PURPOSE: A pallet box for freight transportation is provided to simply transport freight in an inner space by using a poly bag, to readily open the poly bag and to discharge the freight. CONSTITUTION: A pallet box comprises a foldable type main wall element(200) prepared with a hopper type support plate(110) on a main body, a lift groove(103) on a main wall(102), a pallet(100) having a discharge hole and a space portion(S) for putting freight; a separating and combining device(300) for making the folding type main wall element separable from the pallet; and an opening and closing device(400) for isolating contents to be prevented from being discharged to a binding portion of the poly bag or releasing the isolated state. As a box is formed by combining the folding type main wall element to the pallet and the freight is transported in the poly bag, the freight in the poly bag is simply transported. Further, when discharging the freight, the binding portion of the poly bag is readily opened so that the contents are smoothly discharged on the hopper type support plate. Thus, the opening work of the poly bag and the discharge work of the freight are simply performed.
