Tin foil will not break when exposed to open flames. Whether the tinfoil can be burned by fire depends on what temperature and how long it takes. Generally, the tin foil used for food will not burn out when it is wrapped in a fire or grilled. But burning a piece of tin foil directly on the fire will burn it out of shape, or it will melt out of shape. Tin foil paper will not burn when it meets an open flame, and it is resistant to high temperature. Mainly used in medicine, chemical industry, light industry, food, art supplies and handicraft production, such as decorative materials for advanced dry capacitors.

Tin foil, also called aluminum foil, is mainly used for cooking, holding food in the kitchen, or barbecue and wrapping food during barbecue. Now all the tin foil you buy in the supermarket is aluminum foil, which is made of aluminum and contains no tin. Tin foil is not tin, but aluminum. The main components of tin foil: aluminum content is 96.9 1%, and other components are oxygen, silicon, iron and copper.

Now in the process of making aluminum foil paper, the paper is coated to prevent aluminum from leaking directly, and no one cooks with aluminum foil every day, so there is no need to worry about excessive aluminum intake when using aluminum foil. Over the years, it has been widely used in food processing, such as canned food, soft drink packaging, potato chip packaging lining, shiny candy paper and so on.

Special use of tin foil

1, when baking food, in order to prevent the surface from being too dark, you can cover the food with tin foil, with the photosensitive surface facing up.

After the tin foil is covered, you are not afraid that the color of bread or biscuits will become darker, so that the heat radiation on the surface of the cake is uniform, which reduces the cracking on the surface and ensures that the food is cooked.

2, friends who often barbecue can use it to bake meat, so that the roasted meat is tender, smooth and moist.

3. You can also wrap the movable bottom die into a solid bottom die with tin foil, so that you can use the water bath baking method without buying a solid bottom die.

Difference between aluminum foil paper and tin foil paper

1, different materials and processes

Aluminum foil paper is made of metal aluminum or aluminum alloy by calendering equipment, and its thickness is generally below 0.025mm; Tin foil paper is made of metal tin or tin-aluminum alloy by calendering equipment.

2. Different physical and chemical properties

Aluminum foil paper has a melting point of 660℃ and a boiling point of 2327℃. It is a silvery light metal with good ductility, and can form an oxide film to prevent the metal from corroding in humid air. The melting point of tin foil paper is 23 1.89℃, and the boiling point is 2260℃. It has the characteristics of good corrosion resistance and low melting point, and its appearance is silvery white and slightly blue.

3. Different appearance characteristics

Tin foil paper is much brighter than aluminum foil paper. Sold tin foil paper is generally stacked one by one with cotton paper in the middle, which is difficult to cut and expensive. However, aluminum foil paper is hard, easy to cut, and most of them are barrels, so the price is relatively cheap, so it has gradually replaced aluminum foil paper and become the mainstream of the market.
