Why is the box lunch of passenger plane packed with tin foil?
Because the food on the passenger plane is heated by microwave oven, the tin foil will not be used to speed up the heating, let alone to keep warm. Because of the characteristics of tin, it can prevent some microwaves from entering the food, delay and balance the heating, and prevent the food from being stiff inside but the weak area outside has been scorched due to rapid heating. It is a truth to bake chicken products in a microwave oven at home. The instructions will require that the chicken wings be wrapped in tin foil to prevent the wing tips from being burnt or dehydrated excessively.
