Folding box

The invention discloses a folding box. The folding box comprises a base and two pairs of opposite side plates; a protecting edge is arranged at the outer periphery of the base; and the side plates are hinged to the base, and can be folded corresponding to the base. The side plates are double-glaze side plates; and cavities are formed in the lower edges of at least one pair of side plates. When the folding box is upright, the lower edges of one pair of side plates and the lower edges of the other pair of side plates are connected to form a frame; and the frame is hinged to the base through a hinge to form a reinforcing component for resisting sinking of the base and recessing of the protecting edge. The folding box can reduce the dirt residuals in repeated use to the greatest extent after cleaning, promotes the cleaning efficiency, improves sinking of the base after loading of a box body, solves the problem of collision damage between objects caused by sinking of the base due to pressing between upper and lower layers of goods when folding boxes are stacked by multiple layers, and solves the potential safety hazard of warehousing storage caused by stacking failure due to deformation of the side plates after pressing of the side plates due to stacking of multiple layers of boxes bodies when the boxes bodies are smaller in wall thickness and higher in folding rate.
