Aluminum foil’s formability, strength and ability to ensure product freshness make it an ideal material for many forms of packaging — maybe a swan shaped foil container holding your leftovers comes to mind?
Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria...allowing us to safely store perishable goods for long periods without refrigeration.
But you'll find foil in more than just your pantry. An incredibly efficient insulator and reflector of energy, aluminum foil is used widely in modern HVAC heat exchangers. It even helps shield fiber-optic cables against magnetic and radio frequency emissions.
