Current Concerns

The barrier properties of the cellulose packaging films are current concerns for the fields of fruits and vegetables fresh-keeping packaging. One such porous films commonly used the pore formers as hole-forming materials whereas the compatibility and dispersity were not better with the cellulose solutions. In this study, the porous cellulose packaging films were prepared with natural broad-leaved pulp and LiCl/DMAc with different types of coagulation baths. The effects of methanol, ethanol, isopropanol, LiCl/DMAc and deionized water coagulation baths on the physical structures, oxygen and water vapor permeabilities and mechanical properties of the films were measured. Based on the scanning electron microscpy (SEM) observation, the cross section was loose when used the alcohol coagulations, especially the films with ethanol coagulation showed dactylopores. It was also found that the oxygen permeability had obviously improving with the effect of ethanol, which compared with water vapor permeability of the films. The porous cellulose packaging films had better mechanical properties and up to 12.7MPa which would satisfy the usage in packaging.

Concerns about environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as consumer demand for high-quality food products have led to increased interest in the development of biodegradable packaging materials using annually renewable natural biopolymers. Inherent shortcomings of natural polymer-based packaging materials such as low mechanical properties and low barrier properties can be recovered by applying nanocomposite technology. Polymer nanocomposites, especially natural biopolymer-layered silicate nanocomposites, exhibit markedly improved packaging properties due to large nanoparticle surface area and their significant aspect ratios. Additionally, natural biopolymer is susceptible to microorganisms, resulting in good biodegradability, which is one of the most promising aspects of its incorporation in packaging materials and industries. The present review article explains the various categories of nanoclay and bio-based polymer-based composites with particular regard to their application as packaging materials. It also gives an overview of the most recent advances and emerging new aspects of nanotechnology for development of composites for environmentally compatible food packaging materials.
