Aluminum foil wraps burritos, physics equipment and the highlighted tresses of hair-salon customers. It forms flexible ducts and lasagna pans, lines cigarette packs and fast-food sandwich wrappers. It hides between layers of film in flexible packaging. It protects aspirin bottles from tampering, petri dishes from light and tractor engines from overheating. It tops yogurt cups and peanut cans. It backs blister packs of antihistamines, antacids and birth-control pills. It goes into automotive parts and air-conditioning systems.

U.S. manufacturers rely on aluminum foil. So do nail salons, building contractors and bakeries.
