PURPOSE: A packing method of a binder ring for document booklet and a structure thereof are provided to prevent deformation by preventing binder rings from being twisted in middle of transfer. CONSTITUTION: Binder rings(3) are inserted into a fork-shaped jig(5). The binder rings are fixed on the fixed film by welding one side of the binder rings on a polymer fixing film(6). The fixed binder rings remove the jig and are formed into a unit packing body. The unit packing bodies are laminated to fold the binder rings and are inserted into a package box.
