Why choose a stainless steel lunch box for kids? Two words: Toxic cocoon.

Does this thought sound familiar?…

“I doubt this PB&J nestled in a flimsy Ziploc on a smoldering summer day benefits my kid’s health.”

Well, you’re correct.

In fact, those “toxic cocoons” leach bizarre chemicals into your kid’s food.

Substances that can throw a wrench in brain development.

Plus, leaching “fast-forwards” after every steamy dishwasher cycle.

But, with a kids’ metal lunch box, you’ll win back some sanity (and health).

So in this post, you’ll discover a stainless steel lunch box for kids that’s right for your child. We hunted around to bring you a “Top 5” list (#4 is my favorite).

But first, I’ll take you through (vital) considerations to help you select the right option from the list.

Anddd before that, you’ll see why some plastics are worse than others (and how to audit your current lunch gear).

In a hurry? Click any section on the list below to jump straight there.

Let’s get started.

Why You Need to Ditch the Evil Plastic Kids Lunch Box

Evil-Plastic-Kids-Lunch-Box

When you search for the best stainless steel lunch containers online, what happens?

You’re met with a vast array of kids’ lunch boxes.

A billion styles, mostly all with a few plastic parts. Here’s why that’s an issue…

Plastic lunch boxes leach BPA and other chemicals when “stressed.”

And no, not dealing with a psychotic boss, stressed.

Stressed meaning: heat from hot food/ microwaving, scratches, and sunlight.

Even more disturbing, some plastic types expose your family to higher risk…

Here’s how to tell if your plastic is a “high-level hazard”

recycling number graphic
Source: wikiHow

Flip the lunch box over and browse for numbers 1-7 surrounded by a triangle (made of 3 arrows). Aka, the recycling symbol.

More often than not, numbers 1, 2, 4, and 5 do not contain BPA.

But numbers 3, 6, and especially 7 often do.

Plastic labeled #7 and/or show the marking “PC,” are polycarbonates. This stuff contains BPA to add “give” to the rigid structure (to make more resilient plastic).

And guess what…

BPA-free means about as much as an empty promise from a toxic lover.

Research from NCBI shows “BPA-free” plastic shares the same risk as BPA.

So, do yourself a favor and grab a stainless steel lunch container. You’ll rest easier tonight.

Now let’s explore several other benefits of a stainless steel lunch box for kids.

Benefits of a Stainless Steel Lunch Box for Kids

Stainless-Steel-Lunch-Box-for-Kids-why-choose-graphic

Sure, a metal bento box costs a little more than plastic.

But, I know you’re the kind of parent who wants what’s best for your kid.

So, make the modest investment in stainless steel; it’s worth it.

Here’s why:

1) Stainless steel lunch boxes will last a lifetime.

A smarter buy compared to cheaper plastic containers, which fall apart over time.

So, you stretch your dollar with steel – no more replacing a zillion cracked plastic containers.

2) Stainless steel has a non-porous surface. Bacteria don’t have the chance to collect in tiny crevices.

Instead, germs get annihilated by the dishwasher or sponge. Steel stays clean as a whistle.

Hence, why surgeons use stainless steel instruments during procedures.

3) Stainless doesn’t stain or absorb odors. Stainless steel laughs at the almighty tomato sauce.

So quit spending your evening scrubbing stains!

Plus, stainless steel containers don’t warp with heat (like those pesky plastics do).

BUT keep in mind – stainless won’t rust or corrode WHEN IT’S THE RIGHT TYPE OF STEEL

How do you know?

How to choose the right steel type…

stainless steel shopping example

ALWAYS make sure you see “made from” one of the following: “18/0,” “18/8, 18/10, or 304-grade/ 310-grade steel” written in the product description.

Cough…Or just choose one of the 18/8 steel lunch boxes on this page… cough.

Cheaper 201-grade stainless, for example, will leave rust in your kid’s food. Yuck!

4) Kids’ steel bento boxes prevent mess. Here me out…

Have you ever opened your kid’s lunch bag to discover what looks like an active crime scene?

“Leak-proof” stainless steel lunch boxes won’t ever crack and explode like plastic food containers. (We’ve got three leak-proof options below.)

So, less mess and reduced stress!

