24 pulping runs for producing corrugating medium were conducted with various chemical concentrations of sodium carbonate and sodium sulfide (green liquor). All other pulping variables were held constant. The results showed a linear relation between the amount of total alkali (on wood) and yield decrease at constant sulfidities. The results also showed the optimum sulfidity of the liquors to be 25%. The strength properties were only affected by the pulp yield and not by the amount of chemical concentration used to produce that yield.
