Editorial: Biopolymer-based food packaging: design, functionality, and industrial applications
AI summary Read the abstract
This editorial introduces a collection of 8 articles on plant-based food packaging materials, covering topics like frozen food storage and shelf-life testing of a packaged Indian flatbread. The collection discusses how combining materials science with sustainability goals could lead to safer, more environmentally friendly packaging alternatives to conventional plastics.
This research topic includes a total of 8 published research and review articles, as summarized below, contributed by 26 national and international authors.The the first article i.e., 'Frozen Food Packaging: Recent Technological Advances and Future Perspectives', recent advancements in frozen food packaging have been discussed in terms of barriers to moisture and oxygen migration, mechanical resistance, and lowtemperature stress resistance. Biopolymer blends and nanocomposites have been discussed, which prevent moisture and oxidation, and future advancements in this field have been projected (Adhikary et al., 2026; that discusses the standardization of the process and shelf-life estimation of puran poli, an Indian sweet flatbread, packed in retort pouches under varying storage conditions. The paper provides an insight into how the retort process technology helps to ensure that the packaged food is not only safe for consumption from a microbial point of view, but it also has increased shelf-life and sensory properties retained. The research allows to identify optimal processing conditions and to estimate the performance of the packaging material in order to guarantee the maintenance of the quality of the product under ambient and accelerated storage conditions. To sum up, the research topic illustrates how interdisciplinary innovation may transform the food packaging sector. Through the integration of material science, sustainability frameworks, and industrial viability, such research contributions can pave the way for safer, more environmentally friendly, and culturally acceptable packaging alternatives. Their congruence with the UNSDGs highlights the importance of biopolymer research on a worldwide scale, providing concrete methods to prevent plastic pollution, protect food systems, and advance sustainable development.
