Sometimes severe lead poisoning can lead to insomnia and headaches. Tin foil boxes for food packaging have strict requirements for the materials used. Many of the tin foil sold on the market now is aluminum foil. Both sides of the paper are made of plastic or special coatings, and the middle layer is made of aluminum. If it's just packaged food, it's okay, but if it's wrapped in food and baked directly over fire, it's directly harmful to the human body.
2. Heavy metal pollution. However, it has not been confirmed whether baking in a tin foil box can isolate carcinogens. But whether or not it has the function of isolating carcinogens, tin foil is prone to causing heavy metal pollution.
3. Lead poisoning. Because aluminum contains a large amount of lead, once the stability of aluminum foil is not up to standard or comes into direct contact with open flames, it is likely that lead will dissolve. If people frequently consume this contaminated food, it will affect the normal operation of the human nervous system, hematopoietic system, cardiovascular system, and digestive system. Although baking with a tin foil box will not cause poisoning to the human body, baking with an open flame can have an impact on the human body.

3. The tin foil of the tin box is made of tin. Tin foil is softer than aluminum foil, and there is a slight tin smell when wrapping food. At the same time, the melting point of tin foil is low and cannot be heated. Otherwise, if the heating temperature exceeds 160, it will become brittle, limiting its use in food packaging. If you need to barbecue food, tin foil boxes cannot be used when grilling food.
