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.

每年生产3亿吨塑料废​​物。这是一个全球挑战，有170个国家承诺在2030年之前大大减少塑料的使用。新法规和消费者的行为使食品行业需要可持续包装（可堆肥和完全回收），但可持续包装并不能为范围提供足够的障碍。导致食物变质的水和氧气。消费者包装的商品公司以及提供包装材料的电影制作人和包装转换器需要障碍解决方案，以过渡到可持续包装，而不会增加食物浪费和损害食品安全。该项目团队已经开发了大气压空间原子层沉积（AP-SALD）技术，用于针对包装材料上屏障的高通量涂层，与传统的AP-SALD METAL-METAL-METAIL涂料相比，Nfinite Nanotechnology Inc.正在商业化。涂层仅几十纳米（十亿分之一的米）厚，因此它们不会影响可持续包装的堆肥性或可回收性，并且它们不含针孔，因此它们提供了出色的屏障特性。与传统的制造方法相比，AP-Sald是无溶剂和露天的，因此更便宜，更快且绿色。在这个项目中，研究团队和Nfinite将在不同的可持续包装材料上优化其新颖的AP-Sald屏障涂料，将技术转移到滚动涂层过程中，并为可持续包装行业开发额外的涂料材料。项目将解决剩余的商业化障碍，使Nfinite可以将其AP-Sald设备出售给包装行业。该项目将促进创新的创业公司的增长，并为加拿大带来巨大的经济和环境利益。该技术将同时减少塑料废物，食物浪费和相关的温室气体排放。
