Abstract: A binding box for packaging and paper recycling comprises of a base, four trays, and four supporting parts connecting the trays and base, respectively. Each of the trays holds a corner to a quarter of the area of the papers or materials which need to be bound. The four trays work together to hold papers or any materials that needs to be bound but there is a clearance between any two pairs of the trays. Given the clearance between the trays and the clearance between the base and trays, human hands, ropes, or binding tools can go through to bind the papers without touching any one of the trays or moving the objects which needs to be bound. The ropes are placed in the clearances between trays. Once the binding is finished, a stack of bound papers or materials can be removed directly from the top of the binding box without moving the box.
