What Is Metallic Paperboard?
Metallic paperboard, also known as gold and silver paperboard or metalized cardboard, is a specialty paperboard material produced by applying a thin metallic layer onto a paper substrate.
The structure of metallic paperboard is similar to a three-layer “sandwich”:
Base Paperboard Layer
The bottom layer is usually made from white cardboard, coated paper, or art paper. It provides the basic stiffness, strength, and structural support required for packaging production.
Aluminum Metallized Layer
The core feature of metallic paperboard is its aluminum coating. Through a vacuum metallization process, aluminum vapor is deposited onto the paper surface, forming a smooth and highly reflective metallic finish.
This layer creates the signature gold, silver, or holographic appearance that makes products stand out.
Protective Coating Layer
A protective coating is applied to improve surface durability, protect the metallic layer, and enhance printing performance. It also helps achieve better results during post-printing processes.
