1. Tin foil is just Hong Kong’s name for aluminum foil. The melting point of tin is only 232 degrees, and many ovens can reach 250 degrees or more. If tin is used as a material, it will melt.
2. The so-called tin foil is aluminum foil, definitely not tin. The melting point of aluminum is 660 degrees, which is far higher than the temperature of most household ovens and will not melt during use.
Aluminum foil and tin foil are easy to distinguish. Tin foil is much brighter than aluminum foil, but it has poor ductility and breaks when you pull it. Aluminum foil is relatively stiff and is mostly packaged in rolls, which is cheaper.
Special reminder for aluminum foil barbecue
If seasoning sauce or lemon is added to the food, the acidic substance contained in it will precipitate the tin and aluminum of the tin foil or aluminum foil, which will easily be mixed into the food and be absorbed by the human body, thereby causing tin and aluminum poisoning in the eater. If people with kidney disease have too much aluminum, anemia can occur. It irritates the stomach and intestines, and aluminum can cause dementia. Therefore, it is recommended that people do not add seasoning sauce or lemon if they want to wrap the food with tin foil or aluminum foil when making grilled food. In addition, it is safer to use cabbage leaves, corn leaves instead of tin foil or aluminum foil, or to use bamboo shoots, water chestnuts, and vegetable leaves as a base.
Aluminum foil is a healthy packaging, there is no lead component
“Theoretically speaking, lead will not be artificially added to aluminum foil, because after adding lead, the aluminum will become hard, the ductility is not good enough, and it is not conducive to processing, and the cost of lead is more expensive than aluminum!” There is no lead in it, how can lead be precipitated during use? There may be another possibility: aluminum foil paper is produced from recycled aluminum. Recycling aluminum may be more complicated. But the specifics still have to be tested by experiment. In some aluminum foil papers, the aluminum content accounts for 96.91%, 94.81%, 96.98%, and 96.93% of the total weight respectively. Some aluminum foils also contain oxygen, silicon, iron, copper and other ingredients, but at most they account for a few percent, which can almost be ignored. So far, the truth is clear: the most important component of all kinds of aluminum foil is aluminum, and there is no shadow of lead at all.
