We’ve discussed non-toxic dinnerwarecookware, and even cleaning products in previous articles, but how about non-toxic food storage containers?

Whether we’re storing our leftovers from tonight’s dinner or we’re meal prepping for the week, our food spends a lot of time cooped up in containers.

It’d be a shame after using non-toxic cookware or serving food on safe dinner plates only to have your food tainted with toxins by storage containers.

But this is exactly what CAN be happening in your kitchen.

In our never-ending pursuit to live a healthy lifestyle, we should not overlook non-toxic food storage containers.

This post will see our top best picks of healthy food containers, but before that, we need first to discuss plastic.

Seemingly innocent plastic food storage containers are sneaky kitchen items that can be damaging to our health.

How so? That leads to our first question…

What Are the Dangers of Plastic Containers for Food?

Dangers of Plastic Containers

Chances are you have a whole kitchen drawer or cabinet full of plastic food storage containers. They’re lightweight, inexpensive, store quickly, and are very convenient. Sounds great, except that misuse can cause damage to your health. So, what are the dangers of plastic containers for food?

Let’s talk about it.

Manufacturers might use one of several types of plastic to make food storage containers.

Some are safer than others, but you never honestly know. Even some quoted as “safe” can become dangerous when exposed to specific stressors.

These stressors include heat from hot food or microwaving, scratches in the plastic, and UV sunlight radiation.

When exposed to these stressors, your plastic containers can leach out chemicals such as Bisphenol A (BPA) and Phthalates. These substances then migrate into your food, finally landing inside your body when you eat your lunch.

BPA is a chemical used to harden polycarbonate plastics and epoxy resins.

Sometimes, these plastics get used in containers that store food and beverages.

BPA concerns us because it has Estrogenic Activity (EA), meaning it mimics the female hormone estrogen in the body.

According to studies, EA chemicals are linked to health issues like adverse effects on the heart, brain, and child developmental problems.

Early childhood exposure to BPA is linked to a study of ADHD behaviors. These behaviors include inattention, hyperactivity, and depression for boys and girls.

Phthalates are chemicals used to make plastics more flexible and harder to break.

Phthalates are considered an endocrine disruptor and exposure can cause cancer and negatively affect the human reproductive system and brain development.

With the possibility of these chemicals ending up in yours or your child’s foods, it’s best to avoid plastic containers overall and skip to our section on the best non-toxic food containers.

It might be difficult for you to avoid plastic altogether, as plastic container usage is vast.

If that’s your case, then you’ll want to pay attention to this next section where we’ll answer the question:

Are there any safe plastic food containers at all?

Are Any Plastic Food Containers Safe?

To answer the question, “are plastic food containers safe?” we need to know which kind of plastic we’re looking at.

So the short answer is – it depends.

Plastic food containers, in general, should be avoided. Still, this section is for those who have no choice but to use plastic and want to avoid the more dangerous plastics.

The first thing you’ll want to do is to check the recycling number on the food container.

To check, flip the product over and look for number’s 1-7 surrounded by a triangle made of 3 arrows, known commonly as the recycling symbol (see image above.)

Plastic products labeled with numbers 1, 2, 4, or 5 generally do not contain BPA.

Products with numbers 3, 6, and especially 7 are most likely to contain BPA.

Items labeled number 7 and/or have the marking “PC,” are polycarbonates. With these kinds of plastic, BPA is used to provide some “give” to rigid plastics to reduce cracking and breaking.

If a plastic product is rigid and transparent — like a reusable food storage container — odds are good that it’s a polycarbonate that may contain BPA.

Softer, flexible, and opaque plastics are usually not polycarbonates and less likely to contain BPA.

Just always be sure to look for labeling.

Since the 1950s, companies have used BPA in plastic, so many older plastic containers are more likely to contain the chemical. This is because less information was available on its dangerous side effects at the time.

Other older containers might not even have recycling numbers embossed onto them.

Old plastic containers also wear out and, in turn, leach more chemicals into foods.

It’s best to discard all your old plastic containers altogether for this reason.

Even for newer containers, you’ll want to check the recycling numbers listed above.

