Can non-toxic food storage containers boost your food’s health? Consider this:
Whenever you toss food in plastic food storage containers, you get more out than you put in…
Your food sucks in bits of microplastics and chemicals, which, of course, end up in you.
So, non-plastic Tupperware makes sense.
It’d be a shame to serve healthy food on safe dinner plates only to taint your leftovers with plastic. So, it seems non-toxic food storage containers have their place in any healthy lifestyle.
That’s why we reviewed dozens of picks, then trimmed down to the top 11 safest food containers.
But, before that, there’s something you need to know about the so-called safe plastic containers… (i.e., BPA-free food storage containers)
*Hint* — they’re not as safe as you think.
So, you’ll discover how to audit your current plastic Tupperware’s risk, among other topics. This way, you score the best non-plastic food storage containers today…
And, moving forward, you’ll know exactly what to avoid.
Let’s get started!

What Are the Dangers of Plastic Containers for Food?
Chances are you (and everybody else) own tons of plastic food storage containers. They’re inexpensive, convenient, and often, we get them for free with takeout.
But here’s the problem. When these containers become stressed, they can leach harmful materials into your meal.
The heat from hot food/ microwaving your leftovers. Scratches and sunlight are two others.
And stressed plastic containers don’t unwind by the pool to relax…
Instead, they leach EA (Estrogenic Activity) chemicals like Bisphenol A (BPA) and phthalates. These chemicals help enhance plastic’s usability in containers, water bottles, and more.
Health risks of BPA & phthalates in plastic food storage containers:
Studies show these chemicals link to obesity and adverse effects on the heart and brain, to name a few.
And for children, BPA is especially troubling. Early childhood exposure links to ADHD behaviors – including inattention, hyperactivity, and depression.
Phthalates present their fair share of concerns too. The CDC found them to impact the reproductive system in animals poorly.
So, I recommend ditching all plastic containers to keep any potential hazard out of your food.
Instead, grab one of the 11 best non-toxic food containers below.
But hang on. Ditching plastic isn’t always easy or possible… Especially if you’re on a tight budget.
So perhaps you’re thinking, “C’mon! Are there any safe plastic food containers at all?! I can’t replace all my plastic yet!”
Let’s take a look.
Are Any Plastic Food Containers Safe?
To answer the question, “are plastic food containers safe?” you need to know which kind of plastic you’re looking at.
While I hesitate to say that healthy plastic containers exist, some are worse than others.
So, follow the steps below to audit your plastic—
How to check for the best food-grade plastic containers (Avoiding BPA)
The easiest way to audit your plastic container’s risk is to flip it over and glance at the recycling number.
(I.e., numbers 1-7 surrounded by a triangle made of 3 arrows – see above image.)
- The safest plastic containers for food are numbers 1, 2, 4, & 5. These are generally BPA-free storage containers & are safer for food.
- Products with numbers 3, 6, & especially 7 most often contain BPA.
- Plastic labeled #7 and/ or bearing the mark “PC” are polycarbonates. They contain BPA to add “give” to the rigid plastic, reducing cracks and breaking.
- If plastic is rigid & transparent, odds are, it’s polycarbonate & contains BPA. For example, a hard, clear, reusable food storage container.
- Soft, flexible, & cloudy plastic containers are less likely to contain BPA.
The point is to always check the labeling.
But here’s something to keep in mind:
All plastic—even BPA-free Tupperware—carries risk. The title of “BPA-free” is misleading altogether, as this plastic contains BPS instead.
And studies show BPS almost mirrors BPA’s risks, according to Scientific American.
The Bottom Line: IF you’re going to use (any) plastic container, follow these guidelines to reduce risk—
- 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 to reuse and will pollute your food with plastic.
- Do not serve hot meals in plastic food containers. Heat in a separate dish.
- Do not wash plastic food containers in the dishwasher. The heat degrades the plastic.
