摘要： There is provided a method for peeling a coating from coated plastics, comprising applying a shear stress to a plastic product having a coating thereon, optionally after preforming the plastic product into a flat plate form, thereby to peel the coating from the plastic product. There is also provided an apparatus for peeling a coating from coated plastics, comprising a pair of rolls with a gap therebetween and driving means for rotating the pair of rolls, the rolls rotating at different peripheral speeds from each other and allowing a plastic body having a coating thereon to pass through the gap while applying a shear stress to the plastic body thereby to peel the coating from the plastic body. Further, there is provided a method for recycling plastics, comprising applying a shear stress to a plastic product having a coating thereon, optionally after preforming the plastic product into a flat plate form, thereby to peel the coating from the plastic product, and then subjecting the coat-peeled plastic product to melting and molding.
