Abstract:
The paper industry faces increasing challenges in developing moisture-resistant and biodegradable\r\npaperboard materials to replace plastic-based packaging. Conventional paperboard, while renewable\r\nand recyclable, is prone to moisture absorption that weakens its structural integrity and limits its\r\nusability in food and liquid packaging. Smart coating technologies have emerged as a sustainable\r\ninnovation that enhances the water resistance, mechanical strength, and barrier properties of\r\npaperboard without compromising recyclability. This research investigates the development and\r\nperformance of smart coatings—comprising nanocellulose, biopolymer blends, and stimuliresponsive materials—that provide superior moisture resistance and adaptive behavior under varying\r\nenvironmental conditions. Experimental analysis and modeling demonstrate that these coatings can\r\nreduce moisture absorption by up to 70% and improve mechanical durability by 40%. The study also\r\nevaluates the environmental and economic implications of integrating smart coatings in industrialscale paperboard production. The findings confirm that smart coating technologies represent a key\r\nadvancement toward eco-efficient packaging systems that align with global sustainability objectives.