- If you have Tupperware that’s several years old; I’d chuck it right away. Old, worn-out plastic deteriorates into food much more easily.
- TIP: When buying sauces or other groceries that come in glass mason jars, save the jar! These make perfectly safe Tupperware alternatives.
Next, let’s explore the safest non-toxic food storage container materials.
What Are the Safest Food Storage Containers Made From?
With plastic out of the way, now we can discuss the safest food storage container materials…
Usually, the best non-plastic food containers come in glass, stainless steel, silicone, and ceramic. All four are safe and non-toxic.
Now, these containers cost more than plastic. But, their safety and durability make for a wiser investment.
So, let’s tackle the pros and cons of each.
This way, you better understand all four and gain a better idea of what to pick:
Glass food storage containers are an all-time favorite in the kitchen. We can thank their clean, non-toxic, and non-porous surface for that.
You’ll have a tough time finding a material that protects food flavor better than glass.
- Toxin-free – made almost entirely from sand.
- Refrigerator & freezer-safe.
- Oven-safe (although lids made from different materials might not be).
- Non-porous surface – easy to clean & doesn’t absorb or hide bacteria.
- Eco-friendly & recyclable.
- Does not absorb food tastes, smells, or stains – great for storing pasta sauce.
- Non-reactive with acidic foods (no metallic flavors).
- Heavier than plastic.
- Fragile – requires safe handling, especially when traveling.
Stainless steel food storage containers are rising in popularity by the minute.
Between steel’s corrosion resistance and non-porous surface, it’s perfect for food… Stains and bacteria have little chance to gather.
And, of course, it’s virtually unbreakable!
- Unbreakable, yet lightweight – great for kids & travel
- Toxin-free – made from iron, carbon, nickel, & chromium.
- Refrigerator & freezer-safe.
- Non-porous surface – easy to clean & doesn’t hide bacteria
- Eco-friendly & recyclable.
- Does not rust, stain, or absorb food flavors, smells, & odors. Stays like-new for years.
- Not microwave-safe.
- Can leach nickel or chromium into your food. (Harmless for most people, unless you’re allergic.)
- If the steel isn’t polished, it may give acidic foods a metallic taste.
Silicone food storage containers are another fantastic non-toxic option.
This rubber hybrid is soft, unbreakable, and moldable into fun designs. (Like plastic) Yet, it’s free of the negatives like BPA, phthalates, and other chemicals!
- Toxin-free- made from silicon (sand), oxygen, carbon, & hydrogen.
- Microwave & oven-safe. Silicone will not melt, leach, or off-gas chemicals when heating food.
- Refrigerator & freezer-safe.
- Unbreakable, soft, & flexible – great for children.
- Lightweight & easy to travel with.
- Non-reactive with acidic foods.
- Low-quality silicone can contain fillers.
- Although recyclable, it’s hard to locate a recycling center able to process silicone.
- Can sometimes absorb smells & tastes of food or soap. If that happens, boil the silicone in water for 15 minutes.
People have used ceramic for thousands of years to prepare and store food. And for a good reason…
It’s an all-natural, non-toxic material made from baked clay. Ceramic storage containers also withstand scorching heat and never react with acidic foods.
- Microwave & oven-safe.
- Refrigerator & freezer-safe.
- Does not absorb food tastes or smells.
- Non-reactive with acidic foods.
- A little heavy like glass.
- Fragile – requires safe handling, especially when traveling.
We’re just about there!
Next, let’s run through a few quick buying considerations. (Stuff to think about before choosing.)
Then, you’ll find the best non-toxic food storage containers in each material… An option for every purpose!
How to Choose the Best Food Storage Container for Your Needs
When choosing new containers for your family, it’s vital to consider your specific needs:
—Do you need a lightweight, unbreakable, and leak-proof food storage container you can travel with?
Pick a stainless steel container with a leak-proof seal (like this one). It won’t break or spill on bumpy rides.
