The invention provides a bottle label sorting system which comprises a conveying line used for conveying labels to be sorted; the thermal shrinkage module is arranged above the conveying line and used for heating the labels to be sorted on the conveying line to be in a thermal shrinkage state; the spectrum recognition module is arranged on one side of the conveying line and used for recognizing the labels in the thermal shrinkage state on the conveying line; the sorting module is arranged on one side of the conveying line, electrically connected with the spectrum recognition module and used for sorting labels according to the recognition result of the spectrum recognition module. According to the method, the waste labels are subjected to heat treatment to be in the state suitable for sorting, then spectrum recognition and sorting are conducted, polymer labels not suitable for sorting are treated to be in the state suitable for sorting, sorting of PP, PE, PET and PVC labels and PET/PE bottle chips mixed in the
