cushioning packaging box

Abstract

A cushioning packaging box includes an integrally formed sheet material, which comprises a base plate, a first covering portion, and a second covering portion. The first covering portion has a first side plate, a first top plate, a folding plate, and a connecting plate. The first side plate has an insertion hole, and the connecting plate has a locking groove. The second covering portion has a second side plate and a second top plate, and the second top plate has an insertion piece. The sheet material is bent to form a box body, the locking grooves interlock, and the insertion piece is inserted into the insertion hole. This creates a receiving space above the base plate for separating and positioning a pre-set container and a pre-set tray, thus achieving the cushioning packaging box structure.