—Need the best plastic-free food storage containers able to go from fridge to oven without exploding?
—Do you want soft and flexible containers for kid’s snacks? Or to squeeze into cramped cabinets?
Silicone wins again here.
—How about a non-plastic, microwavable food container for taking leftovers to work?
—Consider size & shape:
Do you need round containers? Or square/ rectangular containers?
Round containers are great for easy stacking and nesting. In contrast, rectangular containers are easier to wedge into open spaces or corners.
If you’re cramped on space, consider these collapsible containers.
—Consider easy portioning:

Best Non-Toxic Glass Storage Containers
Anchor Hocking’s TrueSeal line is one of the best glass food storage containers for leftovers and work lunches… And most versatile—
This 10-piece set includes one 1-cup container, two 2-cup containers, a 4-cup, and a 7-cup. Each has a leak-proof lid.
You can store onions and peppers in the smaller containers. Then, toss pasta, soup, stew, and entire sliced melons in the larger vessel. And with thick, tempered soda-lime glass, you’ll never worry about them cracking in the fridge.
To reheat, you can use the microwave or oven up to 425°F (218℃). You can even bake in these containers!
For work lunches, the unique TrueSeal lids snap on tight to provide an air and watertight seal. So, food stays fresh and secure on the go.
Unlike competitors, Anchor designed these lids with soft silicone edges (green part) – not plastic The silicone helps prevent cracked, leaky covers. And, of course, lowers your exposure to plastic.
In fact, only the lid’s center is plastic (clear part of lid) – so there’s minimal food contact. For glass containers with 100% silicone lids, check these out.
For storage, stack or nest in your cabinet to save space. And for cleaning, toss in the dishwasher.
Drawbacks: The lids are top-rack dishwasher-safe only. Also, you should take the covers off when microwaving – use a paper towel instead. And be careful going from hot to cold too quickly, as soda-lime glass may crack.
Altogether, Anchor Hocking’s healthy food storage containers are a safe, reliable pick. They’re made in the USA and have been for 117 years – we don’t see that every day!
Plus, you get a 5-year warranty.
Don’t need an entire 10-pack and prefer one or two pieces?
Pyrex is a long-time favorite in the world of non-toxic food storage containers – and has been for 107 years—
Over those years, they’ve perfected their glass tempering process. Once you hold these thick, sturdy containers, you’ll see what I mean.
Each versatile, 18-piece set includes:
One round 1-cup container, one rectangular 6-cup, one round 7-cup, two round 2-cup containers, two round 4-cup, and two rectangular 3-cup… All with lids.
So, you score everything you need for leftovers, work lunches, and more.
This set is great for portioned meals and pre-measured baking ingredients, too… Each lid’s volume markings make it easy!
You can freeze, refrigerate, bake, microwave, reheat in the oven (up to 425℉), and serve – all with the same canister. Then, chuck in the dishwasher to save cleanup time.
Both the soda-lime glass and multi-colored lids repel stains and odor, too. Pasta sauce? No sweat!
Drawbacks: The lids can leak. Pick #1, #4, #5, #6, or #7 on this list to prevent that. Also, you shouldn’t microwave these lids as they’re plastic.
And since Pyrex is soda-lime glass (as of 1998), try to avoid drastic temperature changes. Shock-resistant borosilicate (#’s 3 and 4) better withstand harsher conditions.
Overall, you can’t go wrong with this set of food storage containers. They’re made in the USA and backed by a 2-year warranty.
Need more than 18 pieces? Check out Pyrex’s jumbo 24-piece set here.
These are my favorite glass food containers (and most eco-friendly)…
Unlike the previous two, Bovado’s lids are solid bamboo with leak-proof silicone seals. So, 100% plastic-free food storage!
Plus, bamboo is antimicrobial, so these lids absorb fewer bacteria than plastic.
