The proposed research will be undertaken by Dr. Yonghao Ni and his team at the Limerick Pulp and Paper Centre located at the University of New Brunswick (UNB), in partnership with OVAL International. The Canadian pulp and paper industry faces strong international competition. Development of high-value cellulose-based products will help Canadian pulp and paper companies to extract more value from forest resources and remain competitive in the international market. In this research, the overall goal is to develop cellulose fiber-based packaging products (paper straps) that can replace similar traditional non-recyclable/non-biodegradable products, e.g., metal wires and plastic straps. The world's demand for eco-friendly and cellulose fiber-based products fits well with this industry need. The results from the proposed project will be beneficial not only to OVAL International, but to other Canadian packaging companies, and Canadian market pulp producers as well. The proposed novel product will use nano-crystalline cellulose (NCC) and nano-fibrillated cellulose (NFC), which are derived from forest resources. Canada is emerging as a leader for both products. Therefore, the proposed research will allow the diversification of markets both in Canada and around the world, creating new demands for forest products themselves and economic opportunities for forest-product communities and forest product companies. Deliverables include: 1) Determination of the interactions of PVOH and pH-responsive polymers such as polyacrylic acid (PAA) and their effects on the water resistance of the paper strap coating; 2) Development of smart pH-responsive PVOH/PAA technology that can meet the high-moisture environmental demands of the paper strap manufacturing industry (for strapping market pulp bales containing up to 20% moisture); 3) Development of vitrimer-based technology to sustain the required heat sealability for wet pulp with up to 20% moisture content.

拟议的研究将由倪永浩博士和他的团队在新玩法大学（UNB）的利默里克纸浆和造纸中心与OVAL国际合作进行。加拿大纸浆和造纸业面临着强大的国际竞争。开发高价值的纤维素产品将有助于加拿大纸浆和造纸公司从森林资源中获得更多价值，并在国际市场上保持竞争力。在这项研究中，总体目标是开发基于纤维素纤维的包装产品（纸带），可以替代类似的传统不可回收/不可生物降解产品，例如，金属线和塑料带。世界对生态友好型纤维素纤维产品的需求很好地满足了这一行业需求。拟议项目的结果不仅对OVAL国际公司有利，而且对其他加拿大包装公司和加拿大市场纸浆生产商也有利。 拟议的新产品将使用来自森林资源的纳米结晶纤维素（NCC）和纳米原纤化纤维素（NFC）。加拿大正在成为这两种产品的领导者。因此，拟议的研究将使加拿大和世界各地的市场多样化，为森林产品本身创造新的需求，并为森林产品社区和森林产品公司创造经济机会。 可供选择的产品包括：1）测定PVOH和pH响应性聚合物如聚丙烯酸（PAA）的相互作用及其对纸带涂层的耐水性的影响; 2）开发可满足纸带制造行业的高湿度环境要求的智能pH响应性PVOH/PAA技术（用于捆扎含水量高达20%的市售纸浆包）; 3）开发基于硫酸盐的技术，以维持含水量高达20%的湿纸浆所需的热密封性。
