Most people have always referred to aluminum foil packaging products as tin foil or tin foil containers. But in fact, aluminum paper and tin foil paper are different. Today, I will correct this misunderstanding and rectify the name of the safest and environmentally friendly aluminum foil packaging.
First of all, tin is the fourth precious metal behind platinum, gold and silver. Pure tin is luster, non-toxic, not easy to oxidize and discolor, and has good sterilization, purification and freshness preservation effects. The chemical properties of tin are very stable and are not easily oxidized by oxygen at room temperature, so it often maintains a shiny silver luster. Note: Pure tin is non-toxic, and people often plate it on the inner wall of the copper pot to prevent the copper warm water from generating toxic patina.
Toothpaste shells are also commonly made of tin (the toothpaste shell is made of two layers of tin with a layer of lead in the center). In recent years, the market has gradually replaced tin with aluminum to make toothpaste shells.
Aluminum foil is produced by rolling aluminum metal. It is characterized by smooth surface, light weight, good shading, non-corrosive, non-toxic, and easy to process. The thickness of aluminum foil sheet sed in food packaging ranges from 0.006-0.3mm. For example, disposable lunch boxes used on airplanes are made of aluminum foil and can be placed in a microwave or oven to heat meals. The tin foil packaging that everyone usually says is also aluminum foil.
Aluminum foil has more advantages in food packaging applications than tin foil. I hope everyone will call it aluminum foil paper or aluminum foil packaging in the future.