Each set includes one 51.4oz, one 35oz, one 21.6oz, and one small 12.5oz container for dips and sauces. Each with a lid—
So, a size for any need, from full entrees to leftover side dishes.
But here’s the best part:
Bovado uses thick, sturdy borosilicate glass instead of soda-lime… The same shock-resistant glass used in laboratories!
With borosilicate, you can reheat cold meals – without exploding glass or cracks! No need to let food thaw first.
Not only strong and versatile, but each container’s style makes an attractive serving piece, too.
For storage, the flat-top lids stack smoothly without wobble, saving horizontal shelf space.
And tight silicone seals prevent leaking in the fridge or your car/ bag on the go.
Drawbacks: Some customers complain about the bamboo splintering. To prevent this, wipe the covers with food-grade mineral oil once in a while.
Also, while shock-resistant, all glass can break if dropped. Grab Frego’s borosilicate glass containers with a silicone sleeve and lid to prevent breaks.
To sum up, you can’t go wrong with these glass food storage containers. They’re US-made, unlike many similar sets, plus backed by a solid 1-year warranty.
Prep Natural’s food storage set is also thick borosilicate glass. So, it’s safe in the fridge, freezer, microwave, and oven up to 500℉ (260℃)…
Yet, the glass won’t crack from rapid temperature changes when reheating.
But, two key differences set Prep Naturals apart from Bovado above.
#1. The convenient, multi-compartment bento design:
With three sections, you can pre-portion meals at home, then grab your lunch and run out the door. Doing so helps save time and money, plus makes weight loss easier.
Also, you’ll love the tight-clamping, watertight lids.
When you open your lunch bag, your food will be where it should… Secure in your container, not painted all over the inside.
#2. Prep Natural’s convenient lid design:
Each lid has a handy bonus compartment on top for storing napkins, cutlery, condiments, and more. It keeps everything where you need it – when you need it. No need to dig around in your bag!
For storage, stack your containers in your fridge or cabinets – the lids sit flat on top.
Drawbacks: There’s a small gap between the divider edges and the lid’s bottom. While nothing will leak out of the containers, food juices can mix.
Also, the covers are plastic. Yet, the lid’s food-grade silicone seals limit plastic contact with meals. For 100% silicone lids with glass, check these out.
Altogether, these meal prep containers blow cheap plastic options out of the water. Check out their thousands of positive reviews on Amazon—
Best Non-Toxic Stainless Steel Food Storage Containers
G.a Homefavor’s 18/8 stainless steel food container is a true workhorse—
With it, you gain security and mess prevention (like above)… But with 100% steel construction, you’d have a hard time breaking it if you tried!
This non-plastic food storage container measures 7.1” x 5.3” x 2.2” (18 x 13.4 x 5.5cm) and holds 40oz of food… Plenty to store complete work lunches and leftovers.
Of course, you can freeze, refrigerate, and reheat food in the oven. But unlike glass, rapid temperature changes aren’t a concern here. This container won’t crack, regardless of conditions!
But this set really shines for on-the-go.
With the lid’s silicone seal and tight clamps, wet foods and soup stay put… Even when sitting upside down in your bag.
Plus, the seal locks in smelly odor from fish and onions.
And unlike competitors, the clips on here open with ease. Even toddlers seem to have no trouble.
For cleaning, toss in the dishwasher to save time. You can also remove the silicone seal for a more thorough scrub. (See image above.)
Drawbacks: Not microwave-safe, so you’ll need to use a separate dish to reheat. Or, use this container solely for salads, sandwiches, and chilled snacks.
Overall, this non-toxic food storage container will save you cash on replacing broken items. And you get a lifetime warranty!
Looking to separate food contents?
G.a. Homefavor offers this same container with a removable divider and larger capacity. Just slide the divider left or right, depending on the size of your side dish.
Think of Bklyn Bento’s stainless steel food containers as a blend of Anchor Hocking (#1)… Mixed with G.a. Homefavor (#5).
