300 million tonnes of plastic waste are produced annually. This is a global challenge and 170 nations pledged to significantly reduce plastic use by 2030. New regulations and consumer behavior are making sustainable packaging (compostable and fully-recyclable) necessary in the food industry, but sustainable packaging does not provide an adequate barrier to the water and oxygen that cause food to spoil. Consumer-packaged-goods companies, and the film producers and packaging converters that supply their packaging materials, need barrier solutions to transition to sustainable packaging without increasing food waste and compromising food safety. The project team has developed atmospheric-pressure spatial atomic layer deposition (AP-SALD) technology for high-throughput coating of barriers on packaging materials, which is being commercialized by Nfinite Nanotechnology Inc. Compared to traditional barrier coatings, AP-SALD metal-oxide coatings are only a few tens of nanometers (billionths of a meter) thick, so they do not affect the compostability or recyclability of sustainable packaging, and they are free of pinholes so they provide superior barrier properties. Compared to traditional manufacturing methods, AP-SALD is solvent-free and open-air, so it is cheaper, faster, and green. In this project, the research team and Nfinite will optimize their novel AP-SALD barrier coatings on different sustainable packaging materials, transfer the technology to a roll-to-roll coating process, and develop an additional coating material for the sustainable packaging industry.The project will address remaining commercialization barriers, enabling Nfinite to sell their AP-SALD equipment to the packaging industry. The project will foster the growth of an innovative startup company and bring significant economic and environmental benefits to Canada. The technology will simultaneously reduce plastic waste, food waste, and associated greenhouse gas emissions.

每年产生3亿吨塑料垃圾。这是一个全球性的挑战，170个国家承诺到2030年大幅减少塑料的使用。新的法规和消费者行为使得可持续包装（可堆肥和完全可回收）在食品行业中成为必要，但可持续包装并不能为导致食品变质的水和氧气提供足够的屏障。消费品包装公司以及提供包装材料的薄膜生产商和包装加工商需要屏障解决方案，以过渡到可持续包装，而不会增加食品浪费和影响食品安全。该项目团队开发了大气压空间原子层沉积（AP-SALD）技术，用于包装材料上的高通量屏障涂层，该技术正在由Nfinite Nanotechnology Inc.商业化。与传统的阻隔涂层相比，AP-SALD金属氧化物涂层只有几十纳米（十亿分之一米）厚，因此不会影响可持续包装的可堆肥性或可回收性，并且没有针孔，因此具有上级阻隔性能。与传统的制造方法相比，AP-SALD是无溶剂和露天的，因此它更便宜，更快，更绿色。在该项目中，研究团队和Nfinite将优化他们在不同可持续包装材料上的新型AP-SALD阻隔涂层，将该技术转移到卷对卷涂布工艺中，并为可持续包装行业开发额外的涂层材料。该项目将解决剩余的商业化障碍，使Nfinite能够将其AP-SALD设备销售给包装行业。该项目将促进创新创业公司的发展，并为加拿大带来重大的经济和环境效益。该技术将同时减少塑料垃圾，食物垃圾和相关的温室气体排放。
