A two-handle packaging structure, comprising:

• a bottom comprising a plurality of fitting holes, the fitting holes being disposed at two opposite sides of the bottom;
• two foldable areas connected to the other two opposite sides of the bottom, each of the foldable areas and the bottom respectively having a first fold line therebetween;
• two first supporting portions connected to two opposite sides of one of the two foldable areas, each of the one of the two foldable areas and each of the first supporting portions respectively having a second fold line therebetween;
• two second supporting portions connected to two opposite sides of the other one of the two foldable areas, each of the other one of the two foldable areas and each of the second supporting portions respectively having a third fold line therebetween;
• two third supporting portions connected to the two opposite sides of the bottom, each of the third supporting portions and the bottom respectively having a fourth fold line therebetween;
• two rib portions, each rib portion comprising a hole, each rib portion being connected to each of the third supporting portions, and each rib portion and each of the third supporting portions respectively having a fifth fold line therebetween;
• two fourth supporting portions comprising a plurality of protruding portions, each of the fourth supporting portions being connected to each of the rib portions, such that each of the fourth supporting portions and each of the third supporting portions are respectively disposed at two opposite sides of each of the rib portions, and each of the fourth supporting portions and each of the rib portions respectively having a sixth fold line therebetween;
• and
• two handles, each handle being connected to each of the second supporting portions;
• wherein, when the two-handle packaging structure is folded along the two first fold lines, the two second fold lines, the two third fold lines, the two fourth fold lines, the two fifth fold lines and the two sixth fold lines, each of the first supporting portions and each of the second supporting portions are clamped by the corresponding third supporting portions and the corresponding fourth supporting portions, the protruding portions of each of the fourth supporting portions are correspondingly engaged with the fitting holes of the bottom, and each of the handles extends through the hole of each rib portion.
