Abstract: Rear-side film for solar modules, which are embedded in EVA (ethylene-vinyl acetate copolymer) which are transparent and cross-linked at a temperature of more than 140° for rear-side film applied to the rear side of the EVA and hence binding same, wherein the rear-side film consists in a multi-layer construction comprising co-extruded layers of polyolefin that are directly connected with each other, of which layers a front layer comprising a layer thickness of less than 100 ?m is filled with pigments or reflecting particles in a weight proportion up to 20% and reinforced with subsequent layers to an overall strength of the rear-side film of over 300 ?m, wherein the layers consist overall or with a mixture proportion of non-cross-linked polypropylene, wherein the layers lying behind the front layer are filled at least partially with an inorganic stabilising filler with a weight proportion of up to 40% relative to the weight of the rear-side film, and a method for producing a rear-side film.
