What is made out of Tetra pak?

Tetra Pak is primarily made from a combination of materials, including paperboard, polyethylene, and aluminum. The paperboard provides structure and strength, while the polyethylene layers create a barrier against moisture and air, and the aluminum layer offers protection from light and oxygen. This composite material is commonly used for packaging liquid foods, such as milk, juice, and soups, ensuring they remain fresh and safe for consumption without refrigeration.
