As a packaging material, aluminum foil is first used in the field of pharmaceutical packaging, and secondly, it is more common in the field of high-end food packaging. The reason why aluminum foil can be qualified for packaging tasks in these high-end fields is due to its following advantages:

1. Aluminum foil lunch box has high barrier performance. Aluminum foil has high barrier properties to water, water vapor, various gases (including aromatic substances) and light, and the barrier performance is not affected by ambient temperature and humidity. It can be used for air-tight, fragrance-preserving packaging, moisture-proof packaging, etc. requiring high barrier properties Packaging occasions (especially food packaging for high-temperature retort sterilization) can prevent moisture absorption, oxidation and volatilization of the contents. Therefore, aluminum foil can be safely in contact with food, and will not contain or help bacteria grow. In most cases, aluminum foil will not react with food. However, a considerable number of plastic lunch boxes on the market are produced with raw materials from unknown sources, even fake materials, and waste plastics, and the quality and reliability of them is difficult to guarantee. If calcium carbonate, talcum powder, industrial paraffin, and recycled waste are added to disposable plastic tableware, it is easy to cause the evaporation residue (n-hexane) of the product to exceed the standard.


Second, it has good thermal conductivity, heat resistance and low temperature resistance. Aluminum foil can withstand high-temperature cooking and other thermal processing, has good thermal conductivity (the thermal conductivity can reach 55%), and does not produce harmful substances after heating; at the same time, aluminum foil is also suitable for freezing packaging, and has good low temperature resistance. It can maintain a stable shape and size at low temperatures. Aluminum foil can greatly reduce the time and energy associated with food processing, cold storage and secondary heating. The thermal stability of aluminum foil enables the aluminum foil container to withstand temperature changes well during processing and packaging. The molecular structure is stable and does not change under high and low temperatures of -20°C to 250°C. Its use temperature can range from rapid freezing to extreme baking and grilling. During this period, the aluminum foil does not deform, crack, melt or burn, and will not produce harmful substances.

Use aluminum foil lunch boxes to separate high-temperature charcoal fires and smoke to avoid carcinogens caused by food scorching. 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 various ovens, ovens, anaerobic heating cabinets, steamers, steamers, microwave ovens (must be used in light waves and grilling), pressure cookers to heat foods wrapped in aluminum foil. Related companies have developed supporting secondary heating equipment and packaging equipment for aluminum foil lunch boxes, which can greatly improve the delivery efficiency of catering companies and ensure the quality of meals. In contrast, the high temperature resistance of plastic lunch boxes and containers is significantly lower than that of aluminum foil products. They will release harmful substances when they come into contact with high-temperature food, water or heated at high temperatures, which will affect human health.
