The invention provides a package structure which comprises a box body and a bottom plate. The bottom plate covers the bottom of the box body. A first side plate and a third side plate are made of spliced plate bodies correspondingly. Each spliced plate body comprises a first plate body and a second plate body, wherein the first plate body and the second plate body are connected through a connecting component. Fixing wing plates are arranged on the two sides of the bottom plate in an extending manner. The fixing wing plates can be turned over and detachably connected with any two or more of thefirst side plate, a second side plate, the third side plate and a fourth side plate. According to the package structure, the first side plate and the third side plate are each divided into the firstplate body and the second plate body, each first plate body and the corresponding second plate body can be rotated and folded through the connecting component, each first plate body and the corresponding second plate body can be mutually attached in the folding process, the second side plate and the fourth side plate can be mutually attached in the folding process, the bottom plate is folded towards the box body through the fixing wing plates on the two sides, thus the bottom plate and the box body are connected, and after folding, the occupied size and the thickness are small.
