In the production process of non stick cooking foil, there are multiple processes such as rolling, finishing, annealing, packaging, etc., and the interlocking production process. Problems in any link may lead to quality problems of aluminum foil.
As people’s understanding of non stick cooking aluminum foil is getting deeper and deeper, the usage rate and production demand of aluminum foil are also soaring. Includes BBQ, foil, lunch box. Most aluminum foils are shiny on one side and matte on the other. Foods can be wrapped with aluminum foil on both sides. Usually, it is recommended to wrap them with a glossy side to improve heat conduction.
The original tin foil is really made of tin. The tin foil is softer than aluminum foil, and the wrapped food will have a little tin smell. At the same time, the tin foil cannot be heated due to its low melting point, or it begins to become brittle when the heating temperature is above 160°C. It limits its use in food packaging. If you need to grill food, you cannot use tinfoil when baking food. Since the introduction of aluminum foil paper, because of its high melting point, it starts to melt when heated to above 660 ° C. It can be applied to ordinary barbecue food, baked food, and even traditional beggar chickens use aluminum foil paper to wrap and bake, which is clean and hygienic at the same time. Original flavor. Therefore, after the price of aluminum was reduced, aluminum foil replaced tin foil in daily life.
