When C-CTMP mass ratio was 40% ,the produced corrugated paper exhibited a density of 0.62g/cm3 ,breaking length of 4.25km,and ring crush index of 8.24 N·m/g ,all demonstrating favorable mechanical performance.Furthermore,with the addition of 0.25% alkyl ketene dimer (AKD) and 1% (204号 dry cationic starch (both based on oven-dry pulp mass),the corrugated paper achieved a density of 0.60g/cms ,breaking length of 4.56 km,ring crush index of 8.62 N·m/g ,and water absorption Cobb60 value of 13.00g/m2 ,meeting the requirements for Grade AAA premium products under GB/T 13023—2008.
