The present invention relates to an extruded matt foil comprising at least one layer in which glass beads are uniformly distributed in a polymer matrix comprising at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil of the present invention is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high- pressure laminates(HPLs).
