The material of the intermediate isolation layer 83 is aluminum foil, which is used to provide high barrier performance to prevent the penetration of oxygen, light, and moisture, and protect the internal liquid food from oxidation and deterioration. The material of the printing layer 85 is bleached kraft paper, which is used to provide a printing surface for printing brand logos, product information, etc. The first adhesive layer 82 and the second adhesive layer 84 are used to firmly bond the outer paper, aluminum foil, and inner plastic film together respectively to ensure the integrity of the package.
