Abstract

Abstract In the pursuit of sustainable packaging to combat plastic pollution, sodium alginate, a renewable biopolymer, holds promise but demands enhancements for brittleness and moisture sensitivity. This study compares ionic crosslinking and polymer blending to develop high‐performance films from a tensile strength‐optimized formulation. Ionic crosslinking with CaCl 2 boosts tensile strength to 41 MPa but induces brittleness (
