Opportunities and challenges for the use of starch in the production, coating, and conversion of paper are reviewed. In the U.S. paper industry, starch has to compete with many synthetic materials that often outperform starch in molecular design, charge adjustment, viscosity characteristics, and binding power. Commodity starches are often not sufficient to meet the requirements of modem papermaking operations. New challenges have developed as a result of the increasing closure of paper mill systems, which increased the presence of anionic trash and electrolytes, and from the installation of new equipment for high speed surface sizing and coating, which has led to higher demands on the rheological and water holding properties of the complex two‐phase coating systems now in use or under development. Opportunities for the continued or expanded use of starch will depend on close cooperation between individual paper companies and their starch suppliers. Graft co‐polymerization of starch may offer new application opportunities at competitive cost.
