Laminated Steel is a composite material made by bonding polymer films—typically PET or PP—to a thin steel substrate such as tinplate (ETP), tin-free steel (TFS), or cold-rolled base metal. This lamination process enhances corrosion resistance, eliminates the need for traditional coating (e.g., BPA-based lacquers), and provides excellent barrier properties for packaging and industrial applications.
