Tin foil VS aluminium foil
Cosmetic seals are generally made of tin foil. But most of the metal components of tin foil are actually aluminum, not tin.
The difference between the two is as follows:
1. Color and physical properties are different:
Tin foil is much brighter than aluminum foil, but the ductility of tin is very poor. The aluminum foil material is relatively stiff, good for cutting, and more uses reel type packaging, the price is cheaper, and now it is gradually becoming the mainstream in the market.
2. Different chemical properties:
The foil is very well insulated and the foil has good finish and heat reflectivity. Aluminum foil paper is a paper obtained by bonding aluminum foil backing paper and aluminum foil paste. Soft and easy to change, like paper, and does not rebound after deformation. Can be qualitative, to ensure that the shading, not falling, opaque, no pollution, the price is cheap.
3. The usage is roughly the same:
Tin foil is mainly used in kitchens for cooking, holding food, or for making materials that can be easily cleaned.
Aluminum foil is used to protect and package food, cosmetics and chemicals.
