The paper and paperboard packaging market is actually subjected to a strong and growing trend from consumerpreferences towards biodegradable materials due to environmental concerns. As a matter of fact, there is a fastgrowing need for sustainable, cost-effective, and ecologically compatible high-barrier materials as areplacement for petroleum derived polymers for food packaging and other applications that contribute to land and ocean pollution. Packaging trends are actually moving from synthetic, non-recyclable materials tosustainable, recyclable, compostable and repulpable natural materials. Moreover, increasing cost of nonbio-based options is an issue. Therefore, there is an interest to replace fossil-based polymers by biopolymers in such packaging applications. Paper packaging materials should provide the necessary barrier properties against water, water vapor, gases/air and grease/oils depending on end-use applications. New technologies must bedeveloped not only to improve barrier properties but also to comply with sustainability issues. This research project is aiming at the development of packaging products using bio-based polymers. Coating formulations will be developed and applied on paper from laboratory coater to pilot coater. This research is important for theindustrial partner allowing him to develop new competitive products for fast growing markets. This projectshould globally; contribute to sustainability and environmental accountability by a better use of one of Canada'smost abundant, renewable resources, its forests; provide the consumer markets with eco-friendly packagingproducts containing recyclable and re-usable fibers and bio-derived polymers for replacement ofpetroleum-based plastics, and finally; contribute to find partial solutions to waste-disposal problems associated with traditional petroleum-derived packaging materials.

由于环境问题，消费者对可生物降解材料的偏好实际上使纸和纸板包装市场呈现出强劲且增长的趋势。事实上，对可持续、经济有效且生态兼容的高阻隔材料的需求正在快速增长，以替代石油衍生聚合物用于食品包装和其他造成陆地和海洋污染的应用。包装趋势实际上正在从合成的、不可回收的材料转向可持续的、可回收的、可堆肥的和可再制浆的天然材料。此外，非生物基选项的成本增加也是一个问题。因此，在此类包装应用中，人们有兴趣用生物聚合物代替化石基聚合物。根据最终用途，纸包装材料应提供必要的水、水蒸气、气体/空气和油脂/油的阻隔性能。必须开发新技术，不仅要提高阻隔性能，还要满足可持续性问题。该研究项目旨在开发使用生物基聚合物的包装产品。涂料配方将被开发并应用于从实验室涂布机到中试涂布机的纸张上。这项研究对于工业合作伙伴来说非常重要，使他能够为快速增长的市场开发新的有竞争力的产品。该项目应该是全球性的；通过更好地利用加拿大最丰富的可再生资源之一——森林，为可持续发展和环境责任做出贡献；为消费市场提供含有可回收和可重复使用的纤维和生物衍生聚合物的环保包装产品，以替代石油基塑料；有助于找到与传统石油衍生包装材料相关的废物处理问题的部分解决方案。
