ABSTRACT:
A packing paper box with a moisture resistant band having a function to prevent a content from being leaked out of the paper box even when the paper box is partially deformed due to a careless handling during transportation or storage thereof. The moisture resistant band has a strip shape and is attached to junctions between the upper edges of vertical wall members of the paper box and the upper flap members of the paper box and between the lower edges of the vertical wall members and the lower flap members of the paper box. The moisture resistant band has a predetermined width and serves to sufficiently seal corners of the paper box upon folding the flap members. By virtue of the moisture resistant band, the packing paper box has a simple construction capable of providing both a moisture resistance and a durability.
