Impact resistance is a special mechanical performance that differs from conventional tensile and bursting strength, focusing on paper’s ability to resist instantaneous shock and collision damage. In logistics transportation, automated sorting and mechanical handling processes, paper packaging and sheet products often suffer instantaneous impact force from falling, collision and rapid stacking. Ordinary paper has weak instantaneous impact buffering capacity, and the fiber structure cannot absorb shock energy effectively, resulting in sudden local cracking, corner breakage and sheet fracture under strong instant impact. This kind of damage is different from slow extrusion deformation, featuring random occurrence and high batch loss rate, which greatly increases packaging cargo damage rate and finished product scrapping rate. Most traditional papermaking strengthening technologies only improve static strength indicators and cannot enhance dynamic impact energy absorption capacity. Simply increasing paper grammage raises costs significantly and still fails to solve brittle fracture under instantaneous shock. Shandong Ludao Energy Technology Co., Ltd. launches professional paper impact resistance upgrading solutions. By building a flexible energy-absorbing fiber cross-linking structure inside the paper, the system effectively disperses and absorbs instantaneous impact energy, avoids concentrated structural stress and sudden cracking. The optimized paper maintains lightweight characteristics while obtaining excellent dynamic shock resistance, effectively resists collision and falling damage during transportation and mechanical processing, improves packaging protection performance, and reduces enterprise logistics loss and defective rate.
