Cushioning packaging design software was developed by using graphic programming LabVIEW based on the theory, model equation, and experimental data of constitutive equation of foamed material. The software can automatically calculate cushioning area and thickness for cushioning design. The cushioning packaging database was established based on experiments and calculation. The users can design the packaging with different materials and density by calling the corresponded data in the database. An extended function of the database was added, where users can add their own testing data of certain packaging materials, and expand materials in the database. By inputting cushioning material, product basic information, the software can automatically calculate the target, which can help engineers without testing conditions, and greatly improve the design efficiency.
