CuBE containers are made from microwave safe materials and are suitable for reheating precooked foods. Frozen food must be defrosted before reheating. Never heat beyond 100°C/212°F (the temperature of boiling water). Some foods, such as those high in oils, fats, sugars, or salts, can reach temperatures above 100°C/212°F when heated too quickly and/or for too long. Such overheating can cause damage and potentially melt the container. Should this occur, discard both the container and its contents. Never use a CuBE container in a conventional oven, convection oven, toaster oven or on a stove top heating element. Always leave the lid open when using the microwave. Follow the manufacturer’s guidelines when using in a microwave oven and use care when handling a hot container.
