A pail pack for welding wire is provided to reinforce the strength by being made of paper materials that are compressed through press processing by use of a mold and to improve the re-utilization of the pail pack. A pail pack for welding wire includes an outer drum(10) in a cylindrical shape, a bottom plate(20) and a polygonal drum(30). The outer drum forms a body. The bottom plate is installed on the inner side of the lower end portion of the outer drum, and has a support potion(22) whose frame is formed to be bent in a lower direction to come into contact with the inner circumference of the lower end of the outer drum. The polygonal drum comes into contact with the outer drum, and has a polygonal section into which a winding layer of the welding wire(80) is received.
