A part of corn starch in corrugating medium surface sizing was replaced with magnesium nitrate magnesium chloride or magnesium sulfate the influence of addition of the inorganic salts on corrugating medium physical strength and other properties was discussed. The results showed that when the mass ratio of starch to inorganic salt was 8 2 compared with the corrugating medium before surface sizing cross direction ring crush indexes increased by 76. 3% 80. 0% 82. 5% machine direction ring crush indexes increased by 74. 7% 72. 6% 80. 9% burst indexes increased by 13. 1% 14. 3% 15. 6% when magnesium nitrate magnesium chloride and magnesium sulfate were replaced a part of corn starch respectively. Adding grafted starch surface sizing agent cobb value of paper dropped from 140 g /m 2 to 30 g /m 2 which met the requirements of moisture proof.
