Tear uniformity is a key mechanical index that determines the safety and neatness of paper tearing and opening performance. Many packaging paper and industrial paper have obvious directional tear difference, showing easy tearing in one direction and tough tearing in the other direction, accompanied by irregular tearing edges, fiber pulling and hole damage. Uneven longitudinal and transverse tear resistance leads to messy opening edges of daily packaging cartons, difficult manual tearing, and easy damage to internal goods during forced opening. For easy-tear packaging paper and special industrial split paper, tear uniformity directly determines product use experience and functional qualification rate. The root cause of uneven tear performance lies in directional fiber arrangement difference and unbalanced transverse and longitudinal bonding force. Traditional strengthening and softening treatments only change single-direction strength and cannot realize omni-directional tear balance. Shandong Ludao Energy Technology Co., Ltd. provides professional tear uniformity optimization solutions. By adjusting fiber directional arrangement structure and balancing transverse and longitudinal inter-fiber binding force, we realize consistent tear resistance in all directions. The treated paper has neat and flat tearing fracture, no fiber pulling and irregular edge damage, stable and controllable tear strength, improves easy-tear packaging use experience, and meets the precise splitting requirements of industrial special paper.
