The science
Why food storage, but plastic free?
Storing and especially reheating food in plastic is one of the most direct ways particles end up on your plate. Glass, stainless steel, silicone, and beeswax wraps let you store, freeze, and reheat without the plastic-to-food transfer, particularly the heat-driven shedding.
Wirecutter specifically recommends avoiding storing and heating food in plastic as a way to cut microplastic intake. · NYT Wirecutter, 2024
Unwrapping and handling plastic-packaged food sheds micro- and nanoplastics directly into the food. · CNN Health, 2025
Common questions
- Is it really worse to microwave food in plastic?
- Heat dramatically increases how much plastic migrates into food, so glass or ceramic is the safer choice for reheating.
