According to the relation between external structure and internal structure, there are two design modes in structure design of paper package: split design, and integrated design. Through analyzing of examples of inkstone packages, we compared from the computation of compressive strength of empty boxes, computation of stacking capacity, and use of materials and molding process respectively. We concluded that integrated design in structure design of paper box has obvious advantage and development space, and it is a rational thinking in accordance with green package design and sustainable development.
