it up with boiling water prior to pouring it out and adding hot food items. 

To keep food chilled to the maximum extent feasible you can put your food jar into the freezer, with the lid removed for 15 minutes prior to adding the cold food items.

Look for insulated lunch boxes or food flasks that are BPA Free, PVC free, leakproof and simple to open.

Metal lunch boxes for adults

Lunch boxes for adults made of metal are constructed from top quality food-grade, 18/8 stainless steel. They are extremely durable, user-friendly and clean and will last for a long time. If it does get to the point of no return it is 100% recyclable.


Metal lunch boxes will not retain the smells and colours of food as plastic lunch boxes do, and they can be washed in the dishwasher. They will take the occasional bump but they could scratch or dent when dropped on the hard surface.


Most lunch boxes made of metal are not leak-proof and therefore are not suitable for foods that are very wet. Some models have an adhesive made of silicone on the inside of the lid that makes it leakproof.
