“…As matter of fact, the addition of fillers generally aims not only to enhance film mechanical properties but also to confer them stability for various applications that often require film exposure to a high moisture environment. Thus, Figure 6 shows that the observed mechanical reinforcement due to the presence of either NC or LF in the HP film matrix led also to a decrease of the film moisture content, probably due to a weakened water trapping ability of the biocomposite films as a result of the denser structure of their matrix [37].…”

Nanocrystalline cellulose (NC) and a lignin-containing fraction (LF) were obtained from egagropili, the so called sea balls produced from rhizome and stem fragments of Posidonia oceanica that accumulate in large amounts along the coastal beaches in the form of tightly packed and dry materials of various dimensions. Both egagropili fractions have been shown to be able to improve the physicochemical properties of biodegradable films prepared from protein concentrates derived from hemp oilseed cakes. These materials, manufactured with a biodegradable industrial by-product and grafted with equally biodegradable waste-derived additives, exhibited an acceptable resistance with a still high flexibility, as well as they showed an effective barrier activity against water vapor and gases (O2 and CO2). Furthermore, both NC and LF decreased film moisture content, swelling ability and solubility, thus indicating that both additives were able to improve water resistance of the hydrocolloid films. The exploitation of egagropili, actually considered only an undesirable waste to be disposed, as a renewable source of reinforcing agents to blend with different kinds of polymers is suggested.

“…The decrease for transmittance is attributed to the impermeability of the light‐impermeable nanocellulose and the inhomogeneous distribution in the composite films. In addition, the size of CMCNFs is larger than CMCNCs, which causes a further decrease to the transmittance of the CMC/CMCNFs composite films 7,47 …”

“…5 However, the application of bio-based materials is limited due to disadvantages such as poor mechanical properties and poor thermal stability. 7,8 Carboxymethyl cellulose (CMC), a material possessing thermal gelation and excellent film-forming ability, is derived from abundant natural polymer cellulose, 9,10 which has already been used in the food industry as a thickener, stabilizer or edible film owing to its nontoxicity. 11,12 Although CMC is now being utilized in differently edible film formulations, 13 poor mechanical properties and thermal stability limit its wide applications.…”

In this work, carboxymethyl cellulose (CMC) with low substitution degree, followed by different posttreatments, was applied to prepare treelike CMC nanofibrils (CMCNFs) and rodlike CMC nanocrystals (CMCNCs), and their performance in CMC composite film was evaluated simultaneously. From transmission electron microscopy results, it was found that the treelike CMCNCFs exhibited a lager aspect ratio compared to the rodlike CMCNCs. As for reinforcing CMC film, 4 wt% was the best adding amount, at this time, the tensile strength of CMC/CMCNFs and CMC/CMCNCs composite films was increased by 72.1% and 47.3%, respectively. Moreover, adding these nanofillers to CMC also could enhance the thermal stability of composite films slightly, while the transmittance of composite films was reduced at the same time. In addition, CMC/CMCNFs film was designed as a packaging box to determine its performance. Therefore, this study could reveal the differences of properties for composites with different types of nanocellulose and provide a foundation for further application of nanocellulose.
