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 actually look for: Borosilicate glass or 18/8 stainless; watch that lids aren't the plastic you're trying to avoid.
