Aluminum foil can withstand high and low temperature (- 20 ℃ - 250 ℃) packaging materials with stable molecular structure. It can go from freezer to oven to dining table without changing containers. Compared with the plastic fast food box commonly used at present, it can only bear the temperature range of - 16 ℃ to 85 ℃. The shiny surface of aluminum foil is still bright after being used in the multi-functional oven for many times, and the food can maintain its color and taste at the same time.
