Have you ever had that long morning’s work or those extensive boring lectures where your mind just drifts to the next best thing? And what is that next best thing you ask? That would be your lunch. That’s right, that steaming, mouthwatering food you get during your break from all that stress during the day, and your energy source for another afternoon battle.

Isn’t it also wonderful if you have packed your food and brought it to your office or school? No more deciding where to eat or what to eat, and no more waiting in line at the cafeteria. Just take your lunch box out of your bag and you have that stomach-filling food you so looked forward to.

However, the downsides of bringing your own lunch box are that it takes away the warm mouthwatering qualities of your lunch. It becomes a bit soggy due to the condensation in the box, and the food becomes cooler than you want it to be. What a bummer. Personally, it takes away my appetite and I’ll probably skip lunch altogether, leaving me irritated throughout the day.

Why You Should Opt for an Insulated Lunch Box

You might be having second thoughts on buying an insulated lunch box. I mean, it does take a portion of your month’s budget and it also entails commitment if you plan to bring your lunch with you. I, myself, am a big non-morning person. So, prepping my lunch means waking up way before my usual wake-up time and adding a new activity on my morning routine. But the following reasons will hopefully persuade you to get your own insulated lunch box.


Let’s be real here. Purchasing an insulated lunch box will cut a small portion of your budget for this month, but think about all those take-out and cafeteria costs. It becomes cost-efficient and saves you more dollars in the long run. What’s a little effort for additional savings in your bank, right?

Environmentally Friendly

Trashed single-use food containers
Insulated lunch boxes are reusable, so you’ll avoid piling up plastic trash.

People are now switching into a more environment-friendly option for almost everything, including lunch containers. Swapping out the usual paper and plastic disposables to a reusable container is definitely a plus for me and, hopefully, for you as well. The scientists haven’t found another planet for us to live on, so we should do our fair share in saving what we can on our planet, no matter how little that share is.


If you have read our article on food safety, then you know how important it is to keep your food on a certain temperature to avoid foodborne illnesses, especially for food that you’re taking with you. Insulated lunch boxes help keep your food warm and, expectantly, away from spoilage.

Not Limited to Your Lunch

Lunch boxes aren’t just restricted to your lunch. Want a romantic picnic and surprise your special someone with your culinary skills? How about packing your own food for camping? Lunch boxes are very convenient for any occasion that you plan to take your homemade food may it be breakfast, lunch, dinner or just a simple snack.

Things to Consider When Looking for Insulated Lunch Box

The things we have listed here are only a portion of the many insulated lunch boxes and other insulated food containers that are available in the market. You probably want to check it out yourself and consider the following when purchasing your insulated lunch box, whether you are buying it for yourself or your little one.


The capacity of your container, or the size, matters most when you’re buying a lunch box. This tells you how much food are you able to carry with you. I suggest you get a bigger size lunch box so you could fit all that you need and want. A smaller lunch box limits the amount of food that you can put in it. Unless you are on a diet, then a bigger container would be better.


It is already your lunch break and you are looking forward to that homemade lunch you brought with you. Except that when you opened your lunch box, it looked like it had been shaken and tumbled with all the food being thrown around. The pasta mixed up with your veggie salad isn’t a good site at all.  That’s why sections are pretty important to consider when buying your lunch box. How many dishes do you intend to bring with you on a daily basis? How many sections do you think you need? Would you prefer a divider or would you rather have your food sectioned by layer?


This is especially important when you are bringing soup or dishes that have a sauce. You want to make sure the liquid part of your food would stay in your container and not all-around your bag. So it’s best to make sure that your lunch box is leak-proof.
