A lot of lunch boxes and bags are made out of PVC or other types of plastic that contain endocrine disrupting chemicals like BPA and phthalates, which come with potential negative health effects.

Although it’s important to avoid these types of plastic as best you can throughout the different areas of life, it’s even more crucial to do so when it comes to food storage. When it can be avoided, you don’t want to end up eating these chemicals after they leach into your food.

So in this article, we’re talking about what materials to look for in safe, non-toxic lunch boxes. Then we’ll give you our favorite brands.

What To Choose? Non-Toxic Boxes, Bags, & Bento Boxes for 2023

Before you pick out your lunch necessities, you’ll want to consider your (or your child’s) personal preferences. Do you want a sturdy lunch box that can take a beating on your morning commute, or will a soft lunch bag suffice? Do you need something you can swing around your arm or throw in another bag? Would you prefer a Bento box that you can keep your whole meal in? What size would be best for you and your eating habits?

Choosing non-toxic materials is important, but you should also get something that will fit well into your lifestyle so that you’ll actually enjoy using it! That’s why we’ve included a variety of different types of boxes and bags below.

Materials to Be Careful Of

Most of the lunch boxes, backpacks, and pencil cases you’ll find at the store are either made from a soft plastic, which often contains PVC and/or phthalates; or hard plastic, which can contain BPA or other bisphenols.

Here are why those materials are problematic:

PVC

PVC (polyvinyl chloride) is actually one of the most toxic kinds of plastic. In fact, some countries have begun banning the use of PVC, especially in food packaging.

PVC contains chlorine, which creates toxic byproducts called dioxins. According to the World Health Organization (WHO), dioxins “can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer.”

Not only that, but PVC often contains toxic additives like lead and phthalates.

Phthalates

Although phthalates are often found in PVC, they can also be in plenty of other types of plastic as well. They’re typically used to make the plastic more flexible. So when you’re shopping for lunch boxes, you’ll want to look for brands that explicitly test for all phthalates.

Phthalates are endocrine disruptors, which means they can interfere with one’s natural hormone function and lead to infertility and developmental toxicity. They’re also linked to things like diabetes and asthma, and also may be carcinogenic.

BPA & Other Bisphenols

While softer plastic lunch boxes are more likely to contain phthalates, harder plastic lunch boxes are more likely to contain BPA and other bisphenols. Like phthalates, bisphenols are also endocrine disruptors are linked to a list of health concerns.

We recently took a deep dive into BPA and it’s “sister chemicals” like BPS and BPA, so you can read more about that here.

Water/Stain-Resistant PFAS Chemicals

It’s reasonable to want your lunch box to be resistant to water and stains since you might have to deal with spills and you definitely don’t want to end up with a moldy lunch bag.

But a lot of lunch boxes are treated with a DWR (durable water repellant) finish to make them waterproof, which you do NOT want.

PFAS have been nicknamed “forever chemicals” because they can’t be broken down by our bodies or the environment. They are known toxins and are linked to a wide variety of serious health concerns, including cancer, reproductive and developmental problems, metabolic dysfunction, immune dysfunction, and more. You don’t want this stuff around your food if you can avoid it!

Most synthetic fabrics are inherently water-resistant and relatively easy to clean, and most natural fabrics like organic cotton or linen can be put into the washing machine. Therefore there’s really no reason for these toxicants to be added to our lunch bags. If you want to add a natural and non-toxic water-resistant finish to your lunch bag, you can use this wax bar from Rawganique.

Safer Lunch Box/Bag Materials to Look for Instead

Organic Cotton

Lunch bags made from organic cotton or other natural materials such as hemp is a great choice (as long as they don’t have any PFAS added on top!). Not only are harmful pesticides not used in the growing or processing of these materials, but you also don’t have to worry about the hidden ingredients that often come with plastics, as mentioned above.

Since these materials are not stain-resistant and can’t be wiped clean as easily as plastic can, they may be more susceptible to getting dirty. But the good thing is that most of the time, they’re machine washable! (Just make sure to follow the directions because some of them aren’t meant to go in the dryer.)

Be careful about any lunch bags made from natural fabrics that say they’re stain- or water-resistant/proof. This indicates there may be a toxic layer of PFAS chemicals on top of the fabric.

Stainless Steel

Stainless steel is a safe food storage material that many people use for soups, sides, and snacks. It’s super durable and can keep your foods hot or cold (with the proper sealing).

Depending on your preferences, you may use a stainless steel storage container within your larger lunch box or bag, or you may use a Bento box (like this one, which can hold your entire lunch) all on its own.

