Brand Rating
Stasher
Platinum silicone reusable bags — the most popular alternative to single-use Ziploc bags. B Corp, plastic-free, PFAS-free, dishwasher/microwave/oven safe. Made in China (the silicone supply chain is hard to localise). The real downside is price: $13-25 per bag makes the upfront cost high compared to a box of Ziplocs. However, they last for years.
