Toward Sustainable Food Packaging: Innovations in Biodegradable Materials, Smart Technologies, and AI Integration

Abstract

Sustainable food packaging is gaining importance as the world increasingly addresses environmental concerns, food waste, and safety. Although traditional plastic packaging has long been effective, it significantly contributes to pollution and relies on nonrenewable resources. In response, this review highlights recent advancements in sustainable packaging, focusing on biodegradable, compostable, and recyclable materials. Moreover, it explores the integration of active and smart packaging systems, as well as the emerging role of artificial intelligence (AI) in improving packaging efficiency. Material innovations, such as biopolymers, cellulose-based films, algae-derived coatings, and nanomaterials, offer eco-friendly alternatives while still maintaining essential functions like barrier prot
