Biopolymer‐Coated Paper Composites for Sustainable Packaging

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conventional plastic packaging, though dominant in food and flexible applications, poses serious environmental concerns due to its persistence and limited recyclability. To address this challenge, this study develops bio‐based coated paper composites as sustainable alternatives. Paper, while biodegradable, lacks adequate barrier properties. To
