The utility model relates to a backpressure floating sealing strip for a scroll air compressor, and belongs to the technical field of scroll air compressors. The top surface of the sealing strip body is a plane friction surface, and the bottom surface of the sealing strip body is a zigzag back pressure surface; the sealing strip body is divided into a sealing strip center section and a sealing strip periphery section, the starting end of the sealing strip center section and the starting end of the sealing strip periphery section serve as sawtooth tooth roots, and sawteeth are arranged from inside to outside. Due to the design of the zigzag back pressure surface, high-pressure gas can enter the sealing strip from the back of the sealing strip, the sealing strip is tightly attached to a scroll plate through gas pressure difference, the back pressure floating performance of the sealing strip of the scroll type air compressor is improved, axial flexible compensation is achieved, gas leakage of each compression ca
