Abstract

The work aims to design a new kind of corrugated board with laminated structure, to solve the problems of poor repeated impact resistance of traditional corrugated board and obtain a new corrugated board with improved cushioning and damping performance for packaging. Firstly, the corrugating medium structure of the new corrugated board was designed. Secondly, the parameters of the new corrugated board and the traditional corrugated board were set, and the samples were made manually. Finally, the dynamic cushioning performance test and random vibration test were carried out to the two kinds of corrugated boards, and the performance of the two corrugated boards was compared and analyzed. The dynamic cushioning test showed that the cushioning performance of the new corrugated board was better than that of the traditional one under varied drop heights. Under repeated impact, the cumulative cushioning performance of the new corrugated board was also better than that of the traditional one. The random vibration test proved that the damping range of the new corrugated board was 63.4~200 Hz, while the traditional one had no damping performance in the range of 5~200 Hz. The vibration transitivity of the new corrugated board reached a peak value of 4.2 at about 40 Hz. At the natural frequency of 163 Hz of the traditional corrugated board, the elastic modulus of the new corrugated board was relatively small. The resonance frequency of 40 Hz should be avoided when the new corrugated board was used in the packaging design for highway and railway transportation. Compared with the traditional corrugated board, the dynamic cushioning performance and vibration damping performance of the proposed corrugated board are improved.
