7 Non-Plastic, Heat-Safe Food Storage Containers at Amazon

Microwaving plastic food containers for just three minutes can release up to 4.22 million microplastics and 2.11 billion nanoplastics per square centimeter, according to a 2023 study in Environmental Science & Technology. That’s millions of invisible particles seeping into your leftovers, soups, and sauces every time you go to reheat them. Even outside your microwave, microplastics and forever chemicals are reportedly leaching from kitchen essentials like plastic cutting boards and nonstick pans, so this might be the right time to ditch plastic once and for all.

Looking for smart, non-toxic food storage containers to get instead? Amazon has a wide selection of silicone and glass food storage options, including the Pyrex containers an editor’s mom can’t get enough of and a big meal prep set that costs less than $3 apiece.  Stop reheating your food in those plastic takeout containers — switch to these heat-safe alternatives, which not only make mealtime a little bit healthier, but will declutter your refrigerator, too.
