The invention relates to a method for coextrusion of at least two molten material flows having different composition by separating the molten material into at least two molten material flows, admixing additives in at least one of the molten material flows and bringing together the molten material flows by coextrusion in one or more extrusion tools. The method is particularly suitable for the production of PVB films with a color strip for composite glazings.
