Abstract

ABSTRACT To address the global crisis of 6.3 billion tons of non‐degradable plastic waste, polysaccharides (starch, chitosan, cellulose, etc.) have emerged as sustainable alternatives for food packaging. This review systematically analyzes five representative polysaccharides, highlighting their structural engineering strategies (e.g., nanocellulose reinforcement) and functional modifications (e.g., anthocyanin‐based pH responsiveness). We propose a comprehensive framework integrating cost, performance, and policy factors to benchmark industrialization challenges of key polysaccharides, with starch‐nanocellulose composites identified as the most scalable candidate. Integrated intelligent‐active packaging…
