Are Preserve products microwave safe?
Our food storage products have been tested for microwave durability by a leading independent certifier and will not, break, crack, or overheat when used for reheating foods in the microwave. The plastics used to make our products also meet FDA approval for temperatures found during microwaving. However, we still believe that the decision of whether or not to microwave your food in any plastic is ultimately a personal one, since there is still debate about the health risks of doing so. While our other products have not yet undergone the certification process, they are made from the same FDA-approved plastics as our food storage containers. Over time, we will continue to test our other products through independent third party certifiers.
