Bonding aging resistance refers to the long-term stability of inter-fiber and inter-layer bonding force after paper production, a key indicator that determines the shelf life of composite paper and high-grade packaging paper. With the extension of storage time, affected by temperature and humidity alternation and micro-air oxidation, the internal bonding points of ordinary paper will gradually age and fail, resulting in slow decline of bonding fastness. Aged paper is prone to invisible delamination, edge peeling and interlayer separation during later processing and use. Different from instantaneous bonding strength, bonding aging performance focuses on long-term durability. Many paper products have qualified bonding strength when leaving the factory, but suffer from serious bonding failure after 3 to 6 months of storage, leading to customer complaints and return orders. Traditional bonding agents only improve initial bonding effect and lack anti-aging protection ability, and the bonding structure is easy to relax and fail over time. Shandong Ludao Energy Technology Co., Ltd. launches paper bonding anti-aging optimization solutions. By building aging-resistant stable bonding bridges between fibers, we enhance the anti-relaxation and anti-oxidation ability of bonding points. The technology locks long-term interlayer bonding fastness, avoids delayed delamination and peeling defects, ensures consistent processing performance of long-storage paper, and improves product after-sales quality stability and brand credibility.
