Aluminum foil is commonly used for food storage, as it helps preserve freshness and prevents freezer burn. It's also used in cooking, either to cover dishes to retain moisture or to create packets for steaming or baking. In the kitchen, it's often used to line baking sheets to prevent food from sticking. Beyond cooking, aluminum foil is used for insulation, in arts and crafts, and even for cleaning purposes, such as buffing glass or polishing silverware. It's a versatile material found in many households and commercial settings.
