Synthetic packaging materials are known to cause serious environmental and human health problems. Among the eco-friendly biopolymers from nonfood sources that are suitable for packaging applications, pectin is a promising candidate. However, native pectin films (NPF) exhibit poor mechanical strength, high hydrophilicity, and poor gas diffusion barrier properties. These shortcomings offset the advantages of pectin as a potential packaging material. To address these limitations, in this study, hematite nano ellipsoids (HNEs) were incorporated as fillers to reinforce native pectin films. This reinforcement resulted in substantial improvements in the mechanical properties, hydrophobicity, thermal stability, barrier properties, and optical attributes of pectin films. Compared to NPF, the pectin-hematite composite film exhibited a 35% increase in tensile strength, a 30° increase in contact angle, a 6-fold increase in the oxygen diffusion barrier properties, and a 20% increase in the water vapor barrier properties. This study presents a sustainable, biocompatible, and biodegradable packaging solution by capitalizing on eco-friendly biopolymer and nanoparticle engineering. |
