| Abstract: |
| Corn starch was modified by α-amylase，and the modified starch was applied to surface sizing of kraft paper board to improve its stiffness． The penetration of starch in paper board was studied． The modified starch with viscosity of 75 mPa·s was applied to surface sizing of kraft paper board．Under the condition of sizing solution concentration 12%，sizing temperature 70℃ and sizing amount 8 g/m2，the ring crush index and stiffness index increased respectively to 11.51 N·m/g and 232.6 N·m3/g． The image analysis of the paper board cross-sections indicated that starch with low viscosity could penetrate into internal paper board by surface sizing at low solids contents．Present study confirmed that starch distributed evenly in z-direction of the paper board by surface sizing using the starch with viscosity 75 mPa·s at 12% solids content． |
