Elmendorf Tearing Tester (Digital Display Type)

This machine is designed to measure the resistance to tearing of various kinds of printing paper such as newspaper, paper bags, packing paper, when subject to tearing stress during their use. Usually, tear resistance is composed of force of extracting fibers from paper layers and force of cutting the fibers. In general, the longer the fiber length is, the stronger tear resistance is. When the binding area among fibers increases, exceeding the optimal area, the tear strength decreases inversely with the trends of tensile and bursting strengths. This machine with an additional weight on (option) can measure a wide range of materials, including paper, paperboard, fibers, plastic film, and the like. With a pneumatic specimen clamp, the system is excellent in operation, displaying an average measurement for a unit of 16 sheets.
