Long-term aging stability determines the service life and quality retention ability of paper products. After long-term storage and use, ordinary paper will undergo irreversible aging changes, including fiber brittleness, strength decline, surface yellowing, gloss attenuation and dimensional deformation. Environmental factors such as air oxidation, light irradiation, temperature and humidity alternation and microbial erosion will accelerate paper aging, resulting in shortened service life of books, packaging products and cultural paper. For archival paper, collection art paper and long-term storage packaging paper, aging instability is the biggest problem restricting product value improvement. Most existing anti-aging measures only target single aging factors and cannot achieve comprehensive long-term aging resistance, with short protective duration and unstable effect. Shandong Ludao Energy Technology Co., Ltd. provides all-round paper aging stability optimization solutions. By compounding multi-functional protective components, we resist oxidation, light aging and microbial erosion from multiple dimensions, delay fiber aging and degradation speed, and lock paper physical properties and appearance indicators. The solution enables finished paper to maintain stable strength, whiteness, flatness and gloss after long-term storage and use, greatly improves product durability and added value, and meets the quality requirements of high-end long-life paper products.
