Objective To study and obtain the damping and sealing results of a packaging box. Methods Based on design of a packaging box, vibration dampers shock test was conducted. To get accurate leak rate, a temperature and atmospheric pressure compensation model was established. Results The results showed that the damping effect was not less than 62. 3% . The air tightness test indicated that the leak rate of packaging box was 3. 03 X10^-4Pa·m³/ s. Conclusion These results provide the basis for packaging box design typification, and give the experimental basis and reference for other damping or sealing packaging box.
