ABSTRACT / SAŽETAK:
The paper and cardboard industry is one of the most energy-intensive manufacturing sectors, where environmental conditions significantly affect product quality, process stability, and energy consumption. Due to the hygroscopic nature of cellulose fibers, paper continuously exchanges moisture with the surrounding air, making relative humidity a critical process parameter. Inadequate humidity control may lead to dimensional instability, sheet deformation, static electricity generation, printing defects, increased waste, and reduced productivity. This paper presents the principles of humidity control in the paper industry, discusses the influence of humidity on paper properties, analyzes available humidification and dehumidification technologies, and highlights the relationship between humidity regulation and energy efficiency. Industrial examples and best practices are also presented to demonstrate the benefits of optimized humidity control systems.