Some key considerations when using these plastic containers are:

  • Do not microwave or otherwise heat food in any plastic container.
  • Do not save or reuse commercial plastic food packaging (single-use takeout containers, for example). These aren’t meant for continued reuse and can break down into your food.
  • Do not serve hot food in plastic food containers.
  • Do not wash these food containers in the dishwasher as the heat will degrade the plastic.

If you have to use plastic containers, the bottom line is to check its number and follow these precautions.

If you’re able to purchase new non-toxic food storage containers, then that is your best bet!

What Are the Safest Food Storage Containers Made From?

With plastic out of the way, now we can discuss the safest food storage containers to keep your food free of toxins.

Generally, these containers are glass, stainless steel, silicone, or ceramic. Each of these materials is non-toxic and free of the previously mentioned plastic toxins.

Although these materials are more expensive than plastic, their safety and functionality ultimately make them the smarter investment.

Not only safer, but these materials also have some other unique benefits over plastic.

Before the next section, let’s do quick pros and cons of glass, stainless steel, silicone, and ceramic storage containers.

Then, you’ll see our favorite non-toxic food storage containers made from all four materials. Something for everyone!


Glass is an all-time favorite material for food storage containers due to its toxin-free, non-porous surface and versatility!

Most of the time, glass food storage containers are soda-lime glass. This glass is about 70% silica (silicon dioxide, aka, sand), 15% soda (sodium oxide), and the rest lime (calcium oxide).


  • Plastic-free
  • Toxin-free
  • Microwave safe
  • Hot food safe
  • Refrigerator & freezer safe
  • Dishwasher safe
  • Oven safe although lids made from different materials might not take the heat
  • Non-porous surface – Easy to clean and doesn’t hide bacteria
  • Recyclable
  • Does not absorb food tastes or smells
  • Non-reactive with acidic foods


  • Heavier than plastics – Can be hard to travel with
  • Very fragile to shock – Requires safer handling

Stainless Steel

Stainless steel food storage containers are becoming more and more popular as people realize the incredible benefits they offer.

Stainless steel’s clean and non-porous surface coupled with its corrosion resistance make it a great non-toxic option for storing food.

Stainless is unbreakable, making it great for mischievous children, and it’s lightweight enough to be carried along on trips easily.

It is an alloy of iron, nickel, and chromium.


  • Plastic-free
  • Toxin-free
  • Hot food safe
  • Refrigerator & freezer safe
  • Dishwasher safe
  • Oven safe although lids made from different materials might not take the heat
  • Non-porous surface – Easy to clean and doesn’t hide bacteria
  • Recyclable
  • Does not absorb food tastes or smells
  • Unbreakable (Child-friendly)
  • Lightweight – Great for travel


  • Not microwave safe
  • Can be a little pricey
  • Can sometimes give acidic foods a metallic taste


Silicone food storage containers are another fantastic non-toxic option making their way into kitchens around the world.

This revolutionary material shares plastic’s desired characteristics (flexible, lightweight, easily-moldable) without the negatives like BPA, Phthalates, and other chemicals.

It remains inert (doesn’t change state or leach chemicals) even with temperatures at 400℉.

It’s unbreakable, soft, and highly flexible, making it an excellent option for kids.

Silicone is a synthetic polymer made up of silicon, oxygen, and typically carbon and hydrogen.


  • Plastic-free
  • Toxin-free
  • Microwave safe
  • Hot food safe
  • Refrigerator & freezer safe
  • Dishwasher safe
  • Soft and flexible – Great for children
  • Oven safe although lids made from different materials might not take the heat
  • Unbreakable (Child-friendly)
  • Relatively lightweight – Easy to travel with
  • Recyclable
  • Non-reactive with acidic foods


  • Low-quality silicone can contain chemical fillers
  • Although recyclable, it can be difficult to find a recycling center that handles silicone
  • Can sometimes absorb smells and tastes of food or soap


Ceramic has been used for thousands of years in food preparation/ storage and for a good reason.

It’s another very pure and natural material, made from clay and other earthen elements shaped and baked in a high-temperature kiln.

Ceramic is also non-reactive with acidic foods and can withstand very high heat.


