Abstract: Disclosed herein are a metal-polymer laminate structure having an enhanced flame protection function as well as a method for preparing the same. The metal-polymer laminate structure includes a metallic layer, at least one polymeric layer provided on the metallic layer, and a backing layer provided on the at least one polymeric layer. The at least one polymeric layer includes an intumescent material, and a first functional layer is interposed between the metallic layer and the at least one polymeric layer. The first functional layer is a thermoplastic layer constructed from a material selected from polyamide, thermoplastic polyurethane, hotmelts, preferably polyamides such as PA6, PA6/6.36, PA6/66, PA12, PA6.12, PA6.10, PA6I/6T, copolymers of caprolactam or lauryllactam, thermoplastic polyurethane, and polyether block co-polyamides or combinations thereof.