The difference? These lids are 100% pure LFGB silicone – unlike most competitors!
(LFGB means they pass safety regulations even stricter than the FDA’s. You can’t get safer than that!)
This set includes one large 24oz container to use for sandwiches, salads, and more. Plus, one small 1.5oz vessel for dressing or sauce.
Between 18/8 stainless steel and silicone lids, this combo makes the perfect travel set. The soft, child-safe lids don’t leak.
Toss the containers in your bag before work or school, and they remain sealed – even when upside down!
For kids, food stays shielded and mess-free at school, even if dropped. One parent explained, “I shook it like crazy… trying to make them leak. Not a single drop leaked out. Totally dry!”
Drawbacks: Not microwave-safe, so use a separate dish to heat. Also, there’s no divider to separate food.
Overall, you can’t go wrong with Bklyn Bento’s non-toxic food storage containers. Between a solid 4.7 star rating and a 1-year warranty, it’s a great buy.
Want a blue lid on the large container instead? Get it here.
Best Non-Toxic Silicone Food Storage Containers
Picture Ziploc bags and non-plastic storage containers had a baby—
You’d get these 100% food-grade silicone storage bags!
Except they’re much more versatile than both Ziplocs and Tupperware separately.
For example, you can store leftovers in the fridge or freezer, then toss them directly into the microwave, oven, and even boiling water to reheat.
In fact, you can prepare and cook entire meals inside one bag. One user marinated her chicken overnight, then tossed the bag into a pot of water to cook… All without dirtying her cookware!
Each bag is 100% leak-proof, too, as the removable plastic sliders create a water and airtight seal. I’ve noticed these sliders are also easier to open and close than competitors.
You get three sizes in this 6-pack – two of each:
Use them for sandwiches; for storing meat in the freezer; to keep fruit fresh; store pasta sauce; meal prep; even as a waterproof cell phone bag!
The convenient volume markings on the sides help you portion snacks easier, too.
Speaking of snacks, these bags stand on their own, making it easier to grab finger foods!
Drawbacks: If you have arthritis or a weak grip, you may find the closing mechanism a bit tricky. One tip – wet the grooves first; the slider will move easier.
Also, some users mention how the bags dry too slow when hand-washed. This drying rack solves the issue. It’s not necessary, but it is helpful.
Altogether, these are healthy and versatile items that will cut a ton of plastic from your home. Plus, Homelux provides a lifetime warranty.
Cramped cabinets? These non-toxic food storage containers can DOUBLE your cabinet space!
Collapse-it uses soft, food-grade silicone to craft their containers and lids. So, zero plastic concerns.
You get four versatile containers: A round 6-cup, 4-cup, 2-cup, and 1-cup – all with 100% silicone lids, unlike most competitors.
You can pull these from the fridge or freezer, then immediately heat food in the microwave or oven up to 350℉ (176.6℃)… Without concern. Silicone Tupperware will not crack, leach, or melt.
Plus, steam vents allow you to heat food with the tops on, splatter-free.
And the easy-closing lids create an airtight, leak-proof seal, great for on-the-go.
But the best part is their collapsible feature, hence the name. Here’s how it works:
Simply press down, and the empty container collapses to 50% its original size! Then, stack them on top of each other. You’ll clear up nearly 2x more space in the same amount of cabinet.
Also, I’ve noticed you can partially collapse the container as you eat the food inside, reducing fridge clutter. This feature is beneficial for small refrigerators, like in RVs.
And keep in mind, although collapsible, they’re sturdy and shouldn’t collapse unexpectedly.
Drawbacks: The darker-colored containers seem to show hard water spots from washing. Yet, it doesn’t affect performance at all.
Overall, these are some of the best silicone food storage containers out there… For saving space and cutting toxins, at least.
Best Non-Toxic Ceramic Storage Containers
You might recognize Le Creuset from our guide on non-stick pans without Teflon.
