How to Swap to Non-Toxic food storage bags:

Here's how to swap to non-toxic food storage bags:

What to know about food storage bags

Food storage bags come into direct contact with the food you and your family eat, often for hours or days at a time. Welpr looks at what these bags are made of, including the type of material, any chemical treatments, and whether the materials can transfer into food — especially with heat, acidity, or prolonged storage.

  • Bags used for hot foods, fatty foods, or long-term freezer storage deserve the most attention since these conditions can increase what transfers into food.
  • If you use food storage bags daily — for lunches, snacks, or meal prep — they are a higher priority to evaluate than bags you rarely reach for.

Review the bags you already use

Check the packaging or product description of your current food storage bags. Look for information about the type of material, whether they are labeled BPA-free, and if there are any claims about chemical treatments or additives.

  • Look on the box or bag for recycling codes — common food storage bags are made from polyethylene (recycling codes #2 or #4), which is generally considered a simpler, more straightforward plastic.
  • Start by reviewing the bags you use most often or the ones that come in contact with warm or fatty foods.

Use your current bags more carefully

If you are not ready to replace your bags right away, small changes in how you use them can reduce what transfers into your food. Avoiding heat exposure is one of the most effective steps you can take.

  • Let hot food cool down before placing it in a plastic bag, and never microwave or heat food directly in a storage bag.
  • For acidic or fatty foods like tomato sauce or cheese, consider placing a piece of parchment paper between the food and the bag as a simple barrier.

Choose cleaner replacements

When it is time to replace your food storage bags, look for options made from simpler materials without added chemical treatments, synthetic fragrances, or unnecessary coatings. Reusable bags made from food-grade silicone or uncoated natural materials are worth considering.

  • Look for bags that are free of BPA, BPS, PVC, and phthalates — and be cautious of vague claims like "eco-friendly" without specifics about what the bag is actually made of.
