Zusammenfassung:	The invention belongs to the technical field of dialysate medical packaging, and particularly relates to a novel ultra-clean high-barrier film bag for dialysate. The film bag is a five-layer co-extrusion film, and the inner layer is composed of metallocene polyethylene, high-pressure polyethylene and high-density polyethylene; the secondary inner layer is an adhesive; the middle layer is an ethylene/vinyl alcohol copolymer; the secondary outer layer is an adhesive; and the outer layer consists of linear polyethylene, high-pressure polyethylene and high-density polyethylene. The novel ultra-clean high-barrier film bag for dialysate is convenient to use, capable of being produced in a clean area, free of washing, capable of being used immediately, safer and capable of avoiding secondary pollution and cross infection, and compared with a three-layer co-extrusion film, the five-layer co-extrusion film has better flexibility and mechanical strength and has the effects of being ultra-clean,high in barrier, low in c