Now, let’s move on to the factors you must consider before picking your stainless steel lunch box for kids…

How to Pick the Best Stainless Steel Lunch Containers for Kids… first time around

Picking-the-Best-Stainless-Steel-Lunch-Containers-for-Kids-graphic

Don’t make a hasty decision.

Before you decide on a kids’ metal lunch box, consider the following…

1) What’s your child’s age? Or his/ her level of mischievousness?

For younger, more accident-prone children, choose a leak-proof stainless steel lunch box for kids.

Keep in mind; some kids practice more care than others. They won’t demand a secure/ spill-proof stainless lunch container (as desperately).

2) Consider means of transport…

Does your child carry their lunch along to school/ daycare with a backpack?

You’ll need a container that’s stackable, compact, and spill-proof.

No backpack? You’ll need either a metal lunch box with handles on top or a separate insulated lunch bag.

3) How about a “picky toddler” lunch box for “my food can’t touch” phases?

Choose a stainless steel lunch box with compartments to separate the meal.

Takeaway

Now, I don’t want to bore you to death, only to get your mental juices flowing.

Think through all the exact features you need.

Now, let’s start by looking at the top leak-proof stainless steel lunch boxes out there…

Oh, by the way… The unisex options below are suitable metal lunch boxes for boys and girls!

Just trying to make this easy-peasy…

Alright, we love stainless steel bento boxes and all… But have you considered the best snack containers for toddlers?

Now, I don’t know about you, but I’m sick of jumbled messes of plastic Ziplocs and snack containers.

What if one set can do it all?

Well, say hello to Brooklyn Bento’s stainless steel lunch containers/ snack tins!

You get four handy sizes in one set – all shaped from robust 18/8 stainless with leak-proof, food-grade silicone lids.

That’s right, no nasty spillage!

And real silicone with happy colors, not cheap, plastic-containing “stuff” from other brands.

The largest container holds 21oz, great for sandwiches, salads, and a dozen other uses.

2nd largest holds 13oz, great for soup, perhaps. “You’re welcome,” says the leak-proof lids.

The third holds 7oz, perfect for snacks. And the smallest holds 1.5oz, great for condiments and salad dressing.

Each soft and flexible lid pops on and off easy – perfect for kids.

Plus, the lightweight containers couldn’t be any easier to carry in a bag.

Have an issue? Brooklyn Bento protects you with a no BS warranty – just in case (you have to quick-register on their website).

The kind and sincere owners will help you out if, let’s say, you lose a lid.

So, why wait another day? Ditch the health/ planet-destroying plastic and breakable glass today – check out Bklyn Bento.

Divided Stainless Steel Lunch Box with Stainless Steel Lids

Let’s look at two divided metal bento box options.

Anyone who has picky kids knows different foods absolutely, 100% cannot touch!

Well, thanks to the divided sections, these stainless steel lunch boxes will delight even the pickiest kiddos.

But there’s a catch…

The first container won’t prevent leaks. So, it’s best for older kids (or less mess-prone children).

The second, though, has a tight-enough seal to stop liquids.

With these bento’s, you can separate the main entree and sides in one box rather than several.

So you’ll gain chill-time by using one container instead of loading/ cleaning 2-4 after work.

LunchBots Metal Bento Lunch Box (For Small Kids)

Ditch plastic snack baggies. Instead, grab this heavy-duty, solid 18/8 stainless steel lunch box with compartments (three sections)!

Yup, no nasty chemicals, stained compartments, or a busted mess of plastic (and wasted cash) from rough play. In other words, you’ll rest easier at night.

In fact, one reviewer couldn’t tell the difference between the brand new LunchBots she bought and her (older) first set after 1.5 years of daily (kindergarten) abuse.

Talk about getting your money’s worth.

Also, talk about low-maintenance… Just hurl this thing into your dishwasher, and it comes out sparkling like new.

Keep in mind; this steel lunch box measures 6” x 5” x 1.75.”

Small, but a great size for young toddlers and compact enough to take anywhere.

Stuff your bento in any lunch bag or small backpack compartment – anywhere it fits.

Use this as a metal sandwich container (half-sandwich)… Or store fruits, crackers, veggies, or cheese cubes while on-the-go, at school, on a hike, or during family car trips.

But, the divided sections won’t prevent leaks. So pack dry foods only. Pick a spill-proof box above for wet foods.

Need something bigger? A bento with extra (or fewer) compartments?

LunchBots offers a vast selection of styles and sizes in their storefront!

