The material composition and structural design of packaging significantly influence its recyclability, with certain types classified as “Poor recyclability” due to inherent structural limitations. This study investigates the primary factors that hinder recyclability, focusing on paper cartons, PET bottles, and glass bottles, and explores strategies for structural improvement and alternative technologies. Key limitations were identified, including aluminum-laminated layers in paper cartons, non-standard coloring in glass bottles, and the use of composite materials in PET bottles. To address these challenges, various alternative technologies were reviewed, such as SiOx-coated films, mono-material PET, Diamond- like Carbon (DLC) coatings, and full-body shrink labels. Additionally, commercial applications of these technologies are introduced to demonstrate their practical feasibility. Overall, this research provides an in-depth analysis of material and structural innovations aimed at improving packaging recyclability and suggests relevant policy directions. The findings are expected to serve as a foundational reference for the development of sustainable packaging solutions and future regulatory strategies.
