Ditch ziplocs once and for all with REstash - long lasting, sturdy reusable bags. They can be used for short or long term food storage as the airtight seal preserves food freshness. Use REstash to refrigerate or freeze, marinade, microwave, sous vide, steam or boil, reheat, and even eat out of! REstash lay flat for storage but once filled will stand upright for easy use. Dishwasher safe. The silicone bag can withstand temperatures up to 230 degrees Celsius and the plastic seal can go up to 90 degrees Celsius. The bag can be boiled but not the seal. (End of life) Bring it back and we'll make sure it gets recycled properly. These bags are built to last. In our experience, after years of use they still look and work like new. But if they do reach the end: Silicone, like plastic, can be recycled multiple times. However, silicone usually has to be sent to a specialized recycling company to be properly recycled. We're building our take back program to recover these products.
