Aluminum foil refers to the paper made of aluminum foil backing paper and aluminum foil pasting. It is often used to wrap food. Most of the tin foil paper we use now is aluminum foil paper, so what is the difference between aluminum foil paper and tin foil paper?

Differences Between Aluminum foil and Tin Foil

1. Different materials
Aluminum foil is processed by metal aluminum or aluminum alloy through rolling equipment, and the general thickness is below 0.025mm. While tin foil is processed by metal tin or tin aluminum alloy through rolling equipment.

2. Different physical and chemical properties
The melting point of aluminum foil paper is 660 °C, and the boiling point is 2327 °C. The appearance is a silver-white light metal. It is ductile, and it can form an oxide film to prevent metal corrosion in the humid air. The melting point of tin foil is 231.89 °C, and the boiling point is 2260 °C. It has the characteristics of good corrosion resistance and low melting point. The appearance is silvery white and slightly blue metal.

3. Different Appearance
Tin foil is much brighter than aluminum foil. The tin foil sold is usually stacked one by one. There is cotton paper between each sheet. It is difficult to cut and the price is more expensive. While the aluminum foil is stiff and easy to cut, and rolls are often used. Cartridge packaging is cheaper, so it gradually replaced tinfoil and became the mainstream of the market. Tin is a soft metal with a specific gravity of 7.3 and a low melting point. A moderate amount is not poisonous. In extreme cases, it can be said that tin is poisonous. For example, some pots are plated on the inner wall. It is just that fire reacts with sulfur and halogens, and it will be corroded in acidic solutions of salts and so on.

4. Different poisoning reactions
Tin can irritate the stomach and aluminum can cause Alzheimer’s. Tin foil or aluminum foil is mostly used to wrap ingredients for grilling to prevent the meat from scorching. If you use them to wrap the ingredients and put them in the oven for grilling, there is little damage to the body. However, if seasoning sauce or lemon is added to the ingredients, the acidic substances in it will precipitate the tin and aluminum of the tin foil or aluminum foil. This will be mixed into the food and absorbed by the human body, which will cause the tin and aluminum poisoning of the consumer.

Which is better: Tin foil or aluminum foil?

Both aluminum foil and tin foil can be used to wrap ingredients for grilling, which prevent the meat from scorching and maintain the flavor of the ingredients. So which one should you choose when grilling?

Tin foil is softer than aluminum foil and has a lower melting point than aluminum foil. The temperature required for ordinary grilled food and baked food is relatively high. The aluminum foil needs to be melted at 660 °C, while the melting point of the tin foil is 231 °C, and it starts to melt when the temperature is above 160 °C. Therefore, the role of aluminum foil is more extensive. In addition, the price of aluminum foil is lower than that of tinfoil, so the aluminum foil is often used instead of tinfoil in modern times.

What are the functions of barbecue aluminum foil?

1、Serve as a container
Aluminum foil is equivalent to a receptacle, which can prevent more grease from dripping onto the charcoal fire to form smoke, and if the meat and grease remaining on the barbecue grill and grill continue to be heated without cleaning up, it is equivalent to eating paste, use tin foil. Grilling after wrapping can avoid this problem.

2、Heat insulation
Both aluminum foil and tin foil have the function of heat preservation and heat insulation. Wrap the baked ingredients in tin foil, which can keep warm for a long time without forming too much condensation water, which has a certain effect on maintaining the flavor of the barbecue.
