foilalumiini

Foilalumiini, commonly known as aluminum foil, is a thin sheet of aluminum metal produced by rolling processes at specialized mills. It is typically less than 0.2 millimeters (0.0079 inches) thick, with thinner gauges often referred to as "heavy foil" (thicker than 0.016 mm), "standard foil" (thicker than 0.006 mm), and "household foil" (thicker than 0.006 mm). The manufacturing process involves passing aluminum through rolling mills multiple times to achieve the desired thinness and temper.

The primary properties that make foilalumiini useful are its malleability, impermeability, and barrier properties. It is easily shaped and conforms to various forms, making it ideal for wrapping food. Its non-porous nature prevents the passage of gases, liquids, and light, which helps preserve food and other sensitive materials. The reflective surface of foilalumiini also plays a role in its applications, particularly in insulation and packaging where it can reflect radiant heat.

Foilalumiini has a wide range of applications. In the kitchen, it is used for cooking, grilling, baking, and storing food. It is also employed in industrial settings for insulation, protective wrapping of sensitive electronic components, and in the manufacturing of capacitors. Its use extends to pharmaceuticals and cosmetics for packaging and hygiene purposes. Recycling foilalumiini is common, contributing to its sustainability as a material.
