Advantages of using aluminum foil containers as lunch boxes. Aluminum foil is made of raw aluminum alloy and rolled through multiple processes. It does not contain harmful substances such as heavy metals. In the production process of aluminum foil, a high-temperature annealing and sterilization process is used, so aluminum foil can be safely in contact with food and will not accommodate or help bacteria grow. In most cases, aluminum foil does not react with food. A considerable number of plastic lunch boxes on the market are made of raw materials of unknown origin or even fake materials and waste plastics, and the quality reliability is difficult to guarantee.
Aluminum foil has high conductivity, which can minimize the time and energy associated with food processing, refrigeration and secondary heating. Aluminum foil has good thermal stability. During processing and packaging, aluminum foil containers can withstand temperature changes well. At high and low temperatures of -20℃-250℃, the molecular structure is stable and unchanged. Its use temperature can range from rapid freezing to extreme baking and grilling. During this period, aluminum foil will not deform, crack, melt or burn, and will not produce harmful substances. Using aluminum foil to isolate high-temperature charcoal fire and smoke can avoid carcinogens caused by burning food. Aluminum foil lunch boxes and containers are very suitable for high-temperature sterilization and heat sealing. Aluminum foil lunch box containers can be heated in a variety of ways, including heating food wrapped in aluminum foil in various ovens, ovens, oxygen-free heating cabinets, steamers, steamers, microwave ovens (must be used in light waves and barbecue stalls), and pressure cookers. Relevant companies have developed matching aluminum foil lunch box secondary heating equipment and packaging equipment, which can greatly improve the distribution efficiency of catering companies and ensure the quality of catering. In contrast, the high temperature resistance of plastic lunch boxes and containers is significantly lower than that of aluminum foil products. After contact with high-temperature food, water or high-temperature heating, harmful substances will be released, affecting human health. (Foam lunch boxes are made of polystyrene raw materials. The softening point of polystyrene raw materials is between 87℃-97℃. Therefore, it cannot be used in a temperature environment above 80℃.
