It is widely used in cooking and food storage due to its ability to withstand high temperatures and its effectiveness in preserving food freshness. Foil can be used to wrap food for baking, grilling, or roasting, cover dishes to retain moisture, and store leftovers to maintain their flavor and prevent contamination.
