Metal foil is a thin sheet made from various metals, commonly aluminum or copper. It is often used in packaging, insulation, and cooking due to its lightweight and malleable properties. Metal foil can easily be shaped and is resistant to moisture and light, making it ideal for preserving food and protecting products. In addition to its practical uses, metal foil is also employed in arts and crafts. Artists use it to create intricate designs and add a shiny finish to their work. The reflective quality of metal foil enhances visual appeal, making it a popular choice in decorative applications.
