Abstract

Starch is commonly used in the paper industry for a variety of applications, including coating. In coating, starch is used as a binder to hold coating pigments together and to hold coatings to the paper. Every type of starch has a different effect on characteristics such as runnability, optical, printing, and physical properties. Unmodified starch was converted using enzymes to prepare coatings. The coatings were applied to paper. Testing and evaluation followed to observe the effect that the different starches had on the overall properties of the sheet. The evaluation showed that wheat starch is the best overall starch. Its strongest points were runnability, optical properties, and cost. Potato starch followed with its strongest points being the physical and printing properties.
