Guides › Food Storage
Most “leak-proof” storage is plastic, and it's the plastic your leftovers get microwaved in. Glass with a real seal and stainless tins do the same job without the plastic touching hot food.
What to look out for: Borosilicate glass or 18/8 stainless; watch that lids aren't the plastic you're trying to avoid.
Quick answer: Our top pick for plastic-free food storage is the Le Parfait Super Jars (Set) ($50.00). Best on a budget: the Stasher Reusable Silicone Sandwich Bag ($11.19). Most-reviewed: the Anchor Hocking Heritage Hill 1 Gallon Glass Jar with Glass Lid (Set of 2) (11,197 reviews).

The container is; the lid isn't. Warm, fatty leftovers pressed against a plastic lid is exactly the contact you're trying to avoid, so we check and name the lid material on every pick.
Most glass storage handles the microwave, oven, and freezer — just avoid sudden temperature jumps, like freezer straight to a hot oven. Whatever you do, don't microwave food in plastic: heat is when plastic leaches most.
We treat food-grade silicone as acceptable: it's more heat-stable than common plastics like polyethylene, though research on what it releases over time is still limited. It's also not a natural material, so we name it wherever it appears.
