Aluminum foil liners

Aluminum foil liners are thin sheets of aluminum with a shiny coating, commonly used in the kitchen to wrap food, cover pans and containers, or for baking and grilling. Their main function is to retain moisture, protect food from direct contact with heat, and prevent sticking or burning.

This material originated in Switzerland at the beginning of the 20th century and has since become popular worldwide for its versatility and durability in the kitchen. Aluminum foil is waterproof, resistant to extreme temperatures, and easy to mold to fit different shapes and sizes.

Among its properties, its ability to reflect heat stands out, which helps cook food evenly, and its protective function against external contamination. Furthermore, by preserving moisture, it intensifies flavors and maintains the ideal texture of the preparations.

In the Spanish-speaking world, besides aluminum foil liners, they are also known as aluminum foil, aluminium foil, or simply foil in culinary contexts.
