When we cook barbecue food, we usually use tin foil or aluminum foil. Metal tin itself is not toxic, and only simple tin compounds and tin salts have low toxicity. If it is an organotin compound, it will still be toxic. This also makes many people worry that baking with tin foil will be bad for their health, but if you buy regular tin foil products, you don't have to worry about this problem, and the main component of food-grade tin foil is actually aluminum, that is, aluminum foil.

Moreover, aluminum has been used for many years and is widely used in food packaging, such as cans, soft drink packaging, potato chip packaging liner, shiny candy paper and so on.
