The machine is used to detect the burst strength and burst index of paper and cardboard. It is to detect the ability of the carton to protect the product during handling, loading and unloading, impact, tearing and extrusion during the circulation process. It is the comprehensive performance of the carton. one of the evaluation methods. Suitable for box board, kraft paper, cardboard, corrugated paper, gray board paper, etc. It is more suitable for carton manufacturers, carton users, scientific research institutions and so on.
