My Top 11 Picks for the Safest Food Storage Containers


The safest food storage containers are designed to store food in a way that minimizes the risk of contamination, preserves the quality and freshness of the food, and does not transfer harmful chemicals or substances into the food.

Switching to non-toxic food containers is crucial to avoid harmful chemicals like BPA, BPS, and phthalates commonly found in plastic containers, which can disrupt hormonal functions and may leach into food.

Safer options include:

  • High-density polyethylene (HDPE) and low-density polyethylene (LDPE): These plastics are chemically inert, BPA-free, and provide a moisture barrier. They are cost-effective, lightweight, and recyclable.
  • Silicone: Durable and heat-resistant containers won't leach chemicals into food, making them a safer alternative to traditional plastic.
  • Glass: Inert and impermeable, glass preserves food flavors and nutritional content. It's fully recyclable and eco-friendly.
  • Stainless Steel: Non-reactive stainless steel maintains food taste and quality. It's durable, easy to clean, and recyclable.
  • Beeswax Wraps: These natural wraps create a reusable seal without chemicals.
  • Organic Cotton: Cotton storage options are safe and environmentally friendly.

When choosing safe food storage containers, consider these key factors:

  • Seal Quality: Opt for containers with airtight seals to prevent food spoilage, minimizing waste and emissions.
  • Size & Stackability: Select containers that fit your kitchen space and are easy to store, preventing clutter.
  • Microwave/Dishwasher Compatibility: Ensure the product suits your lifestyle and appliances.

A final word on the safest food storage containers

Reusing what you already have around the home - especially items that might have otherwise gone to waste - is a great sustainable solution!

For example, I sometimes reuse organic cotton and make a DIY fabric sandwich bag when I am zero waste camping to store/transport food. You can also reuse mason jars; these are especially handy when transporting/shopping for food in bulk.

So, what are the safest food storage containers to hold your sustainable snacks? 

You want to look for durable containers that are BPA/BPS free, nontoxic, and made from eco-friendly materials. Reusing products you already have (like reusing old Tupperware) is also a great way to go because you are avoiding the emissions of creating something new.
