Answer--- ❒

✭ Aluminum foils is made up of aluminum, which has reflective properties and acts as a barrier to light and oxygen. As a result, the foil reflects the thermal energy back to the food maintaining the inherent aroma, moisture and flavour of the food. It is often used for packaging of perishable foods and dairy products also for longer storage. Aluminum foil’s usage doesn’t only limit to food, it can also be used to put on windows to keep the house cool during summer and hot during winters.
