Abstract

As the world shifts away from plastic products and embraces a more environmentally friendly approach, industries are exploring new and creative ways to create sustainable alternatives. Paperworks has developed a sustainable barrier coating to be placed on the inside of specific paperboard packages (tea boxes, etc.). The sustainable barrier must be protective against moisture and grease, as well as meeting standard strength properties. This study aims to investigate these properties, determine a suitable coat weight and create a cost analysis for implementing this coating. In doing these experiments, three different coat weights were compared against an uncoated control sample. The methods of attacks were in line with the TAPPI standards. It was determined that all the coat weights performed well under moisture at 23C and 50 percent relative humidity. Additionally, all the coat weights received a kit rating of 12, meaning they are excellent against oil and grease. However, the hydrophilic component in the coating makes it potentially unsuitable for high temperature and high humidity conditions. It is recommended to add additional additives if needed to meet this requirement.
