My Humble Earth's reusable ziplock bags are made from food-grade silicone and are suitable for both extremely high and low temperatures. These ziplock bags do not contain BPA, phthalates, plastic or fillers.
What options are available?
These ziplock bags are oven, microwave, and freezer safe. They are also airtight and suitable for the storage of liquids.
They are also dishwasher safe and can be cleaned with soapy water by hand.
The sliding rod cannot be put in the oven or microwave. The ziplock bag also cannot be turned inside out, as it breaks down the seal of the silicone bonds.
