摘要

Growing environmental concerns over petroleum-based packaging have accelerated the switch to bio-based alternatives. This review discusses emerging green biopolymers as food packaging alternatives, focusing on their physicochemical properties, environmental impact, and functional usefulness. This study compares biopolymers with conventional polymers on thermal stability, mechanical strength, barrier performance, and biodegradability. Biopolymer extraction from agricultural and agro-industrial waste is valued, linking packaging innovation with circular economy concepts. The review discusses moisture sensitivity, heat resistance, and long-term stability issues in important biopolymers. Also, critically analyze research gaps in standardization, nanocomposites safety, and cost competitiveness. Artificial intelligence, Internet of things, and blockchains are also considered for material design, shelf-life prediction, and supply-chain traceability. In addition to this, detailed upgradation of sustainable biopolymer-based packaging methods for scalable, high-performance, and circular food packaging has been elaborated. Moreover, these biopolymers have gained consideration owing to their prospective to lessen carbon footprints and reduced waste generation which has also been elaborated in this review.
