Aluminum foil, or tin foil, is a paper-thin, shiny sheet of aluminum metal. It’s made by rolling large slabs of aluminum until they are less than 0.2 mm thick.
It’s used industrially for a variety of purposes, including packing, insulation and transportation. It’s also widely available in grocery stores for household use.
At home, people use aluminum foil for food storage, to cover baking surfaces and to wrap foods, such as meats, to prevent them from losing moisture while cooking.
People may also use aluminum foil to wrap and protect more delicate foods, like vegetables, when grilling them.
Lastly, it can be used to line grill trays to keep things tidy and for scrubbing pans or grill grates to remove stubborn stains and residue.
