The invention relates to a coextrusion composite polypropylene soft pipe and a production method; the coextrusion composite polypropylene soft pipe comprises a pipe head and a pipe body, the pipe body is a composite structure with 2-5 layers, wherein at least one layer material is the polypropylene or the mixture of the polypropylene and polyethylene, the raw material of the polypropylene adopts 0.5-2.0g/10min of melt index and is random copolymerization polypropylene catalyzed by metallocene catalyst; the pipe body of the soft pipe is produced by adopting coextrusion process, especially, raw materials of all layers of the pipe body of the soft pipe are added in respective single screw extrusion machine from each hopper, and the materials are melted and are coextruded out from the same molding mixing machine, and then drawing, cooling, vacuum formation, heat treatment, traction, and fixed length cutting are carried out, so as to obtain the pipe body, and mature head injection, printing, post processing, packaging and other procedures are carried out to the pipe body, so as to obtain the composite polypropylene soft pipe finished product. The composite polypropylene soft pipe has high transparency and is harder than the existing product, and the whole weight of the soft pipe is reduced.
