| Shandong Ludao: Improve Low-Temp Folding Resistance |
Low-temperature folding resistance is a key adaptive indicator for paper products used in northern regions, cold chain logistics and low-temperature storage environments. Under low-temperature conditions, paper fibers are prone to rigidity and embrittlement, resulting in sharply reduced folding endurance. Ordinary paper will crack and break easily after folding in cold environments, causing packaging box damage, label fracture and product scrapping, which cannot meet the long-distance cold chain transportation and low-temperature storage needs of commodities. Most existing paper toughening technologies only work at normal temperature and cannot solve the problem of low-temperature brittleness. Shandong Ludao Energy Technology Co., Ltd. provides targeted low-temperature folding resistance optimization solutions. By adding low-temperature flexible protective components and optimizing fiber low-temperature activity, we improve the cold resistance of paper fibers, maintain excellent flexibility and folding toughness under low-temperature environments, and avoid folding cracking and brittle breakage. The solution adapts to all kinds of cold-chain packaging paper, logistics label paper and outdoor paper products, effectively expands the low-temperature application scenarios of paper, and creates differentiated market competitive advantages for enterprises. |
