在層層的工序中，鋁箔由原鋁合金軋制而成，不含重金屬等的有害物質。鋁箔生產過程中，采用高溫退火消毒工藝。結果，鋁箔能安全地與食物接觸，不含和促進細菌生長。多數(shù)情況下，鋁箔不會與食物發(fā)生反應。但是，市場上有不少塑料餐盒，都是用來源不明的原料，甚至是假貨、廢塑料制作的，質量和可靠性難以保證。一次性塑料餐具生產中如添加碳酸鈣、滑石粉、工業(yè)石蠟、回收廢品等，極易造成產品蒸發(fā)殘留(正己烷)超標。為了保護環(huán)境，防止增塑劑對社會和人體造成危害，部分地方政府也出臺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.

鋁箔的高導電性使得與食品加工、冷藏和二次加熱有關的時間和能量都可以被減少。金屬箔的熱穩(wěn)定性好。鋁箔容器在加工、包裝過程中，能夠承受較高的溫度變化。結果表明，分子在-20°C-250° C時，分子結構穩(wěn)定，無變化。其適用溫度范圍可從快速冷凍到極端烘烤和燒烤。同時，鋁箔不會變形、開裂、熔化或燃燒，不產生任何有害物質。

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.

使用鋁箔將高溫炭火與煙氣隔開，以避免食物燃燒產生致癌物質。鋁箔餐盒和容器非常適合高溫滅菌和熱密封。鋁箔餐盒的加熱方式有多種，包括各種烤箱、烤爐、無氧加熱柜、蒸鍋、蒸鍋、蒸箱、微波爐(必須放在光波和燒烤檔)、壓力鍋用鋁箔加熱食品。

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.

與此相反，塑料餐盒和容器的高溫耐熱性大大低于鋁箔制品，在高溫下加熱時會釋放出有害物質，影響人體健康。(發(fā)泡餐盒是用聚苯乙烯原料制成的。聚苯乙烯原料的軟化點在87~97℃之間。所以，不能用于80℃以上的高溫環(huán)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較軟。正常使用溫度在-6度至+90度之間。早先流行的泡沫塑料餐盒現(xiàn)在已被市場淘汰。據(jù)執(zhí)法人員介紹，泡沫飯盒原料含有有害物質。泡沫塑料中的有害物質一旦裝入高溫高油食品，極易在食品上沉淀、遷移、凝結，并隨食品進入人體。給身體帶來傷害。此外，由泡沫塑料制成的一次性飯盒不易降解，多年不腐爛，燃燒時釋放大量有害氣體，嚴重破壞環(huán)境。因此，從2001年開始，中國完全禁止生產、銷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.
