The paper folding endurance tester is used to measure the number of folds and folding endurance of paper. It is suitable for the ability of box board paper, kraft paper, cardboard, corrugated paper, gray board paper and other paper to resist folding fatigue. It is also suitable for measuring the folding fatigue strength of other sheet materials with a thickness of less than 1mm (such as copper foil in the electronics industry). By measuring, the requirements for controlling the physical properties of materials are achieved to meet the practical application needs of the product.
