摘要： A method and apparatus for making banded smoking article wrappers is provided. The apparatus includes a cylindrical rotating applicator that has alternating regions of mesh material and regions of solid material on its outside surface. The applicator allows repetitive patterns of additional slurry to be applied to a continuous web of paper so that the basis weight of the paper is repetitively increased. Such paper, when incorporated into a smoking article, modifies the burn rate characteristics of the article.

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.

摘要： The invention relates to drinking U-straws and more particularly to a paper for manufacturing drinking U-straws, which is environmental friendly, bio-degradable and is able to be formed in the shape of a bent straw with an accordion-like structure at the bend. The paper has high water resistance as well as high strength and elongation properties compatible with the intended use. In particular, the paper for forming a U-straw includes: •between 10 and 50 dry wt % of first fibers having a length of between 1.4 mm and 2.5 mm; •between 40 and 80 dry wt % of second fibers having a length of between 0.3 mm and 0.8 mm; and•between 1 and 6 dry wt % of a sizing agent.

摘要： A reusable, fiber containing pulp product is described that is highly suited for use in the manufacture of paper products. The reusable, fiber containing pulp product provides a mixture of fibers and small, dense polymer/particle fragments. The polymer/particle fragments within the reusable, fiber containing pulp product have a size range and density that facilitates efficient removal of the polymer/particle fragments using pressure screens.
