Weather resistance is an essential core indicator for outdoor packaging paper, construction protective paper and open-air logistics paper. In complex outdoor environments such as alternating temperature and humidity, wind and sun exposure, and seasonal rain and dew erosion, ordinary paper is prone to rapid aging, strength attenuation, surface cracking, discoloration and mildew. Poor weather resistance leads to short outdoor service life of paper products, easy damage of open-air packaging and failure of building protection. Conventional waterproof and anti-mold treatments only adapt to single humid environment and cannot resist composite weathering damage such as solar radiation, temperature difference alternating erosion and wind abrasion. After short-term outdoor exposure, the protective layer fails quickly, resulting in comprehensive performance degradation of paper. Shandong Ludao Energy Technology Co., Ltd. develops multi-effect paper weather resistance upgrading solutions. By compounding anti-ultraviolet, anti-aging and temperature and humidity alternating protective components, we build an all-weather stable protective structure on the paper surface and inside. The modified paper resists sun exposure, wind erosion and seasonal temperature and humidity changes, maintains stable strength, flatness and appearance, greatly extends outdoor service life, and meets the long-term protection requirements of outdoor engineering and open-air logistics scenarios.
