[0002] In the field of circulation of high-end industrial products, the transportation and packaging system of precision instruments, medical equipment and high-value-added products is facing more stringent physical protection requirements. Combined with the whole cycle tracking data of logistics, the current corrugated carton generally has insufficient performance redundancy in key indicators such as compression strength, dynamic impact absorption and breakage resistance. The root cause is that the creep characteristics of the fiber material of the traditional three-layer / five-layer corrugated structure lead to an exponential decay of the stiffness of the box body when dealing with high-frequency stacking, mechanical loading and unloading impact and extreme temperature and humidity environment in multimodal transport.

[0003] Therefore, there is an urgent need for a corrugated carton that meets higher requirements for compression resistance, breakage resistance and impact resistance. SUMMARY
