Because the domestic market has been stupidly calling aluminum foil packaging products tin foil paper or tin foil containers, I must once again correct this misunderstanding and rectify the name of the safest and most environmentally friendly aluminum foil packaging!
First of all, tin is the fourth precious metal after platinum, gold and silver. Pure tin is shiny, non-toxic, not easily oxidized and discolored, and has good sterilization, purification, and preservation effects. The chemical properties of tin are very stable and are not easily oxidized by oxygen at room temperature, so it often maintains the shining luster of silver. Note: Pure tin is non-toxic. People often plate it on the inner wall of copper pots to prevent warm copper water from forming 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 middle. In recent years, my country has gradually used aluminum instead of tin to make toothpaste shells).
Secondly, tin foil paper is a unique handicraft product of Shaoxing in the early years. In ancient times, its main use was to make money to worship ghosts and gods. It now has a variety of other uses, such as sealing. The shape of ancient tinfoil paper is rectangular or square, thin paper sheet-like, and can be folded and deformed. The color of tin foil is silvery white, and the ashes are golden after burning. Its main components are tin and aluminum, which are alloys of tin and aluminum. Not suitable for food packaging!
Aluminum foil is produced by rolling aluminum metal. The thickness range used in food packaging is 0.006-0.3mm. For example, the disposable lunch boxes used on airplanes are made of aluminum foil and can be placed in a microwave or oven to heat meals. Generally speaking, tin foil packaging is also aluminum foil.
Aluminum foil has many superior properties in food packaging. People who eat melons can read our other articles to share.
I hope everyone will call it aluminum foil or aluminum foil packaging in the future!