  • Plastic-free
  • Toxin-free
  • Microwave safe
  • Hot food safe
  • Refrigerator & freezer safe
  • Dishwasher safe
  • Oven safe although lids made from different materials might not take the heat
  • Does not absorb food tastes or smells

  • Very fragile to shock – Requires safer handling

The Best Non-Toxic Food Containers

When you’re trying to get the best non-toxic food containers for your family, it’s essential to know what features you need in your containers.

Do you need a food storage container that is lightweight and leak-proof so you can travel with it?

In that case, a quality stainless steel container with air-tight lids would be ideal.

Maybe you need something that can go right from the fridge into the oven to heat up?

If that’s you, then glass or ceramic would be the way to go!

Or maybe you need non-plastic food storage containers that are still soft and flexible for your children.

Silicone shines in that department.

Whatever your need may be, this next section shows you our favorite non-toxic food containers in each of the four materials we’ve discussed…

Glass, stainless steel, silicone, and ceramic.

We’ve evaluated these products over many research hours, taking brand reputation, material quality, and customer experience reviews into consideration.

Best Non-Toxic Glass Storage Containers


Glasslock delivers the flexibility of using just one container that is microwave, freezer, and dishwasher-safe! Even the oven is no match for these, making it one of the best glass food storage containers available!

Handles temperatures from -4℉ up to roughly 450℉.

Glasslock’s food storage set is made of soda-lime tempered glass, making it non-toxic and recyclable.

These are odor-free, stain-proof, and feature water-tight easy-latch matching lids that provide more security and convenience when storing or transporting meals.

That means no more sharing your lunch with the inside of your car or lunch bag!

The transparent glass design makes it easy to identify the contents inside without having to remove the lid.

However, you should note that the lids are BPA-free plastic, so take the precautions mentioned earlier with your covers.

Also, while the containers are oven safe up to around 450℉, you shouldn’t heat your lids in the microwave, so use a paper towel or plate to cover the top to be safe.

The lids should not go in the oven either.

All in all, these are great healthy food storage containers that are leak-proof, great for on the go, non-toxic, and can be heated in the oven and microwave!

Pyrex has been a long time favorite in the world of non-toxic food storage containers since its creation in the early 1900s.

Since then, cooking trends have changed, but what hasn’t changed is Pyrex glass food storage containers’ popularity.

Why? Because of the glass’s versatility and its ability to be oven, microwave, freezer, and dishwasher-safe!

These do not have fully leak-proof lids like the previously mentioned Glasslock containers. Still, due to Pyrex’s proven track record, we had to include them on this list.

The multi-colored lids on these containers are also plastic, so you’ll need to take care not to heat with the tops applied.

Overall these are generally very safe and high-quality containers.

Because the soda-lime glass is inert, it means there are no chemicals to leach out into the food (and to you).

There are also no reactions to foods, such as in acidic dishes.

You can essentially freeze, refrigerate, bake and serve in the same glass canister and throw it in the dishwasher when done!

You can’t go wrong with this set of Pyrex food storage containers, proudly made in the USA for nearly 60 years!

These are our favorite glass food containers. Unlike the previous two, Bovado crafts their matching lids from bamboo, which prevents any plastic exposure whatsoever!

You’ll enjoy all the same benefits of glass containers, as we listed in the two examples above, with the addition of having a more Eco-friendly product.

Bamboo grows like a weed and is highly sustainable, so don’t feel bad about using bamboo products.

The specific type of glass Bovado uses is another benefit to this set over the previous two.

These are borosilicate glass, which is more durable and has higher thermal shock resistance than soda-lime glass.

That means less broken glass and, therefore, less sliced open toes!

Each food storage set includes four different sized storage containers: one 370ml, one 640ml, one 1040ml, and one 1520ml. Something for all your needs!

Prep Naturals glass meal prep containers are unique.

They are similar to Glasslock’s leak-proof containers mentioned above, but with one key difference.

These have a multi-compartment bento design, which means you get three divided sections in each container!

Divided sections make portioning out full meals much more manageable.

This design is a huge time-saver because you can prep lunches at home (I do this on Sundays), and in the mornings, grab your pre-portioned meal and head out the door!

Divided meal prep containers help you easily stick with your weight loss goals while helping you save money on ordering out.

This is a small price to pay in convenience. Still, stainless steel’s benefits outweigh any cons by providing you a super healthy and durable option to last you decades!

