Abstract:
1. A method of producing a multi-layer composite foil, said method comprising: providing a cover layer comprising at least one sub-layer; extruding a material including at least one of acrylonitrile butadiene styrene copolymers, acrylonitrile butadiene styrene copolymers with admixtures, polystyrene, polystyrene with admixtures, high-impact polystyrene, polyester, amorphous polyester copolymer so as to form at least two carrier layers; arranging the at least two carrier layers under the cover layer to form the composite foil; and ensuring that the composite foil has a tensile strength sufficient to achieve a maximum tensile force between 30 Newton and 280 Newton in a single-axis tensile testing procedure using the composite foil as a testing body, wherein said ensuring comprises performing the single-axis tensile testing procedure using the following sub-steps:
