For the determination folding fatigue strength of the thickness of less than 1mm paper, cardboard and other sheet materials. Using MIT folding method. Color touch-screen display, folding fixture automatically return after each test, statistics of the same group of multiple samples of the data, the maximum, minimum, average and coefficient of variation.
Applications
Folding Endurance: Under specified conditions, the number of double folding that the test specimen can withstand before breaking indicates the ability of the test specimen to be repeatedly folded. This ability is necessary for sack paper and coin paper. It is also suitable for printing paper, drawing paper, Wrapping paper.