Silicone

Silicone is a plastic-adjacent material that is much safer than real plastic. A lot of people like to use silicone in place of plastic for things like container lids and baggies (like the now-famous Stasher bags!). They’re definitely a great option for kids because they are lightweight, flexible, and won’t break if they’re dropped. Depending on the specific product, they may or may not be able to hold liquids.

High-quality, food-safe silicone is generally safe at room temp and frozen.

Although it’s probably fine for warm foods, it may not be great at very high temperatures. Although we need more data, some research suggests that certain kinds of silicone may release endocrine disrupting chemicals at high temperatures (like in the oven).

Safer Plastics

Sometimes (especially when it comes to kids), plastic is just easier. It’s easier to wipe clean and can be more leak-proof, waterproof, and mold-resistant compared to something like organic cotton. And you’re just not likely to find an entire lunch box/bag that’s made from all-silicone.

So if you’re going to go with plastic, some choices are much better than others. In general, plastic product with the resin codes #2, #4, and #5 are the safest.

Polyester, although not perfect, is generally better than something like PVC. Polyester can also be more resistant to things like water, stains, and mold compared to certain natural fibers like cotton.

Additionally, look for brands that use third-party testing to make sure their materials don’t contain phthalates, lead, bisphenols, or other toxicants.

Remember to keep all types of plastic away from the heat whenever possible, though. Heat speeds up the leaching process.

Food-Grade Everything

Regardless of which materials you choose for your lunch necessities, make sure that the material that’s actually next to your food is labeled as food-grade. Food grade materials have stricter manufacturing requirements and have to meet certain FDA requirements.

(BUT, just because something is food-safe does NOT automatically mean it’s free from things like phthalates and BPA, and there is very little actual oversight on this issue. A food-grade label is not an end-all, be-all; it’s just another helpful thing to look for.)

Here Are Our Favorite Non-Toxic & Organic Lunch Boxes & Bags (for the Whole Family)

Alright, now on to our favorite non-toxic lunch box brands!

1. Fluf (Best for Organic Cotton Lunch Bags)

Types: Lunch bags, sandwich & snack bags, backpacks
Best for: Adults, kids, & toddlers
Materials: Organic cotton + RPET lining
Price: $8.95 (snack bag) – $31.95 (lunch bag)

Fluf is one our favorite brands for safe and fun lunch bags & other essentials, as well as backpacks. Some of their designs are minimalistic and elevated (which are great for adults), while other designs are fun and colorful (great for kids).

They also have sandwich bags and snack bags that come in a variety of sizes. Some have Velcro and some are zippered. And they’re all fully machine washable!

They use GOTS certified organic cotton and low-impact dyes for the outer fabric. For the lining, they use eco-friendly GRS-certified (Global Recycle Standard) rPET, which meets the STANDARD 100 by OEKO-TEX® for safety. This makes the lining more water-resistant without any toxic PFAS being added to it.

Their products are regularly tested by third party labs to be free of things like BPA, PVC, PFAS, phthalates, heavy metals, AZO, fire retardants, formaldehyde, and more.

In addition to their strict safety standards, Fluf also has other sustainable and ethical initiatives as well. Everything is ethically made in India where workers are paid a living wage and work under safe conditions.

Their team works to reduce plastic as much as possible throughout their entire supply chain, from the product design process to packaging.


2. ECOlunchbox (Best for Stainless Steel Lunch Boxes & Bento Boxes)

Types: Lunch bags, Bento boxes, stainless lunch containers
Best for: Kids & adults
Materials: Organic cotton, stainless steel, silicone
Price: $10 (food storage container) – $50 (giant stainless steel lunch box)

ECOlunchbox is a great option because they have a little of everything: lunch bags, food storage containers, stainless steel bento boxes, and even camping plates and little sporks! Their entire line of products is almost completely plastic-free.

Their machine-washable lunch bags are made out for GOTS certified organic cotton and screen-printed with cute sea animals using eco-friendly ink. Some of their food storage containers & bento boxes are 100% food-grade stainless steel, while others include food-safe silicone lids and/or gaskets.

They offer storage containers that come in various shapes and sizes (circular vs. rectangular; snap-shut vs. regular lids; etc.), and many of their containers are leak-proof.

ECOlunchbox is also a B Corp certified brand that has various sustainable and ethical initiatives in place throughout their entire supply chain.


3. Etsy (For Plastic-Free, Non-Toxic Lunch Bags of Various Kinds)

Types: Lunch bags, wraps, and snack bags
Best for: Adults & kids
Materials: Organic cotton, linen, wool, natural wax

They also carry other lunch essentials like smaller organic cotton snack bags, beeswax wraps, and more. Materials and quality vary widely on Etsy, so just make sure you check the product description before buying, and don’t hesitate to message the seller to ask more questions if you need to.

