Because people in the market have been foolishly calling foil packaging products tinfoil or tin foil containers. So I have to correct this misunderstanding again. I want to justify the name of the safest and greenest foil packaging.
First, tin is the fourth most precious metal after platinum, gold, and silver. Pure tin is shiny, non-toxic and not easy to oxidize and discolor. It has good sterilization, purification and preservation effects. The chemical properties of tin are very stable. Tin is not easily oxidized by oxygen at room temperature. So it often maintains a silvery sheen.
Secondly, tin foil is a unique handicraft in China in the early years. In ancient times, its main use was to make money to worship ghosts and gods. Various other uses, such as sealing, are now available. The shape of ancient tin foil is rectangular or square, thin paper sheet, which can be folded and deformed. The color of the foil is silvery white. It turns golden yellow when burned.
Aluminum foil is made by rolling metal aluminum. The thickness of food packaging ranges from 0.006-0.3mm. Usually, tin foil packaging is also aluminum foil.