Collapse-it uses 100% food-grade silicone to craft their containers and lids, so there are no plastic concerns.

The lids create an air-tight seal giving you a genuinely leak-proof design, ideal for on the go!

Because silicone is inert under extreme conditions, you can take these right out of the fridge or freezer and heat food in the microwave or oven without concern!

They do not risk breaking under these rapid temperature changes like glass can.

The soft, flexible, and non-toxic nature of these food containers make them fantastic for kids and travel as they won’t break.

The final benefit to discuss is where the brand name comes from; these are collapsible!

This feature is hugely convenient for storage, especially if cabinet space is limited.

When you put these away after cleaning, press down and collapse your containers to half their standard thickness and stack them on top of one another (see image above).

That will afford you much more storage with the same amount of space in your cabinet.

Overall these are highly versatile, convenient, and some of the best silicone food storage containers that can serve your family for many years!

Picture mixing the quickness and ease of Ziploc bags with the capacity and function of typical food storage containers…

Precisely what you get are these 100% food-grade silicone storage bags!

Silicone’s soft feel makes them great around infants and young children, plus they’re entirely free of any hazardous materials.

They are not flimsy like Ziploc bags and are sturdy enough to stand on their own, making them great for snacking right out of the container!

These bags feature a removable slider that locks together the top of each bag, securing it and making the bag fully leak-proof!

There are three sizes in this 10-piece set, so you’re covered for any need.

This breaks down to two small bags (500ml/ 16 oz/ 2 cups)two medium bags (1L/ 30 oz/ 4 cups), and two large bags (1.5L/ 50 oz/ 6 cups)

You can store foods in the fridge or freezer and go right into the microwave or oven without any worry. You can’t do that with plastic Ziplocs!

These bags are resistant to both hot and cold because silicone has a high melting point and is shockingly stable at both temperature extremes.

Each silicone food storage bag is conveniently marked with volume indicators, allowing you to measure out servings as you would in meal prep, for example.

When you’re all done, you can wash them by hand or throw them in the dishwasher.

The list can go on and on with unique benefits and features, so I urge you to check these out for yourself!

Best Non-Toxic Ceramic Storage Containers


You might be familiar with Le Creuset from our previous article on non-toxic cookware.

They are a premium French cookware manufacturer best known for their colorfully-enameled cast iron cookware.

Well, they also make non-toxic food storage containers!

Le Creuset uses non-toxic ceramic to craft their high-quality stoneware canisters. They are safe to use in the microwave, freezer, refrigerator, dishwasher, oven, and broiler.

Ceramic is generally able to withstand higher temperatures than glass and remain in use longer.

The nearly-nonstick enameled surface is easy to clean, scratch-resistant, completely hygienic and will not absorb odors or flavors.

Le Creuset storage containers are reliable, durable, and resist staining, chipping, and cracking.

These sleek, colorful canisters come with a tight-sealing beechwood lid that allows for easy stacking on the counter or in cabinets.

They’re available in five different sizes and multiple colors for maximum storage efficiency and style.

Air-tight silicone gaskets and a hard-wearing enamel finish make these canisters as functional as they are beautiful.

Great for storing leftovers or keeping dry food fresh like nuts and oats.

Be careful if heating food with the lid on, though, as they are wood.

Yes, Le Creuset is a little pricey but considering its quality, you get your money’s worth.

Not just in product performance, but Le Creuset stands behind the sale, providing you a 10-year warranty on their stoneware products for any faulty workmanship.

Le Creuset offers a variety of sizes and colors.

This next ceramic food container is very similar to the Le Creuset option above, but at a more affordable price point without sacrificing much quality.

Le Creuset is the better option, but these are still popular and highly-rated ceramic jars.

Perfect for storing and preserving various ingredients, including preserves, jams, chutneys, rice, sugar, flour, tea, coffee, spices, biscuits, and more!

Like Le Creuset, these are oven, microwave, freezer, and dishwasher-safe and have excellent thermal shock protection.

The bamboo lids with silicone sealing ring ensure an air-tight seal and no plastic near your food, which is a plus!

Like the wooden Le Creuset lids, you should take care when heating food not to damage your lids.
