Calendering is the final, critical finishing step in the papermaking process that determines the surface properties and commercial value of the finished paper. After the dried paper web passes through the roll stack of a calender, the surface fibers are flattened and plasticized; this significantly enhances the paper’s smoothness and gloss while improving its density and thickness uniformity.

This calender enhances the paper surface by improving smoothness, gloss, and density; it minimizes cross-machine direction (CD) thickness variations through the use of zone-controlled (locally heated or cooled) rolls; additionally, calendering increases the paper’s breaking length. Based on factors such as the specific paper grade (e.g., fine paper, packaging paper, specialty paper), machine speed, web width, and surface finish requirements, Leizhan assists customers in selecting the most suitable calender type and configuration, ensuring an optimal balance between finishing quality and production costs.
