A specialty base paper designed for the vacuum metallizing process, also known as metallizing base paper or vacuum metallizing base paper. It is produced by treating ordinary paper with special processes, resulting in a surface that is smooth, dense, high in strength, and low in air permeability. It allows for the direct deposition of an extremely thin aluminum layer in a vacuum environment to form metallized paper.
