This article studies the influence of preparation process on the surface sizing performance of containerboard during enzymatic starch preparation.Enzymatic starch was prepared and used for surface sizing by changing process parameters such as enzyme dosage,gelatinization temperature,gelatinization concentration and starch dosage.Through measuring the physical properties of paper,this research aims to explore the optimal preparation process.The results showed that the paper had the best physical properties when the enzyme dosage was 4.56u/g,the gelatinization temperature was 85℃,the gelatinization time was 30 minutes,and the starch sizing amount was 3g/m2.
