Standard Test Analysis of Edgewise Crush Resistance and Bursting Strength of Corrugated Board

Check whether the edgewise crush resistance and bursting strength specified in GB/T6544-2008 meet the two performance indexes of corrugated board produced by Yifeng Weiye Group, which provide the basis for the standard revision. Experiments were carried out to test the edgewise crush resistance and bursting strength of single and double corrugated board, and comparative analysis of these two performance indicators with standard superior products and qualified products. The results show that the proportion of samples with minimum comprehensive quantitative of corrugated board below the standard value is larger. Under the same weight, the edgewise crush resistance is higher than the standard superior products, and the bursting strength is basically between the standard superior products and qualified products. Corrugated board produced by Yifeng Weiye Group develops to low weight and high strength. The minimum comprehensive quantitative range of GB/T6544-2008 is narrow, and the performance indicators are low. Therefore, it is necessary to revise the GB/T6544-2008 to improve the quality of corrugated board.
