10 Best Insulated Lunch Box Choices to Get for Your Kid Today

When I was a kid, my mom got me the best insulated lunch box.

I can’t even find the words to express how much I loved my “black princess on the shore” lunch box. To give you a fair idea, let’s just say I spent so much time gazing at her realistic face while wishing we were friends.

Looking back, I understand that my mom only wanted to keep my food warm, but what she doesn’t know is that she gave me a friend and an undying love for the beach.

So, when we got the chance to research the best insulated lunch box, I jumped on the opportunity to relive my childhood memories. Admit it — you’ve already got your lunchbox in mind. Don’t you? Well, lunch boxes have changed, and you need to know what to look for.

The Adult Quick Guide

Once you get the best insulated lunch box for your kid, you need to know how to use and maintain it properly.

We’re sure you’re already thinking, “It’s a bag that helps food to maintain its temperature, what else is there?” Well, so much else! Let’s discuss construction.

What are insulated lunch boxes made of?

The best insulated lunch box consists of multiple layers for optimum functionality. Typically, they have an outer layer made from versatile plastic like vinyl, or sturdy polymers like nylon or polyester.

Within the middle layer or base, if you will, you will find a thick layer of insulating foam composed of various materials – including polyethylene plastic, thermal fabrics, polyurethane, and other materials derived from polyester fibers.

To enhance water-resistant qualities, the middle layer is often lined atop the insulating foam with materials like foil, plastic, aluminum, or vinyl.

How can I keep my child’s lunch warm?

Many parents and guardians can attest to the fact that it’s easy to pack a cold lunch. That’s why it’s practical and convenient to opt for sandwiches, fruits, vegetables, and other non-perishable foods.

But if you’re interested in the moving toward the hot lunch route or switching it up now and then, consider using a lunch thermos or thermos lunch kit. To use, pack food while hot or put it in the thermos and microwave to make it hot. Fit it into an insulated lunch bag, and you’re good to go.

Make sure only to use foods that can be eaten warm, cold, or at room temperature.

Why put insulated lunch boxes in fridges?

Although your kiddo probably doesn’t have access to a fridge at school, you may be tempted to cool their lunch bag overnight in the fridge in hopes that the cold will persevere longer the next day.

There’s nothing wrong with this strategy, and it will surely help at least a little bit. It might not be as effective as you think, though, because the lunch box’s insulation will work to keep the inside of the lunch box the same temperature as it was when you first put it inside the fridge.

So, what’s the best way to protect cold food inside an insulated lunch box? First, we must understand that the lunch box doesn’t actively cool food – rather, it slows down the warming process. To keep the cold food cold, the best strategy is to put something inside the lunch box that will actively cool food: an ice pack!

Are they machine washable?

As our lives become increasingly hectic, the task of hand-washing can easily become bothersome. It’s no wonder that a commonly asked question regarding insulated lunch bags relates to their compatibility with the washing machine. So, let’s address the query: Can insulated lunch bags go in the washing machine?

We wouldn’t go so far to say that all insulated lunch boxes are machine washable. That’s because, while some come out looking great after a turn in the washer, others fall apart.

Typically, lunch boxes made from high-quality materials maintain their prime condition even after enduring the vigorousness of a machine.

To determine if the lunch box is machine washable, read the product description, or find the manufacturers label inside the product if there’s one. If the lunch box is inexpensive, you can throw it in the washer to see what happens. If you don’t want to risk it, stick to handwashing.

What is the best way to hand wash an insulated lunch box?

If your child’s insulated lunch box isn’t machine tolerable, you have no choice but to clean it manually. To hand wash an insulated lunch box:

1. Make warm soapy water and submerge the lunch box in it.
2. Use a soft cloth or sponge to scrub down the interior and exterior of the lunch box.
3. Rinse thoroughly under a faucet with clean water and pat down with a dry kitchen towel.
4. Make sure it air dries completely before using again.

