A method and apparatus for individually collecting layers from a laminated film containing many layers made of different materials by peeling or separating the layers one from the other. The laminated film having a plurality of layers made of different materials is shredded into a plurality of fragments to be processed; and the fragments to be processed are peeled or separated according to the type of layer by applying an impact frictional striking force to each of the fragments to be processed. Subsequently, the peeled or separated layers obtained in the peeling and separating step are subjected to a wind force classifying step. The collected layers in the mixed state are separated from one another, and they are individually collected.
