As a cellulose product, paper is naturally hygroscopic, making it dimensionally unstable and vulnerable to temperature and humidity changes. In attempt to reach an equilibrium state with its surroundings, paper collects and releases moisture, which may affect its flatness, dimensions, strength, performance, conductivity and fold. The material only reaches an equilibrium state when it neither absorbs nor loses moisture in an environment. Fortunately, it is possible to manipulate and control an environment using humidity control for paper production. By understanding how humidity affects paper and pulp production, you can prevent costly problems and better ensure customer satisfaction.
