Abstract
This study was carried out to determine comparability of tearing resistance measured by dynamic and static testing devices. Tearing indices of double tear samples from different commercial paper grades were determined dynamically by using pendulum type Marx-Maller Elmendorf device and statically by using Zwick/Roell universal tensile testing device. Tear resistance values for dynamic and static tests were compared and good correlation was observed (R²-0.96 and 0.99 for MD and CD respectively). Tear index ratios (cross direction / machine direction) of the two methods was found to be relatively close for all paper grades. Force required for initiation of static tearing at machine direction was bigger than at cross direction and variate from 1 to 7 N for different paper grades.
