Tin foil will not break in an open flame. 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.

Matters needing attention

Don't touch the naked flame directly, don't put it in the microwave oven for heating easily, and only follow the instructions under the barbecue function of the microwave oven. At the same time, it is also necessary to avoid that foods and seasonings wrapped in tin foil contain too strong acidic substances and contact with tin foil for a long time to avoid the dissolution of harmful substances.

Putting tin foil on the barbecue grill will lead to lead pollution. Lei Zurong, a food safety expert and senior engineer in Hubei Province, said that tin foil used for food packaging has strict requirements on the materials used. Many tin foil papers sold in the market now are aluminum foil papers. Both sides of the paper are plastic or special paint, and the middle layer is aluminum.
