Biodegradable food packaging represents a significant advancement in the pursuit of environmental sustainability within the food industry. Unlike traditional plastics, which can persist in ecosystems for generations, these innovative materials—derived from natural polymers, plant sources, or edible coatings—are engineered to decompose safely, minimizing ecological disruption. Examples such as starch-based films, cellulose, polylactic acid (PLA), and chitosan demonstrate considerable progress in mechanical strength, barrier function, and overall performance.Beyond their environmental advantages, these packaging solutions effectively protect food from contamination and spoilage, thereby extending shelf life. They also align with growing consumer demand for clean-label and eco-friendly products. The adoption of biodegradable packaging enables manufacturers to reduce their environmental footprint, comply with evolving regulatory standards, and position themselves at the forefront of sustainable innovation in the marketplace.
