Abstract

A method for providing a film laminate comprising a substrate and a polymer film, and suitable for forming a part of a laminated packaging material is provided. The method comprises forwarding a web of the substrate to pass through a lamination nip. The method further comprises casting the polymer film by applying a molten polymer material onto a cooling roller to at least partially solidify the molten polymer material to form the polymer film. Furthermore, the method comprises directly forwarding the polymer film to pass through the lamination nip, thereby laminating the polymer film onto the web of the substrate.
