在层层的工序中，铝箔由原铝合金轧制而成，不含重金属等的有害物质。铝箔生产过程中，采用高温退火消毒工艺。结果，铝箔能安全地与食物接触，不含和促进细菌生长。多数情况下，铝箔不会与食物发生反应。但是，市场上有不少塑料餐盒，都是用来源不明的原料，甚至是假货、废塑料制作的，质量和可靠性难以保证。一次性塑料餐具生产中如添加碳酸钙、滑石粉、工业石蜡、回收废品等，极易造成产品蒸发残留(正己烷)超标。为了保护环境，防止增塑剂对社会和人体造成危害，部分地方政府也出台了限制使用一次性不可降解塑料餐具的措施。

In the process of layers, the aluminum foil is rolled from the original aluminum alloy and does not contain harmful substances such as heavy metals. High temperature annealing disinfection process is adopted in the production of aluminum foil. As a result, aluminum foil can safely come into contact with food, free of and promote the growth of bacteria. In most cases, aluminum foil will not react with food. However, many plastic lunch boxes on the market are made of raw materials from unknown sources, even fake goods and waste plastics, so it is difficult to ensure the quality and reliability. Waste products such as hexane and talc in the production of tableware are easy to be recycled due to excessive evaporation of waste products such as hexane and talc. In order to protect the environment and prevent plasticizers from causing harm to society and human body, some local governments have also introduced measures to restrict the use of disposable non degradable plastic tableware.

铝箔的高导电性使得与食品加工、冷藏和二次加热有关的时间和能量都可以被减少。金属箔的热稳定性好。铝箔容器在加工、包装过程中，能够承受较高的温度变化。结果表明，分子在-20°C-250° C时，分子结构稳定，无变化。其适用温度范围可从快速冷冻到极端烘烤和烧烤。同时，铝箔不会变形、开裂、熔化或燃烧，不产生任何有害物质。

The high conductivity of aluminum foil can reduce the time and energy related to food processing, refrigeration and secondary heating. Metal foil has good thermal stability. Aluminum foil containers can withstand high temperature changes in the process of processing and packaging. The results show that the molecular structure is stable and unchanged at - 20 ° C-250 ° C. Its applicable temperature range can range from quick freezing to extreme baking and barbecue. At the same time, the aluminum foil will not deform, crack, melt or burn, and will not produce any harmful substances.

使用铝箔将高温炭火与烟气隔开，以避免食物燃烧产生致癌物质。铝箔餐盒和容器非常适合高温灭菌和热密封。铝箔餐盒的加热方式有多种，包括各种烤箱、烤炉、无氧加热柜、蒸锅、蒸锅、蒸箱、微波炉(必须放在光波和烧烤档)、压力锅用铝箔加热食品。

Use aluminum foil to separate high-temperature carbon fire from flue gas to avoid carcinogens caused by food combustion. Aluminum foil lunch boxes and containers are very suitable for high temperature sterilization and heat sealing. There are many heating methods for aluminum foil lunch boxes, including various ovens, ovens, anaerobic heating cabinets, steamers, steamers, steamers, microwave ovens (which must be placed in the light wave and barbecue file), and pressure cookers, which use aluminum foil to heat food.

与此相反，塑料餐盒和容器的高温耐热性大大低于铝箔制品，在高温下加热时会释放出有害物质，影响人体健康。(发泡餐盒是用聚苯乙烯原料制成的。聚苯乙烯原料的软化点在87~97℃之间。所以，不能用于80℃以上的高温环境。

On the contrary, the high-temperature heat resistance of plastic lunch boxes and containers is much lower than that of aluminum foil products. When heated at high temperature, harmful substances will be released and affect human health. (the foamed lunch box is made of polystyrene raw material. The softening point of polystyrene raw material is between 87 ~ 97 ℃. Therefore, it cannot be used in high temperature environment above 80 ℃.

可供使用的塑料餐盒主要有 PP和 PS聚苯乙烯。PP较软。正常使用温度在-6度至+90度之间。早先流行的泡沫塑料餐盒现在已被市场淘汰。据执法人员介绍，泡沫饭盒原料含有有害物质。泡沫塑料中的有害物质一旦装入高温高油食品，极易在食品上沉淀、迁移、凝结，并随食品进入人体。给身体带来伤害。此外，由泡沫塑料制成的一次性饭盒不易降解，多年不腐烂，燃烧时释放大量有害气体，严重破坏环境。因此，从2001年开始，中国完全禁止生产、销售和使用泡沫塑料餐具。

The available plastic lunch boxes mainly include PP and PS polystyrene. PP is soft. The normal operating temperature is between - 6 ° C and + 90 ° C. The popular foam plastic lunch boxes are now out of the market. According to law enforcement officers, foam lunch box raw materials contain harmful substances. Once the harmful substances in foam plastics are loaded into high temperature and high oil food, they are easy to precipitate, migrate and coagulate on food, and enter the body with food. Bring harm to the body. In addition, disposable lunch boxes made of foam plastics are not easy to decompose, do not rot for many years, release a lot of harmful gases when burning, and seriously damage the environment. Therefore, since 2001, China has totally banned the production, sale and use of foam plastic tableware.
