The growing demand for sustainable packaging has spurred research into biopolymer-based solutions and their application to paper substrates. This study compares the of low solids, high viscous aqueous alginate chitosan on two different substrates using a laboratory film press coater purpose-built spray coating unit, with focus barrier performance practical industry considerations. Key parameters investigated are air flow rate, water vapor transmission grease resistance. Results showed that due solids content applied biopolymer solutions, required double-layer coat weights exceeding 4 g/m², making it less viable industrial application. In contrast, allowed higher in single step. properties coated samples, compared coatings, varied substrate: performed better one substrate worse other. Contact angle measurement suggested is more suitable hydrophilic because improved surface wetting. also identified issues drying conditions pinholes affecting quality indicating need further optimize these parameters.

Enhancement of the mechanical properties and water barrier properties of thermoplastic starch nanocomposite films by chitin nanofibers: Biodegradable coating for extending banana shelf life

Journal of Materials Research and Technology, Journal Year: 2023, Volume and Issue: 26, P. 5617 - 5625

Published: Aug. 29, 2023

Starch-based films have limited applications due to their hydrophilicity and poor mechanical performance. Herein, thermoplastic starch (TPS) nanocomposite with chitin nanofibers (ChNFs) extracted from shrimp-shell waste were successfully fabricated using a solvent casting method. We investigated the effects of ChNF loadings on physical, mechanical, water vapor barrier properties films. The well-dispersed ChNFs within soft matrix associated formation interfacial bonding between facilitated efficient stress transfer stiff ChNFs. Additionally, presence created tortuous pathways films, which could impede diffusion molecules. This resulted in significant improvement properties, wettability, resistance, nanocomposites. Compared results obtained neat TPS nanocomposites reinforced exhibited 300% higher tensile stress, 603% Young's modulus, considerable increase contact angle, shifting 86.2° 98.6°. Furthermore, ChNF-reinforced showed no fragmentation after being soaked for 12 h under vigorous stirring, whereas disintegrated same conditions. Interestingly, we found that coating suspension bananas effectively delayed aging, preventing color change green yellow. promising result demonstrates potential developed extend shelf life fresh food produce, reducing reliance single-use petroleum-based packaging.
