A multifunctional packing box comprises a box body provided with an accommodating cavity, and a lid body covering the accommodating cavity of the box body, wherein the box body comprises lateral walls and a bottom wall; the lid body is moveably connected with the lateral walls of the box body; both the lid body and the lateral walls of the box body comprise a rigid base plate and a leather layer, with which the base plate is coated; and at least two leather layers are arranged at the connecting part of the lid body and the lateral walls of the box body. Since the lid body and the lateral walls of the box body are connected by the leather layers with high flexibility, the number of times of opening and closing the lid body can be double increased, and the service life of the entire packing box can be double prolonged.
