Insights into bibliometric review for natural coatings for paper-based food packaging: trends, perspectives, and future directions

Abstract This paper provides an insightful analysis of research trends, publication venues, and future perspectives in the realm of Natural Coatings for Paper-based Food Packaging. Through bibliometric and keyword analyses, alongside co-authorship network visualization, it illuminates the evolving landscape of this interdisciplinary field. Findings reveal a notable surge in interest and collaboration, with a focus on sustainable materials, functionality enhancement, and barrier properties. Key themes include structural design, biopolymers, essential oils, and water resistance. Top journals such as the International Journal of Biological Macromolecules, Coatings, and Polymers serve as prominent platforms for disseminating research in this domain. Looking ahead, future research should explore innovative approaches like composite materials and essential oil applications. Understanding the synergistic effects of cellulose and essential oils, optimizing coating parameters for oxygen barrier performance, and enhancing water resistance are crucial avenues for advancing sustainable packaging solutions. Collaboration across disciplines and international borders will be vital in addressing the multifaceted challenges facing the food packaging industry. By leveraging interdisciplinary expertise and sustainable materials, researchers can drive progress towards safer, more efficient, and environmentally friendly food packaging solutions, benefiting both consumers and the planet.