Like their cookware, Le Creuset crafts its non-toxic food storage containers with 97 years of experience. And these versatile stoneware canisters show it.
They’re microwave, freezer, refrigerator, dishwasher, oven, and even broiler-safe.
Plus, the tough enamel resists scratching, stains, odor, and moisture/ flavor absorption.
In other words, these containers protect food flavor and lock in aroma. So, they’re perfect for storing fresh-ground coffee, nuts, oats, sugar, and other dry foods.
The container pictured measures 4″ wide x 5″ tall (10.1 x 12.7cm) and holds 22oz.
The tight-sealing beechwood lids and silicone gaskets further lock in freshness. After weeks, sometimes even months, dry goods stay like-new.
Plus, the stackable flat lids preserve countertop and cabinet space when storing.
To wash, the (almost) non-stick enameled surface wipes clean in seconds. It’s dishwasher-safe, too – minus the lids.
Drawbacks: The canister can crack if dropped, so be careful. Also, the wooden lids are not microwave-safe. Intense heat and moisture from reheating food can break the tops.
While pricey, you get your money’s worth with Le Creuset. I’ve yet to see a competitor offer the same 10-year warranty.
Want more options? Le Creuset offers five different sizes and several colors for more personalization—
If you’d like to buy elsewhere, you can explore Etsy here for more Le Creuset storage options.
This next ceramic food container mirrors Le Creuset… But at a more affordable price point – without sacrificing much quality.
It’s perfect for storing coffee, jam, rice, sugar, flour, spices, biscuits, and more. Plus, the bamboo lids with silicone sealing ring form an airtight seal. So, food stays fresh longer!
These jars come in three different sizes:
Drawbacks: Like the wooden Le Creuset lids, use caution when heating food to avoid damaging the tops.
Altogether, Le Creuset is the better option.
But these ceramic jars give you similar results at a fraction of the cost. Plus, this brand covers you with a 6-month warranty.
Side note: If you want to label these containers by contents, you can get these cool markable decals.
I’m sure we can agree that plastic wrap is bad for the environment. Yet, most cling wrap alternatives are beeswax wraps.
And here’s the thing… Most people I talk to dislike the idea of replacing plastic with animal byproducts.
So, that’s where Bees Wrap’s plant-based alternative comes in.
Their reusable food wraps consist of organic cotton and plant-based waxes only.
The idea is simple – use them for anything you’d use Saran wrap for. Wrap fruit, cheese, bread, leftovers, snacks on the go, and much more.
Also, unlike most other brands I’ve tried, these keep their shapes instead of clumping up. The wax adheres to itself better, too.
Here’s how to use them:
First, roll the wrap around in your hands. Your body’s warmth will soften the wax, making the wraps more flexible.
Then, wrap your food or cover a bowl. As the wrap cools, it’ll adhere to itself or the bowl, creating a tight seal and preserving fresh food. Naturally.
Afterward, rinse by hand with cool water and mild soap, then let air dry. You can reuse your wraps for several months!
Each 3-pack includes: One small wrap – 7″ x 8″ (17.7 x 20.3cm). One medium – 10″ x 11″ (25.4 x 27.9cm). And one large – 13″ x 14″ (33 x 35.5cm).
Best of all, Bee’s Wrap—a certified B-Corp—handcrafts their wraps in the USA! They’re Green-America Certified, too, due to responsible sourcing, manufacturing, and worker treatment.
You can feel good supporting this brand.
To wrap up, I want to say – don’t stress too much. I know this all sounds like a chore…
So, here’s the bottom line—
Don’t feel you must tear apart and rebuild your entire kitchen tonight. Continue using whatever containers you own, especially if they’re new.
Just keep in mind, there are healthy food storage containers available for when you can buy new.
So, phase out that old, questionable Tupperware over time. Replace it with the non-toxic Tupperware above!
P.S. Sustainable food storage, check. But how about the rest of your kitchen?
