Safest Non Toxic Food Storage Containers of 2020

Non Toxic Food Storage Containers

In previous articles we’ve discussed non-toxic dinnerwarecookware, and even cleaning products 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 practicing healthy cooking habits like using non-toxic cookware and serving food on safe dinner plates only to have your food tainted with toxins by the container it’s stored in.

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.

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

Most food storage containers are made of plastic and many of these are not healthy at all.

That brings us 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 easily, and are very convenient. Sounds great except that misuse can cause damage to your health. This begs the question: what are the dangers of plastic containers for food?

Plastic food storage containers can be made from different sorts of plastic.

Some are safer than others but you never truly know, and even some that are quoted as “safe” can become dangerous when exposed to certain stressors.

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

When your plastic containers are exposed to these stressors, chemicals such as Bisphenol A (BPA) and Phthalates can leave the plastic and migrate into your food which then in turn ends up inside your body.

BPA is a chemical that’s been used to harden polycarbonate plastics and epoxy resins.

These plastics are usually 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, chemicals with EA have been linked to all kinds of health issues like negative effects on the heart, brain, and child developmental problems.

Early childhood exposure to BPA has been linked in a study to ADHD behaviors like 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 definitely 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 fully avoid plastic altogether as plastic container usage is so 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?

In order 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, but this section is for those of you who have no choice but to use plastic and simply 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 a number of 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 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.

Because BPA has been used in plastic since the 1950s, many older plastic containers are even more likely to contain the chemical because less information was available on its dangerous side effects.

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) as 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.

The bottom line, if you have to use plastic containers be sure to check it’s 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.

These containers are generally made from glass, stainless steel, silicone, or ceramic as each of these materials are 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 a 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!

Glass food storage containers are generally made from soda-lime glass which is made of 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

  • 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 amazing 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 easily be carried along on trips.

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


  • Plastic-free
  • Toxin-free

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

This revolutionary material shares the desired characteristics of plastic (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 a great option around kids.

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


  • Plastic-free
  • Toxin-free
  • Microwave safe

  • 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 clean and natural material, made from clay and other earthen elements that are 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

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 the popularity of Pyrex glass food storage containers.

This is due to the versatility of the glass and its ability to be used in the oven, microwave, fridge, and freezer.

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

The lids on these containers are also plastic so you’ll need to take care not to heat with the lids on, but overall these are generally very safe  and high-quality containers.

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

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