Types: Child’s lunch box & backpack options
Best for: Kids & toddlers
Materials: Organic cotton + RPET lining
Price: $8.95 (snack bag) – $31.95 (lunch bag)

Even though they’re made from plastic, they are lab tested to be free of toxins like PVC, BPA, phthalates, and lead. The interior lining is made out of PEVA, which is a safer and more eco-friendly alternative to PVC. This makes the lunch box more resistant to spills without having to add any toxins like PFAS to the fabric, which is an important consideration for the messier members of the family!

Bixbee is also a Certified B Corp brand that donates school bags and other supplies to non-profit organizations with each purchase. In addition to lunch boxes, they also carry other school essentials like backpacks, pencil cases, and duffle bags.


5. Austin Baby Collection (Best for Leak-proof Silicone Bento Boxes)

Types: 5-section silicone Bento boxes
Best for: Toddlers, kids, teens, and adults
Materials: Food-grade silicone
Price: $29

Technically, these silicone Bento boxes are targeted towards parents of toddlers and young kids, but they can totally be used by adults, too! Some of them have cute, kid-friendly designs on the lid, but they also have more mature options and solid colors, too.

Not only are these lunch containers made out of 100% food-grade silicone, but each section comes with its own leak-proof, individually sealable compartments! So this is a great option for even more liquid-y things like yogurt or hummus.


6. The Dearest Grey (More Silicone Bento Boxes)

Types: 3-section Bento boxes and 1-section mini Bentos
Best for: Adults & kids
Materials: Food-grade silicone
Price: $18-25

Much like the Austin Baby Collection, these silicone Bentos are marketed toward little ones, but can definitely be used by teens and adults. They come in a variety of colors, including solids and tie-dyes.

Many of their options include three sections, but their 1-section “minis” are great for packing snacks.

They’re made from 100% food-grade silicone and are top-rack dishwasher safe, freezer safe, and microwave-safe.

Be aware that The Dearest Grey does not accept returns, so make sure you know what you’re getting!

For collapsible silicone food storage containers, check out Stojo. The bowl part of the containers are made out of 100% food-grade silicone, but be aware that the lids are made of plastic.


7. Milkdot (Lab Tested Lead-Free & Phthalate-Free)

Types: Insulated lunch bags and backpacks
Best for: Adults & kids
Materials: 600 denier polyester
Price: $27

Milkdot’s lead-safe lunch bags are made from polyester, but they’re free from PVC, phthalates, lead, and BPA (and tested by a third-party lab).

They come in various colors and patterns and can be a good fit for both grade-school kids and adults. (They even have a little picture frame ID tag for personalization or secret lunch notes, which is a cute extra feature.)

They do use foam insulation, which isn’t great… but at least that part is not touching your food.


PlanetBox (PFAS-Free Lunch Boxes)

Types: Recycled lunch boxes, stainless steel Bento boxes and food storage containers, water bottles, and accessories
Best for: Kids
Materials: Outer material is 100% recycled PET. Inner material is 100% polyester. Fill material is polyethylene foam.

Even though PlanetBox’s lunch bags and totes are not made from natural materials (they’re mostly polyester), they are now free from DWR/PFAS treatments.

Additionally, many of their food storage containers are made from stainless steel that’s free from toxicants like bisphenols or phthalates.


More Non-Toxic Lunch Gear

Here are some more products for non-toxic lunch gear:

1. Baggies & Other Storage Necessities

What you choose to store your food in is important. Since endocrine disruptors can leach from the plastic to your food, choosing a non-toxic and plastic-free food storage option is an easy thing you can do that can potentially make a big difference.

We actually have an entire article that’s all about non-toxic food storage, which you can check out here.

To summarize our recommendations specifically for packed lunches:

  • Made from silicone, Stasher Bags are perfect for reusable snack bags that can be thrown in backpacks, lunch totes, or purses. They have a wide variety of options so you can find something that’s just the right size for what you need. (Check out this article for more plastic-free Ziploc alternatives.)
  • Although glass food containers are a great option, they’re very breakable and many schools don’t allow them in the cafeteria. We recommend stainless steel containers, like those from ECOlunchbox or UKonserve.
  • Beeswax Wraps are a great alternative to plastic cling wrap and a a great lightweight way of wrapping up sandwiches, fruit, and more.

