The demand for these polymers has skyrocketed, making them broadly utilized polymers with a range of several applications. Plant, animal, and microbially derived biopolymers have piqued the interest of researchers. Because of their inherent properties like biodegradability, biocompatibility, inexhaustibility, and economic availability, the need for biodegradable polymers has been enhanced. Recent trends in the food packaging industry have shown the employment of biodegradable polymers with improved characteristics. This chapter emphasizes biodegradable polymers� development, classification, application, challenges, and market opportunities. The application of these polymers in active and intelligent packaging are summarized. This chapter also highlights the application of biodegradable polymers as an assuring green technique for assuring the quality and safety of food. � The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.Bacterial celluloseBiocompositesBiodegradable polymersFood packagingPHAPLABook chapterhttps://doi.org/10.1007/978-981-19-5743-7_1
