“…tunicin whiskers. Angles and Dufresne (2001) found that such reinforcement in a starch matrix helped achieve a strong and continuous film. The cited authors proposed that the good film properties, when combining starch with cellulosic nanoreinforcement, could be attributed to hydrogen bonding.…”

This review article was prompted by a remarkable growth in the number of scientific publications dealing with the use of nanocellulose (especially nanofibrillated cellulose (NFC), cellulose nanocrystals (CNC), and bacterial cellulose (BC)) to enhance the barrier properties and other performance attributes of new generations of packaging products. Recent research has confirmed and extended what is known about oxygen barrier and water vapor transmission performance, strength properties, and the susceptibility of nanocellulose-based films and coatings to the presence of humidity or moisture. Recent research also points to various promising strategies to prepare ecologically-friendly packaging materials, taking advantage of nanocellulose-based layers, to compete in an arena that has long been dominated by synthetic plastics. Some promising approaches entail usage of multiple layers of different materials or additives such as waxes, high-aspect ratio nano-clays, and surface-active compounds in addition to the nanocellulose material.While various high-end applications may be achieved by chemical derivatization or grafting of the nanocellulose, the current trends in research suggest that high-volume implementation will likely incorporate water-based formulations, which may include water-based dispersions or emulsions, depending on the enduses.

"Nanocellulose in packaging," BioResources 12(1), 2143-2233. 2144 Keywords: Barrier properties; Water vapor transmission; Food shelf life; Oxygen transmission; Packages; Cellulose nanomaterials Contact information: a: Department of Forest Biomaterials, College of Natural INTRODUCTIONThere has been explosive growth in the publication of peer-reviewed articles that combine key words related to "packaging" and "cellulose," in combination with the terms "nanocellulose," "nanocrystal*," or "nanofibril*". As of November 2016, a search of this combination of terms showed about as many publications since the start of 2015, compared to all preceding years combined. Given such an acceleration of research around the world, it makes sense to ask whether this high amount of research effort has yet borne significant fruit. In light of this question, the emphasis of this review article is on research publications that shed light on known challenges to the successful implementation of nanocellulose products to enhance the performance of packaging.In principle, a nano...

“…During the last few decades, TPS has received considerable attention among the scientific world (John and Thomas 2008;Belhassen et al 2009;Cañigueral et al 2009;Chaleat et al 2012). As a result, numerous works have been published evaluating their mechanical and thermal properties, water uptake behavior, and/or degradation kinetics in an attempt to adapt these parameters to the technical demands of potential applications (Angles and Dufresne 2001;Carvalho et al 2005;Ayadi et al 2011). In recent years, some companies have started the mass production and commercialization of several starch-based biodegradable polymers.…”

aThough there has been a great deal of work concerning the development of natural fibers in reinforced starch-based composites, there is still more to be done. In general, cellulose fibers have lower strength than glass fibers; however, their specific strength is not far from that of fiberglass. In this work, alpha-fibers were obtained from alpha-grass through a mild cooking process. The fibers were used to reinforce a starch-based biopolymer. Composites including 5 to 35% (w/w) alpha-grass fibers in their formulation were prepared, tested, and subsequently compared with those of wood-and fiberglass-reinforced polypropylene (PP). The term "high-performance" refers to the tensile strength of the studied composites and is mainly due to a good interphase, a good dispersion of the fibers inside the matrix, and a good aspect ratio. The tensile strength of the composites showed a linear evolution for fiber contents up to 35% (w/w). The strain at break of the composites decreased with the fiber content and showed the stiffening effects of the reinforcement. The prepared composites showed high mechanical properties, even approaching those of glass fiber reinforced composites. Keywords INTRODUCTIONIt is commonly accepted that biopolymers and bio-fibers have the potential to replace or reduce the consumption of fossil fuel-derived plastics. In addition, to facilitate the recycling of these materials, such replacement should lead to reductions in energy consumption, pollution, and CO 2 emissions. Hence, fiber-reinforced composites are often described as eco-friendly materials. However, the mechanical properties and/or the price of such composites have rendered them inadequate for many applications to date. In general, cellulosic fibers have inferior strength compared to their synthetic counterparts, such as aramid, carbon, and glass fibers.Due to their lower density, some natural fibers have a specific strength not far from those of fiberglass. On the other hand, bio-based matrices (such as polylactic acid or polyhydroxybutyrate) remain more expensive than petroleum-derived polymers. Nevertheless, thanks to their price/performance balance, ongoing innovations are offering new commercial opportunities for bio-based polymers and their composites in several applications. PEER-REVIEWED ARTICLEbioresources.com Gironès et al. (2013). "Alpha/starch composites," BioResources 8(4), 6121-6135 6122Compared to lactones, butyrates, valerates, and other monomers used for the synthesis of biodegradable polymers, starch is an inexpensive product whose transformation into a thermoplastic polymer can be accomplished in a rather straight-forward manner (Coombs and Hall 1998;Teixeira et al. 2007;Averous and Halley 2009;Dogossy and Czigany 2011;Gandini 2011). As a result, thermoplastic starch (TPS) is considered one of the most promising biopolymers for large-scale applications. During the last few decades, TPS has received considerable attention among the scientific world (John and Thomas 2008;Belhassen et al. 2009;Cañigueral et al. 2009;Cha...
