Definition

Foil is a thin, flexible sheet of metal, typically aluminum, used for wrapping or covering things. It acts as a barrier against light, moisture, and odors. Think of it as a metal skin. Unlike plastic wrap, foil is impermeable to oxygen and can withstand high temperatures. It's commonly used in cooking, packaging, and insulation.

Etymology

The word 'foil' comes from the Old French word 'foille,' meaning 'leaf' or 'sheet.' It ultimately derives from the Latin word 'folium,' meaning 'leaf.' The term reflects the thin, leaf-like nature of the material.
