Aluminum foil has a high conductivity, can minimize the time and energy related to food processing, refrigeration and secondary heating. Aluminum foil has a good thermal stability. In the process of processing and packaging, aluminum foil containers can well withstand the temperature change. Under the high and low temperature of -20�°C -- 250�°C, the molecular structure remains stable. It can be baked and barbecued at temperatures ranging from quick-freeze to extreme, during which the foil does not deform, break, melt or scorch, or produce harmful substances. Use aluminum foil to separate the hot coals from the smoke, which can prevent food from burning and causing carcinogens. Aluminum foil food trays and containers are ideal for high temperature sterilization and heat sealing.
