Development of biodegradable packaging films from carboxymethyl cellulose and oxidised natural rubber latex.

The present study investigates the biopolymer packaging film developed from carboxymethyl cellulose (CMC) with varying concentrations of natural rubber latex (NR) and oxidised natural rubber latex (ONR) using the solvent casting method. The physicochemical properties of the CMC/NR and CMC/ONR film samples were characterised using FTIR, TG/DTA, DSC, SEM, and XRD analysis. The increased concentration of NR and ONR helped to enhance mechanical characteristics, superior UV resistance, enhanced resistance to oxygen and water vapour penetration, improved dimensional stability, and a reduction in the moisture retention ability of the film samples.

Recent advances in carboxymethyl cellulose-based active and intelligent packaging materials: A comprehensive review.

Researchers have concentrated on innovative approaches to increase the shelf life of perishable food products and monitor their quality during storage and transportation as consumer demand for safe, environmentally friendly, and effective packaging develops. This comprehensive review aims to provide an overview of recent developments in carboxymethyl cellulose (CMC) chemical synthesis and its applications in active and intelligent packaging materials. It explores various methods for modifying cellulose to produce CMC and highlights the unique properties that make it suitable for addressing packaging industry challenges.

Grapefruit Seed Extract-Added Functional Films and Coating for Active Packaging Applications: A Review.

Recently, consumers have been increasingly inclined towards natural antimicrobials and antioxidants in food processing and packaging. Several bioactive compounds have originated from natural sources, and among them, grapefruit seed extract (GSE) is widely accepted and generally safe to use in food. GSE is a very commonly used antimicrobial in food; lately, it has also been found very effective as a coating material or in edible packaging films.
