Food wrapping refers to the practice of covering or enclosing food items to protect them from contamination, spoilage, and drying out. Common materials used for food wrapping include plastic wrap, aluminum foil, and wax paper. These materials help maintain the freshness and quality of food, making it easier to store and transport. In addition to preserving food, wrapping can also enhance presentation, especially for items like sandwiches or gifts. Proper food wrapping techniques can prevent odors from spreading in the refrigerator and keep different food items from affecting each other's taste.
