The so-called "tin foil" we use now is mostly made of aluminum foil. The original tin foil was actually made of tin. But the melting point of tin is only 231.89°C, and most ovens can reach above 250°C. The melting point of aluminum foil is above 660°C, which can be used for grilling or baking, and the cost of aluminum is lower, so it completely replaces the status of tin foil.

When using aluminum foil, many people still have a question: Should I use matte or glossy bread food? In the production process, because the aluminum foil paper is very thin, in order to prevent it from being broken, the manufacturer generally uses two layers to press it at the same time. When the two layers of aluminum foil are in contact with each other, friction will inevitably occur, so a matte surface is formed; while the other side is directly in contact with a smooth machine, a smooth surface will be formed. The time for heating food on both sides is not much different, the reflectivity of the matte side is 80%, and the reflectivity of the glossy side is 88%, both of which can be used. But it is recommended to use the matte side to directly contact the food, because the glossy side is more likely to stick to the food.

Aluminum foil paper is widely used, such as aviation food packaging, ordinary meat packaging, cigarette packaging, etc. Among the aluminum foil products in my country, the largest production scale is packaging aluminum foil products, accounting for nearly 50% of the total output. Today, due to its many advantages and characteristics such as easy recycling, green environmental protection, water resistance, high temperature resistance, etc., packaging aluminum foil has gradually attracted the attention of merchants and consumers. Aluminum foil consumption accounts for 37% of the total consumption of aluminum foil. It is expected that in the future, with the application With the expansion of the scene, there is still huge room for development of packaging aluminum foil.
