alumíniumfólia

Alumíniumfólia, commonly known as aluminum foil, is a thin, flexible sheet of aluminum metal produced by passing aluminum through a rolling mill. It is typically 0.016 to 0.2 millimeters thick. Its primary characteristic is its thinness and malleability, making it easily conformable to various shapes.

The production process involves cold rolling, where the aluminum is passed between rollers at room temperature. This process hardens the metal and reduces its thickness to the desired level. The final product can be shiny on one side and dull on the other due to the rolling process.

Alumíniumfólia is widely used in kitchens for cooking, wrapping, and preserving food. Its reflective properties help retain heat, making it useful for baking and roasting. It also acts as a barrier against moisture, light, and odors, extending the shelf life of food products. Beyond culinary applications, it finds uses in insulation, packaging for electronics, and even in some artistic endeavors due to its pliability. It is generally considered safe for food contact when used as intended.
