The main differences between tin foil and aluminum foil are as follows:
1. Production materials:
Tin foil is processed into a paper shape by stretching and pressing metal tin.
Aluminum foil paper is made by extruding metal aluminum or aluminum alloy into a paper shape.
2. Physical properties:
Hardness: Aluminum foil is usually harder than tin foil.
Smoothness: Aluminum foil is relatively smoother, while tin foil is relatively rougher.
Melting point: The melting point of tin foil is about 231.89 ℃, and the boiling point is about 2260 ℃; Aluminum foil has a high melting point of about 660 ℃ and a boiling point of about 2327 ℃. So aluminum foil is more stable in high temperature environments and is suitable for occasions that require high temperature resistance, such as barbecue, where aluminum foil is more suitable for use.
Ductility: Both have good extensibility, but tin foil may be relatively easier to fold.
3. Appearance: Generally speaking, aluminum foil paper appears more silver white compared to tin foil paper, while tin foil paper may have a slightly darker color.
4. Purpose:
Tin foil is commonly used to wrap food, which can have a certain preservation and insulation effect. It is also used in traditional crafts to make some handicrafts. Due to its low melting point, it easily melts when heated, making it less suitable for high-temperature cooking. However, it has the dual characteristics of thermal conductivity and insulation, and is commonly used in the cooking field for grilling meat, grilled fish, or keeping warm food.
Aluminum foil paper is more suitable for grilling food due to its high melting point, which can prevent it from being burnt or burned; Widely used in the packaging field, such as aviation food, meat, cigarette packaging and other products, its excellent barrier properties, moisture and water resistance, and fragrance retention are highly favored; It also has applications in the field of construction, which can be used to improve the construction efficiency and aesthetics of insulation materials.
5. Market price: Under the same specifications and quality, the price of aluminum foil paper is usually lower than that of tin foil paper, mainly because aluminum resources are relatively more abundant and production costs are lower.
