Development and Prospects of Recycled Packaging in Circular Economy System: A Review

This study focuses on the concept of the circular economy within industrial systems and its relevance to industry, practitioners, scientists, and the govern-ment. The review examines different models of the circular economy, particular-ly those addressing material engineering for packaging substitution. It explores methods to enhance barrier performances and maintain sealing integrity in the sealing layer film, offering a unique combination of properties that can contribute to the development of the circular economy. The study emphasizes the need to address the limitations of the material properties and explores potential recycling methods, including mechanical and chemical recycling, for plastic films. State-of-the-art research in material engineering, sustainable targets, indicators for packaging design, and manufacturing processes is reviewed. The investigation aims to achieve sustainable objectives and validate the recyclability of packaging designs. In conclusion, this study highlights the opportunities for material engineering within the circular economy and provides insights into the development and implementation of recycling methods for plastic films.
