The earliest tinfoil was indeed made of tin, but food wrapped in tin would more or less have a tin smell, and the cost was relatively high. Later, it was basically replaced by aluminum. So what is the difference between tinfoil and aluminum foil?
1. Material and thickness: Tin foil is made of an alloy of tin and aluminum, while aluminum foil is made of pure aluminum. Therefore, aluminum foil is thinner and lighter than tin foil. The cost of tin is relatively high, and later it was basically replaced by aluminum. However, since there is no big difference between the two in appearance, the name tin foil has been used.
2. Price: Since tin foil contains tin, its price is higher than that of aluminum foil. The tin foil sold in supermarkets is usually stacked one by one, with cotton paper between each sheet. It is difficult to cut and the price is relatively expensive. The material of aluminum foil is relatively stiff, and it is mostly packaged in rolls, and the price is relatively cheap.
3. Different appearance and characteristics: The surface of tin foil is silvery white, while the surface of aluminum foil has a metallic luster. Tin foil is softer and easier to fold than aluminum foil. How to distinguish tin foil from aluminum foil? Aluminum foil looks much brighter than tin foil, but the ductility of tin is very poor and it breaks when pulled.
4. Uses: Both tinfoil and aluminum foil can be used to wrap food to prevent it from drying out and spoiling. Tinfoil can also be used to wrap hot food.
