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享誉世界。虽然它们有从6.75英寸到12英寸的几种尺寸可供选择，但8.5英寸是CKF公司卖得最多的。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，满足了市场对坚固和轻质生态餐盘的需求。该配方预计将增加CKF直径8.5英寸餐盘的硬度(刚性)，同时在工业规模纸浆热成型过程中展示诱人的表面特性和生产性制造参数。该项目必须从工艺的角度展示这种加拿大原材料的有利可图的使用。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，这将对印版的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.
