Packaging box and display module packaging composition

The utility model discloses a packaging box and a display module packaging composition.The packaging box comprises a plurality of box plates, the multiple box plates are connected to define a containing cavity, at least two stress ribs protruding relative to the box plates are arranged on the outer side of at least one box plate, and receding grooves are formed between the adjacent stress ribs; limiting grooves are formed in the positions, corresponding to the receding grooves, of the inner sides of the box plates, and the orthographic projection of the receding grooves on the box plates covers the orthographic projection of the limiting grooves on the box plates. The packaging box is divided into a first box body and a second box body, the first box body is provided with a first opening end, the second box body is provided with a second opening end, and the first box body and the second box body are oppositely clamped through the first opening end and the second opening end so that a containing cavity can be formed in the first box body and the second box body. When the box plate is subjected to external force, the external force acts on the stress ribs and avoids products located in the limiting grooves, the situation that the products are damaged due to impact of the external force is avoided, the storage and transportation safety of the products is improved, and economic losses are avoided.
