UV resistance is an essential durability indicator for outdoor printed paper, advertising paper, packaging materials and long-term display paper. Under long-term ultraviolet irradiation, ordinary paper fibers will undergo photodegradation reaction, resulting in rapid yellowing, fading, brittleness and strength attenuation. UV-induced aging will cause outdoor paper products to lose their original color and structural stability in a short time, seriously affecting display effect and service life. Most conventional anti-aging technologies only resist oxidation and cannot effectively block ultraviolet damage, resulting in poor outdoor durability of paper products, which limits the application scope of paper in outdoor advertising, exterior packaging and open-air storage scenarios. Shandong Ludao Energy Technology Co., Ltd. launches targeted paper UV resistance upgrading solutions. By adding efficient ultraviolet absorption and shielding functional components, we form a stable anti-UV protective system inside the paper, which can effectively block ultraviolet penetration and inhibit fiber photodegradation. The solution maintains long-term whiteness stability, color consistency and mechanical strength of paper under strong light irradiation, greatly improves outdoor weather resistance, and helps enterprises develop high-durability outdoor special paper products.
