Optimization of bending stiffness and out-of-plane strength of thermoformed pulp products

皇家Chinet品牌的一次性和可堆肥纸盘世界闻名。虽然它们有从6.75英寸到12英寸的几种尺寸可供选择，但CKF Inc.销售最多的是8½英寸的尺寸。为了向客户提供更高效的产品，CKF希望评估一种新型原材料的潜力。在这个项目中，CKF通过开发和优化漂白化学热机械浆（BCTMP）配方，满足了市场对坚固轻质生态餐盘的需求。该配方有望增加CKF 8½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性制造参数。该项目将不得不证明，从过程的角度来看，一个有利可图的使用这种加拿大原材料。这种纸浆的特性会影响印版的成型时间、滤水、干燥甚至印刷质量，从而对工艺性能产生重大影响。

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.
