The results of determination of mechanical indices of two-layered paperboard by measuring the length of contacts of fibers in the transverse section are presented. The developed technique of getting transverse section of paperboard and evaluations by graphical and computational programs made it possible to determine the total length of contact lines, uniformity of distribution of contact lines by size, and uniformity of their distribution over the area of the transverse section of the paperboard. These parameters characterize the interfiber forces of bonding in the paperboard and, consequently, its mechanical properties.
