“…However, the most common and exploited organic fillers that are applied polysaccharide‐based matrices are cellulosic fillers particularly MCC NCC, also known as cellulose nanowhiskers or CNCs due to their interesting chemical similarities with the polysaccharide structure . This is particularly important to enhance mechanical and water barrier properties . The main source of MCC and NCC is usually from plants ranging from wood to non‐wood biomass (e.g., bamboo, cotton, corn, birch, aspen, jute, sisal, pine, kenaf, eucalyptus, and so on …”

The global shift towards biodegradable composite has made polysaccharides a green alternative to synthetic polymers owing to their biocompatibility, sustainability, and ecofriendly biomaterials. Despite the limitations in their applications, many studies have validated the effectiveness of using organic or inorganic fillers to ameliorate their mechanical and barrier properties. However, the understanding of how polysaccharides matrix is enhanced by fillers is still inexplicit. Hence, it is imperative to review the effects of using inorganic and organic fillers in some prominent polysaccharides in terms of mechanical and water barrier properties while taking into account the function of filler morphology, size and loading. Although it is intricate to indicate the best filler used for each of the polysaccharides matrices, this review served as a “food for thought” on the established works of enhanced‐matrix filler combinations aimed at improving the mechanical and barrier properties of biodegradable films based on neutral or negatively charged polysaccharides‐based composite films for potential application in food packaging, agriculture, biomedicine and constructions sector. © 2018 Wiley Periodicals, Inc.

Starch-corncob cellulose-cassia oil (SCC) composite films are fabricated by a solution casting technique, using corn starch as substrate, corncob cellulose fibers as the reinforcing material, and cassia oil added as the bacteriostatic agent. The morphology, transmittance, thermal properties, permeability, and mechanical properties of the SCC composite films are studied. The SCC composite film with 2% w/w corncob cellulose and 0.2% v/w cassia oil show good properties. The surface of the SCC composite film is smooth, and the components are evenly mixed as shown by scanning electron microscopy images. Fourier transform infrared spectroscopic analysis also show that both cassia oil and corncob cellulose molecules successfully enter the starch matrix, and a stable starch-corncob cellulose cassia oil composite film is formed. Thermogravimetric analysis of the SCC composite film shows that the film has good thermal stability and good heat resistance. In the SCC composite film with 2% w/w corncob cellulose, tensile strength decreases the content of cassia oil increases, but elongation at break shows the trend of increasing initially and then decreasing. The SCC composite films have good mechanical properties and can keep fruit fresh, indicating that the composite film can be used as a good food packing material.

“…The high cost of bioplastic production hindered its further commercial success, so alternative low cost and renewable substrate from agricultural residues has been proposed to reduce the cost of such plastics . Starch‐based composite films are the sustainable alternative to petroleum‐based nondegradable films in food packaging and handling . Owing to its bioavailability and biodegradability as a matrix and filler in recent decade, attention has been focused on starch‐based films in agricultural applications, medicinal drug release, and other fields of packaging .…”

Starch-based biodegradable films were prepared by using solution-casting method and reinforced by agricultural residues [apricot and walnut shell (APS and WNS) powder]. The powder of both shells was added in different ratios (0, 2.5, 5, 7.5, and 10%) to investigate the microstructures and performances (mechanical and thermal properties) of the starch-based film. Different techniques such as impact, tensile testing, scanning electron microscope, optical microscope (OM), X-ray diffraction (XRD), water vapor transmission rate (WVTR), and dynamic mechanical analysis were applied to study the thermomechanical and barrier properties of the composite films. Results showed that the incorporation of both shells significantly improved the WVTR and mechanical properties of starch-based films. The shells powder was significantly increased the Young's modulus and tensile strength of the starch-based films. Both OM and SEM results showed reasonably good compatibility between starch and reinforced shells. OM and XRD indicated that the APS and WNS not only retained their crystalline structure in the film but they also strengthened the peak intensity of the film. This phenomenon can be used to explain the mechanism of mechanical reinforcement. Since all the components used in the preparation of the films are food grade ingredients, it is expected that the films developed in this work will be used for food packaging applications.
