From Wikipedia
Liquid packaging board (LPB) is a type of composite paperboard used to make cartons that hold liquids. LPB is used extensively for packages that hold beverages such as milk or juice. Paperboard packages are often used in combination with aseptic processing techniques to produce shelf-stable products, including the Tetra Pak brand of paperboard containers. Liquid packaging board is manufactured from multiple layers of paper, combined with layers of other materials such as aluminium foil or plastic. This layering gives LPB excellent wet strength, which is essential for preserving the quality of the product within the LPB packaging. Only virgin paper fibers are used. The barrier coating must hold the liquid and prevent migration of air and flavors through the paperboard.
