The food packaging box is a square box and is divided into upper and lower two-story spaces. The upper space has an upper cover, the lower space has a pull-out drawer, and the drawer has a handle. A box jacket is arranged on the box body casing. The box jacket is unfolded into a long shape and is folded along the left and right sides of the box body through the buckles on the box. Since the food packaging box is a double-layered structure, its spacing is novel and the appearance is beautiful, which changes the boring structure of the traditional food packaging box and allows different kinds of foods to be placed. The box casing can also function as a packaging box body.
