Disposable and compostable paper plates from the Royal Chinet brand are world famous. Although they areavailable in several sizes from 6.75 to 12 inches, it is the size 8½ inches which is the most sold by CKF Inc. Inorder to offer its customers even more efficient products, CKF would like to assess the potential of a new typeof raw material. In this project, CKF answers the market demand for strong and lightweight ecological dinnerplates, by developing and optimizing a Bleached Chemi-Thermo-Mechanical Pulp (BCTMP) recipe. Thisrecipe is expected to increase the rigidity (stiffness) of CKF's 8½-inch diameter dinner plate, whiledemonstrating attractive surface properties and productive manufacturing parameters on industrial scale pulpthermoforming process. The project will have to demonstrate, from a process point of view, a profitable use ofthis Canadian raw material. The characteristics of this pulp will influence formation time, drainage, drying oreven the print quality of the plates, which wil have a significant influence on the process performance.

Royal Chinet 品牌的一次性和可堆肥纸盘享誉世界。虽然它们有 6.75 至 12 英寸等多种尺寸可供选择，但 CKF Inc. 销售最多的是 8.5 英寸尺寸。为了向客户提供更高效的产品，CKF 希望评估新型原材料的潜力。在该项目中，CKF 通过开发和优化漂白化学热机械纸浆 (BCTMP) 配方，满足市场对坚固、轻质生态餐盘的需求。该配方预计将提高 CKF 8.5 英寸直径餐盘的刚度（刚度），同时在工业规模纸浆热成型工艺中展示有吸引力的表面特性和生产制造参数。该项目必须从流程的角度证明这种加拿大原材料的利用是有利可图的。这种纸浆的特性会影响版材的形成时间、滤水、干燥甚至印刷质量，从而对工艺性能产生重大影响。
