Tinfoil

Tinfoil is a thin, flexible sheet of metal, traditionally made of tin, but now almost exclusively made of aluminum. It is commonly used for wrapping food, protecting surfaces, and crafting. Its ability to be easily molded and its barrier properties against light, oxygen, moisture, and odors make it a versatile material. Historically, 'tinfoil' referred specifically to tin-based foil, but the term persists even though aluminum has superseded tin in its manufacture, largely due to its lower cost and greater availability.