Overall, LunchBots has a 10-year history of producing quality stainless steel lunch boxes. Plus, they protect your investment with a painless warranty, just in case!

But enough about LunchBots, now it’s your turn. Check out this container!

The Clean Lunch’n stainless steel bento box is my favorite option on this page. Here’s why…

First, this all-in-one stainless steel lunch box can pack a serious meal.

Use its double-chamber bento design with adjustable divider to hold a full sandwich, plus fixings and sides

Without needing separate containers, clutter, and sink space.

Picky eaters? The clever divider keep food separated, plus the steel stays cooler than plastic. And you can adjust how large or small to make each compartment, depending on the meal.

Of course, shaped from tough 18/8 stainless, so you can ditch rust and rid your family of cringeworthy plastic.

The steel remains unbothered from scalding hot food (unlike plastic). Instead, you’ll upgrade your family’s health and quit burning cash on breakable plastic!

The trouble-free (kid-friendly) clamps on each side create a tight, leak-proof seal. So, meals stay secure, even if chucked across the room like a frisbee.

For cleaning, simply toss in your dishwasher and get back to rewatching Game of Thrones for the 4th time.

You can even store leftovers in the fridge or freezer, take them out the next day, and head out the door…

A true multipurpose container to help cut down on endless Tupperware!

This lunch box measures a whopping 8″ x 6″ x 2.25,″ and holds 50oz (about 4.2 soda cans).

Handy for school lunch, picnics, road trips, toddler playdates, healthy meal prep, hiking, camping, and more.

When you demand a true insulated lunch box for kids, look no further than LunchBots’ leak-proof Thermos.

With this jar, your kid will enjoy hot, fresh mac ‘n’ cheese or soup midday at school without a microwave.

Thanks to the effective triple-insulation, food stays hot for 6+ hours and cool for 12 hours.

Maybe now they’ll actually eat the lunch you pack!

And check this out… A comfortable silicone sleeve wraps the thermos and adds a non-slip grip to prevent drops!

But what’s the primary benefit of this jar? The lid…

Most other kids’ steel thermoses have plastic lid bottoms. Here’s the problem…

Hot steam collects on the plastic, then drops back down into the soup.

Yet, Lunchbots uses a full 18/8 stainless steel design for this well-built insulated food jar!

That’s right, a stainless body, inside, and lid bottom. This way, your kid’s soup stays plastic-free.

Now, the easy-opening lid is plastic (on the outside) – but it doesn’t touch your child’s food.

This thermos measures 3” wide and 4” tall with an 8oz (1-cup) capacity – a perfect size for kids or adult portion-controlling.

Great for bringing hot soups, spaghettiO’s, oatmeal, mac ‘n’ cheese, and cold fruits/ yogurts anywhere.

Plus, no leaks, ever! Drop the jar in your kid’s backpack without worry of an epic mess.

But don’t take our word for it. Tap the button below and find out for yourself!

Bonus: Best Insulated Lunch Bag for Hot Food

Here’s the deal. None of the options above insulate food – except for the Lunchbots thermos.

But does that mean your kid can’t enjoy still-hot soup or still-cold fruit in their stainless steel bento box?

Nope.

See, you can complement any of the stainless steel lunch containers above with this bag from Bentgo.

And is this just a bag? No. You’re giving your kid a cold, refreshing drink on a white-hot summer day.

Likewise, a warm meal on a brisk afternoon that’ll stop shivers dead in their tracks.

Simply toss hot or cold food in your brand new metal bento, then slide it into this bad boy.

In fact, Bentgo’s thermal insulated lunch bag keeps hot foods hot and cold foods/ drinks chilly for 4+ hours!

Now for some specs…

This dual compartment lunch box features a roomy main section to nestle a lunch container and ice pack.

Then, a handy mesh pocket sits on top to keep snacks and drinks secure.

As a further convenience, the easy-access front pockets hold napkins and utensils!

Extra steamy day? Slip an ice pack into the interior mesh pocket to keep food colder even longer.

And you’ll appreciate how easy-cleaning and comfortable this bag feels!

With an easy-carry handle and adjustable padded shoulder strap, your kid might forget it’s there.

For fast cleaning, wipe your lunch tote clean with a damp cloth.

And for a deeper scrub, chuck this machine-washable lunch bag in the laundry to save time!
