Aluminum foil, iron foil, and tin cans are used for metal packaging. When using aluminum foil, rarely used alone, and plastic film adhesive together. Most of the surface of the can is covered with plastic. Therefore, heavy metals and some compounds in additives migrate into food, affecting food safety.

Food glass container packaging materials

Glass is also a kind of inorganic melt, mainly composed of SiO2-Na2O. Because of the different types of glass, there are leaches from the raw materials.

Besides, the coloring of food packaging materials requires the use of metal salts. If heavy metals migrate into the food, it will also affect food safety and pose unsafe risks