If you can’t submerge the lunch box in water, dampen the soft cloth or sponge and wipe down. This method is also ideal if it needs light cleaning to keep fresh.

How do I keep my child’s lunch box from smelling?

The easiest way to deodorize your insulated lunch box is to dampen a paper towel with white vinegar. Leave overnight and in the morning, wash the lunch box and air dry. Alternatively, you can sprinkle baking soda to neutralize the smell.

Remind your kids to discard wrappers and scraps of food after they’ve eaten.

Now that we’ve explored their usage and maintenance, let’s jump right into the benefits of owning the best insulated lunch box.

It’s More than a Nifty Accessory

People love using insulated lunch boxes for many reasons. Here are a few of the advantages that come with investing in this personal accessory.

Temperature control

The fact is simple. If you use anything but an insulated lunch box, you’ll struggle with maintaining the temperature of your food. While some adults have the luxury of refrigerating their lunch and reheating it later with a microwave at work, most kids don’t.

The best insulated lunch box makes sure that your child’s food retains its temperature for most of the day until its ready to be consumed. You should note that room temperature food isn’t just unappetizing, but dangerous as well.

The FDA recommends that perishable foods left at room temperature for a maximum of two hours be thrown out.

Healthier lunch options

For lunch to be healthy, there’s a high possibility that it consists of fresh, perishable ingredients. And as we all know, fresh foods don’t last as long as canned and processed foods.

This explains why many parents can’t pack healthy meals for their kids as often as they’d like. With the best insulated lunch box, you’ll now have the opportunity to pack healthy lunches without ever worrying if they’ll remain consumable by lunchtime.

Reusability

Aside from any environmental concerns, one of the perks of investing in an insulated lunch box is that you save a lot of money due to its reusable nature. Although brown paper bags and disposable plastic bags may seem inexpensive, you’ll rack up some severe costs in the long term.

If you have the option to choose between a disposable bag and an insulated lunch box, it’s advisable to opt for the reusable product.

Durability and portability

High-quality insulated bags have sturdy construction to protect the contents placed inside. Due to their insulation and strategically lined foams, they do a better job of keeping food intact than other lunch bags.

Additionally, they have high-quality zips and stitching to withstand frequent usage and cleaning. A cool feature is that they are portable enough to carry alongside other stuff and lightweight enough to fit into larger bags and backpacks.

Before you think about shopping, we want to show you the importance of reading labels and product descriptions.

Toxic Chemicals Found in Some Lunch Boxes

A few manufacturers use chemicals that experts say are dangerous to your kids’ health. If a lunch box contains the following compounds, don’t buy it.

BPA

BPA (bisphenol A.) combines with other chemicals to create durable plastics. It’s derived from epoxy resins and polycarbonate plastics; the latter is primarily found in plastic containers, feminine hygiene products, water bottles, and more.

Exposure to BPA may cause various health issues, and as such, the EU and countries like China, Canada, and Malaysia tightly regulate its usage.

The FDA, however, asserts that it’s safe to use at the low levels the United States currently allows.

We believe, however, it’s best to avoid lunch boxes that contain BPA since some manufacturers fail to state the exact quantity in their products. Better safe than sorry when it comes to your child’s health.

Phthalates

These are a family of chemicals that make plastic soft and malleable. Unfortunately, researchers discovered that exposure could lead to asthma, ADHD, breast cancer, type II diabetes, and more.

Phthalates types BBP, DBP, and DEHP, have been banned from toys and lunch boxes permanently due to skin irritation and other health issues in kids.

PVC/LEAD

Other toxic chemicals to be mindful of are PVC and lead. PVC can cause cancer and liver problems in kids. When shopping, avoid products with “PVC” and “#3” labels.

Additionally, researchers explain that lead can travel out of the products into your child’s mouth to cause serious problems.

Lead is a heavy metal. And it can travel to the brain, kidney, bones, and liver. Young kids are more susceptible to lead poisoning, so it’s vital to avoid it altogether. Now, let’s show you how we selected products that are free of toxic substances and heavy metals.
