Borosilicate glass is chemically inert — no microplastics leach into food, even when heated in the microwave or dishwasher.

Organic cotton coated in beeswax and tree resin replaces plastic cling wrap entirely. Compostable after about a year of regular use.

Plastic cling film sits directly on your food, often for hours, shedding microplastics — especially into fatty or acidic foods. These wraps swap that out for organic cotton infused with beeswax, jojoba oil and tree resin. Every material touching your food is natural.
What this is made of: organic cotton, beeswax, jojoba oil and tree resin — no plastic film. Compostable at the end of its life.
Plastic cling wrap (PVC or LDPE) is one of the most direct sources of microplastic contamination in your kitchen. It sits directly on your food — often for hours or days.
Microplastics shed from plastic wrap can transfer directly to food, especially fatty or acidic foods. Heat, time, and food chemistry all increase the rate of microplastic migration from plastic wrap into what your family eats.
Straight answer: we're a research team, not a testing lab. Here's exactly what our rating is based on — and what it isn't — so you can weigh it honestly.
Anything that adds a known microplastic, PFAS, or off-gassing source — a non-stick coating, a plastic surface against food or skin, vinyl/PVC — is downgraded or cut. We only list what clears that bar.
Borosilicate glass is chemically inert — no microplastics leach into food, even when heated in the microwave or dishwasher.
Hard maple is naturally antimicrobial and sheds zero plastic particles. Research shows plastic boards release up to 79 million microplastics per year.
Zero coating to degrade — naturally nonstick when seasoned. Unlike Teflon pans, cast iron releases no PFAS or microplastics, even at high heat.
