    摘要: A sheet manufacturing apparatus includes: a defibrating unit which defibrates a defibration object including fibers; a cylinder unit which allows a defibrated material which is defibration-processed in the defibrating unit and introduced via an introduction port to pass through a plurality of holes that is on a cylindrical surface by rotating; a supplying unit which is provided with a supply port which supplies additive agents that bond the plurality of fibers in the cylinder portion; and a bonding unit which forms a sheet by bonding the fibers and the additive agents.

    摘要: The invention relates to a supercalendered Kraft paper production for a release liner, which contains both non-recycled bleached chemical pulps and recycled pulp produced from release liner supercalendered Kraft paper. When highly specific raw material is used for recycling, the characteristics of the recycled pulp may be adjusted already upon recycling. The recycled pulp obtained from supercalendered Kraft paper that has been used as a substrate of a release liner may be used without further refining for manufacturing supercalendered Kraft paper. Excessive refining can thus be avoided and the compatibility of the recycled pulp may be optimized for supercalendered Kraft paper production. The non-recycled pulps may be refined less, as well. This leads to positive effects in supercalendered Kraft paper manufacturing process, such as improved dewatering and energy efficient drying. The produced paper demonstrates reduced shrinkage and improved dimensional stability, while maintaining sufficient quality for use as a substrate for a release liner. A supercalendered Kraft paper with improved sustainability is produced.
