More non-toxic lunch gear
Beyond boxes and bags, consider these safer accessories for packed lunches.
1. Baggies & other storage necessities
Choose storage that won’t leach endocrine disruptors into food. Silicone bags are a great reusable option. For breakable items, stainless steel containers are durable alternatives to glass when needed. Beeswax wraps also replace single-use cling wrap.
2. Ice packs
Stainless steel ice packs filled with distilled water are plastic-free cooling options for lunch totes.
3. Utensils
Avoid single-use plastic cutlery. Use bamboo utensils, silicone kids’ utensils, or regular stainless steel flatware from home.
4. Napkins
Opt for reusable organic cotton, hemp, or linen napkins. Unbleached paper towels are another low-tox single-use option.
5. Water bottles
Choose stainless steel or glass bottles with protective sleeves. Brands that use food-grade stainless steel and medical-grade silicone components reduce the risk of chemical exposure from drinkware.
What to choose? Lunch boxes, bento boxes, lunch bags—oh, my!
Consider lifestyle and preferences first: do you need a rigid box for protection, a soft bag to toss into a larger tote, or a bento-style container with compartments? Pick a material that matches your needs and is safe where it contacts food. A product you actually use regularly is better than a perfectly “safe” item that stays unused.
Materials to be careful of
Many common lunch items use soft plastics (often containing PVC and phthalates) or hard plastics that can include BPA or other bisphenols. Watch for these problem materials:
PVC
PVC (polyvinyl chloride) can contain chlorine and toxic additives like lead and phthalates. Dioxins, a harmful byproduct associated with PVC production and disposal, are linked to reproductive, immune, and developmental harm.
Phthalates
Phthalates are used to soften plastics and are endocrine disruptors associated with reproductive and developmental effects, metabolic issues, and other health concerns. Look for brands that test explicitly for phthalates.
BPA & other bisphenols
BPA and related bisphenols (like BPS/BPF) are endocrine-disrupting chemicals often found in hard plastics. “BPA-free” labels are not always sufficient—brands that perform thorough third-party testing are preferable.
Water/stain-resistant PFAS chemicals
PFAS (per- and polyfluoroalkyl substances) are often applied to fabrics to add water or stain resistance. These “forever chemicals” persist in the environment and are linked to cancer, immune and metabolic dysfunction, and reproductive harms. Prefer products that avoid PFAS treatments, or use natural waterproofing alternatives such as waxed canvas or beeswax-based products.
Safer lunch box/bag materials to look for instead
Cotton or organic cotton
Lunch bags made from organic cotton, hemp, or linen are good choices when they don’t carry PFAS finishes. They’re often machine-washable and avoid synthetic additives used in plastics.
Stainless steel
Food-grade stainless steel is durable, non-reactive, and a safe option for containers that hold soups, sides, and main dishes. Use stainless containers within a larger bag or choose a stainless bento box for an all-in-one solution.
Silicone
Food-grade silicone is a safer alternative to petroleum-based plastics for lids, containers, and reusable bags. High-quality, platinum-cured silicone is stable at room and cold temperatures and is commonly dishwasher-safe. Avoid exposing silicone to very high temperatures where degradation could occur.
Safer plastics
If you need plastics for durability or ease of cleaning, choose products made from resins that are generally safer (commonly noted as #2, #4, or #5) and from brands that do third-party testing for phthalates, bisphenols, and heavy metals. Keep plastics away from heat to reduce leaching.
Food-grade everything
Ensure any material in direct contact with food is labeled food-grade. This indicates stricter manufacturing standards, though it does not guarantee absence of all concerning chemicals—look for transparent, third-party testing when possible.
Brands that didn’t make the cut
Some familiar brands were excluded due to lack of transparency or materials that raise concerns. Examples include items from brands using unclear plastic formulations, products flagged with Prop 65 warnings, or companies that explicitly state their items are not PFAS-free. When considering any brand, check materials, testing, and labeling before you buy.
Choosing safer lunch gear—like stainless steel containers, food-grade silicone, and organic cotton bags—reduces the chance that PVC, phthalates, BPA, or PFAS will touch your food. Pick functional items you’ll use daily and prioritize clear materials descriptions and third-party testing when possible.
