The effect of the addition of waste papers to the virgin kraft pulp upon the tensile properties, paper porosity, and bonding ability was investigated. Waste papers, namely postconsumer corrugated board (quality grade A5), and cutoffs obtained from never-used corrugated board (quality grade A6), were chosen as secondary fibers. The results obtained were evaluated using statistical methods and compared with those reported for sack papers. The addition of waste papers to virgin kraft pulp increased air resistance, but lowered tensile strength from 7.99 km for virgin kraft pulp to 3.83 and 4.13 km for waste paper of quality grades A5 and A6, respectively."@en .
