Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technique capable of enhancing film removal rate and recycling rate in film removal processing in the state that a various kinds of coated resin products are mixed. SOLUTION: The film removal and sorting method has a film removal step S5 of removing the film from a substrate by heating up the material to be treated constituted by mixing a plurality of kinds of coated resin products in which the softening temperature of the films and the substrate is different to the temperature in which the films or the substrate is softened without being melt, a sorting step S9 of sorting the material to be treated from which the film is removed is sorted to one which the films are left and one in which films are removed, film removal step is carried out by heating up the material to be treated to a first softening temperature lowest of either one of softening temperatures of the film or the substrate, thereafter the sorting step is carried out sorting it to one in which the films are left and one in which the films are removed, the film removal step and the sorting step are repeatedly carried out while serially heating the sorted material to be treated in which the films are left to the range of highest softening temperature or less of the films and the substrates of the coated resin products.
