“…Thus, superior transparency of films incorporating fibrillated cellulose has been reported mainly in cases where the cellulose has been thoroughly broken down to a very small size (Nogi et al 2009;Plackett et al 2010;Siro et al 2011). Siro et al (2011) found that multiple passes through a homogenizer device during the preparation of NFC tended to improve the transparency of the resulting films.…”

“…In particular, very high performance, relative to plastic-based materials, has been reported for the oxygen permeation resistance of certain nanocellulose-based films (Fukuzumi et al 2009;Syverud and Stenius 2009; Aulin et al 2010a;Hult et al 2010;Plackett et al 2010; Rodionova et al 2012a,b;Shimizu et al 2016). While a high level of resistance to oxygen permeation has been reported, many other studies have revealed much lower performance of cellulose-based films and coatings in terms of resistance to water vapor transmission.…”

“…In this way, nanocellulose-related films have the potential to either increase the shelf life of foods, to prevent the accumulation of unwanted odors or contamination of the food, or conversely to avoid the escape of food odors. The following articles indicate strong performance of nanocellulose-containing films as oxygen barriers (George et al 2005;Pääkkö et al 2007;Fukuzumi et al 2009;Syverud and Stenius 2009; Aulin et al 2010a; Edlund et al 2010;Hult et al 2010;Plackett et al 2010;Yang et al 2011;Charani et al 2013;Fortunati et al 2012b;Martínez-Sanz et al 2012; Rodionova et al 2012a,b;Savadekar et al 2012;Stevanic et al 2012; Espino-Pérez et al 2013;Li et al 2013a;Martínez-Sanz et al 2013a;Österberg et al 2013; Paunonen 2013a,b;Iotti 2014;Kumar et al 2014;Lavoine et al 2014c;Liu et al 2014;Miettinen et al 2014;Ibn Yaich et al 2015;Rojo et al 2015;Cheng et al 2016;Shimizu et al 2016). …”

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.

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...

“…This was exemplified for poly(S-co-BuA) reinforced with cellulose nanoparticles extracted from sugar beet and submitted to different hydrolysis conditions (Azizi Samir et al, 2004a). The crack-stopping capability of cellulose microfibrils and improvement of strength were also observed for BC reinforced phenol formaldehyde (Nakagaito and Yano, 2004) and MFC reinforced amylopectin films (Plackett et al, 2010). As the acid concentration increased, it was observed that the length of the microfibrils decreased because of the increased probability of removal of the amorphous material with the concentration of acid.…”

The mechanical properties of nanocellulose are its most important and best investigated asset. Indeed, these properties are profitably exploited by Mother Nature since cellulose is a structural polymer that provides the mechanical strength and stiffness to higher plant cells. Impressive mechanical properties, nanoscale dimensions and high aspect ratio of nanocellulose make it therefore an ideal candidate for the reinforcement of polymeric materials. To improve the mechanical properties of the host material and take advantage of this property, special care needs to be paid to the processing of the nanocomposite. Indeed, it is well-known that the macroscopic mechanical properties of heterogeneous materials depend on the specific behavior of each phase and the composition (volume fraction of each phase), but also on the morphology (spatial arrangement of the phases) and the interfacial properties.By adding conventional high modulus reinforcements into a polymer, usually the modulus and the strength of the composite are improved, while the ductility and the impact strength are decreased. In the case of well dispersed nanoparticles, the modulus and strength can be improved without any significant change in ductility since they do not create high stress concentrations due to their nanosize.In the recent years, great interest has been focused on investigating the use of cellulose nanocrystals or MFC as a reinforcing phase in a polymeric matrix, evaluating the mechanical properties of the resulting composites and elucidating the origin of the mechanical reinforcing effect. Dynamic mechanical analysis (DMA) is a powerful tool to investigate the linear mechanical behavior of materials in a broad temperature/frequency range and it is strongly sensitive to the morphology of heterogeneous systems. Non-linear mechanical properties are generally accessed through classical tensile or compressive tests.

“…These films show excellent oxygen barrier properties at low relative humidity due to their high crystallinity and highly compacted structure (Belbekhouche et al, 2011;Minelli et al, 2010;Plackett et al, 2010;Syverud & Stenius, 2009). It has been reported that the denser structure and the formation of entanglements in films prepared from microfibrillated cellulose gives rise to increased barrier to gases as compared to cellulose nanowhiskers' films (Belbekhouche et al, 2011).…”