2. Ice Packs

Here a a few non-toxic (or low-tox) options for ice packs that you can throw in your lunchbox and keep things cool:

  • Onyx (water inside; stainless steel outside)
  • UKonserve (non-toxic sodium polymer inner with a recycled plastic cover)
  • SoYoung (water/cellulose gum inner with polyester cover)

3. Utensils

For forks and spoons, you’ll want to skip the plastic and go with:

  • Bamboo (like To-Go Ware)
  • Silicone (like ezpz, for kids)
  • Or just use the regular stainless steel flatware from your kitchen!

4. Napkins

The best options for napkins are:

5. Water Bottles

We have an entire guide to non-toxic water bottles in the queue, too, so stay tuned for that! In the meantime, here are some of the brands we recommend:

What About These Lunch Bag Brands?

Here are some more brands you may be wondering about that didn’t make the list at this time:

Calpak: We don’t recommend this brand. Among other types of plastic, it uses polyethylene, which may leach endocrine disruptors. Some of their bags also come with Prop 65 warning labels, which can mean they contain lead or a variety of other toxicants.

Corkcicle: While their stainless steel bottles and cups are probably fine, we don’t recommend their lunch boxes or other bags. It’s unclear what they’re actually made of and whether or not they’ve been tested for endocrine disruptors or other toxins.

Hydroflask: They say their lunch boxes and bags are BPA & phthalate-free, but it’s unclear what they’re actually made out of (and whether they contain any other bisphenols or endocrine disruptors). Their stainless steel bottles, cups, and jars are a good option, though!

L.L. Bean: Their lunch boxes are probably okay… They say they’re tested safe for lead, phthalates, PVC, and BPA. However, it’s unclear what kind of plastic they’re actually made out of and whether or not they’re free from all bisphenols and endocrine disruptors.

Modern Picnic: This is a brand that offers aesthetically-forward lunch bags for professionals. Unfortunately, they lack transparency, though. Their bags are made from vegan leather (which is most likely plastic, but they don’t tell us what kind) and they don’t say anything about bisphenols, phthalates, testing, etc.

State: They told us that their bags are not PFAS-free.

(If there are any other brands you’re wondering about, just let us know in the comments below and we’ll look into it!)

So, Which Lunch Box Is Best For You?

By choosing from the non-toxic options listed above, you don’t have to pack yours or your kids’ school lunches with toxic chemicals like PVC, phthalates, BPA, or PFAS!

Even More FAQs About Non-Toxic Lunch Boxes

Are bamboo lunch boxes toxic?

Bamboo can be a good plastic-free option for lunch boxes, but be aware that bamboo tends to be more prone to mold, especially compared to other plastic-free alternatives such as silicone and stainless steel.

Are silicone lunch boxes safe?

Yes, silicone lunch boxes can be a great BPA-free alternative to plastic food storage containers. Like plastic, they are lightweight, shatter-resistant, and easy to clean. Just make sure you look for 100% food-grade silicone in order to avoid plastic fillers.

Do Bento boxes have phthalates?

Bento is not a material, but rather a style of lunch food container. So whether or not your Bento box contains phthalates depends on what it’s made out of. To avoid phthalates in Bento boxes, choose a plastic-free food storage container that’s made out of healthier materials such as food-grade silicone or stainless steel.

Are stainless steel lunch boxes safe?

Yes, stainless steel is generally a safe, non-toxic alternative to plastic lunch food containers.

    1. Hi there, I actually reached out to Bentgo because I couldn’t find the info on their website and they told me that their bags DO have a PFAS coating on the outside. So unfortunately, I can’t recommend them at this time, πŸ™

  1. So I have found the lunch bags I got for my daughter do not fit any of her lunchbox bentos. In this article it says that most of Planetbix bags have PFAS. What about the ones that do not? The Rover/launch bags state there are not any DWR treatments on them. Would this make a good option for a lunchbox? Or would you have another suggestion that would fit the Planetbox rover? Thank you!

    1. Hi Niece,
      I have been in contact with PlanetBox and they have informed me that all of their bags are free from DWR/PFAS treatments now. I’ve updated the post accordingly and would say that they are a pretty good option!

  2. I am looking for a plastic-free thermos for kids lunch boxes. The Ukonserve 18 oz is too big–I am looking for something closer to 8-12 oz. I know they make a 12 oz. version but it has a plastic lid

    1. This is a tough one! Most of the ones I’ve found are too big.
      It looks like Klean Kanteen has one, but it’s not clear what the lid lining is made of (could be plastic or silicone). https://www.kleankanteen.com/collections/insulated-food-containers/products/insulated-food-container-8oz … It also doesn’t have great reviews. πŸ™
      Stanley and Thermos also have some options, but they all have plastic lids.
      I will keep my eye out, but I would suggest just going with the plastic-lid one for now… Even though it’s not ideal, it’s still a lot better than a totally-plastic container!
