The low weight of film, paper or other 2D fractions reduces the potential throughput performance of sensor-based sorting units. NIR scanners only detect the surface of the supplied objects. All objects must lie separately on the belt and overlapping of objects must be prevented for good performance. All manufacturers' NIR separators need a "mono-layer" for optimal performance.
This is less of a problem for applications using 3D material, since transfer of the objects onto the acceleration belt usually ensures sufficient separation.
