Are aluminium foil lunch boxes harmful to health?

With the development of the times, more and more businesses are using aluminium foil products to pack food and the use of aluminium foil lunch boxes is becoming more and more widespread, even replacing plastic boxes. People know that using plastic boxes to pack food can be harmful to their health. But how much do people know about aluminium foil boxes? Is aluminium a metal element that can damage your health if you use food in aluminium foil containers for a long time?

Aluminium foil is compressed directly from metallic aluminium to make it thin. According to the national standard "Refined aluminium foil", the toxic elements in aluminium foil should comply with the following regulations: lead: no more than 0.01%, cadmium: no more than 0.01% and arsenic: no more than 0.01%. Therefore, the best choice for packaging for barbecues, food, etc. is high-quality aluminium foil, and its lead content should comply with national standards. Aluminium is a very active metal and it is easily oxidised by oxygen in the air at room temperature and pressure to produce aluminium oxide, which is a dense protective film that prevents further corrosion of aluminium by some substances. The aluminium oxide is a dense protective film that prevents further corrosion of the aluminium by certain substances. The aluminium foil lunch boxes are also coated and are completely chemically neutral in the air, so they do not produce toxic substances and can be used with confidence. However, it is important to note that it is not advisable to store acidic food in aluminium foil containers, as this can damage the oxidation layer on the surface and accelerate corrosion.
