Reusable Silicone Bag
Platinum silicone bag that replaces single-use plastic zip bags - it's silicone, not plastic-free, but it's the durable reusable answer to Ziplocs.
Plastic-free verdict: Silicone only
Made entirely of platinum food-grade silicone with a pinch-lock seal. It is silicone, not a plastic - free of BPA, BPS, phthalates, and latex - but silicone is a synthetic material, so this is a silicone-only product, not a plastic-free one. Its value is displacing disposable plastic bags.

The reusable silicone bag that popularized the category. Freezer-, microwave-, dishwasher-, and sous-vide-safe, it replaces disposable zip-top plastic bags with something you keep for years. We list it honestly: it is not plastic-free (silicone is synthetic), but for the specific job of replacing single-use plastic bags it is the durable, non-plastic option. Strict avoiders who reject silicone should use jars or steel tins instead.

- Very durable; freezer to boiling water to dishwasher
