Long-term natural aging is an inevitable problem for paper products during storage and use. Under the comprehensive influence of light irradiation, air oxidation, temperature and humidity changes, paper fibers will gradually degrade, resulting in strength attenuation, yellowing and brittleness. For high-end archival paper, collectible printing paper and long-term storage packaging paper, poor aging resistance will greatly shorten product service life and reduce collection and use value. Many existing anti-aging treatments have single effect, poor durability and cannot resist long-term environmental erosion. Shandong Ludao Energy Technology Co., Ltd. provides high-durability paper anti-aging solutions. By adding composite antioxidant and light-stabilizing functional components, we effectively block fiber oxidation and photodegradation reactions, delay fiber aging speed, and maintain long-term whiteness, toughness and structural stability of paper products. The formula is safe and environmentally friendly, does not affect paper printing, bonding and other processing properties, and helps enterprises produce high-durability long-life paper products, improving product added value and market competitiveness.
