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...

“…The chemical structure of chitosan is very similar to that of cellulose, except for the replacement of one NH 2 group instead of OH on the glucose molecule. Recent studies revealed that it is widely used for medicine, edible packaging or coating, food additives, cosmetic, water treatment, and antifungal agents. − …”

In view of producing environmentally friendly materials without compromising the properties, new composites containing polylactic acid as matrix and chitosan, with or without keratin fibers have been obtained. The morphological, mechanical, rheological, and thermal characterizations of the composites were performed before and after accelerating weathering. In normal conditions, the presence of keratin improved the toughness and thermal stability of polylactic acid (PLA)/ chitosan material. Upon accelerated weathering, thermal degradation of the PLA matrix was faster in the presence of chitosan, as compared to the composite containing chitosan and keratin. Fractured surfaces of the exposed composites are rougher related to the unexposed samples, as revealed by SEM. XRD analysis recorded selective degradation of the amorphous part of the materials. The decrease of the complex viscosity values after UV exposure of the blends indicated that chain scission was the most prominent phenomenon in accelerated weathering tests.

“…There have been several reports of the biodegradation of composites that contained bacterial cellulose. − A starch/BC composite had degradation measured by determining the weight loss after soil burial and it was found that composites achieved 69% degradation within 3 weeks of burial . Bacterial cellulose contents and choice of culture medium were found to influence the degradation of poly(vinyl alcohol) (PVA)/BC composites when exposed to a single fungal strain in laboratory culture; however, in this study, biodegradation was only studied qualitatively and no overall measurement of biodegradation was made …”

Poly-3-hydroxybutyrate (PHB) and bacterial cellulose (BC) are both natural polymeric materials that have the potential to replace traditional, nonrenewable polymers. In particular, the nanofibrillar form of bacterial cellulose makes it an effective reinforcement for PHB. Neat PHB, bacterial cellulose, and a composite of PHB/BC produced with 10 wt % cellulose were composted under accelerated aerobic test conditions, with biodegradability measured by the carbon dioxide evolution method, in conjunction with spectroscopic and diffraction methods to assess crystallinity changes during the biodegradation process. The PHB/BC composite biodegraded at a greater rate and extent than that of PHB alone, reaching 80% degradation after 30 days, whereas PHB did not reach this level of degradation until close to 50 days of composting. The relative crystallinity of PHB and PHB in the PHB/BC composite was found to increase in the initial weeks of degradation, with degradation occurring primarily in the amorphous region of the material and some recrystallization of the amorphous PHB. Small angle X-ray scattering indicates that the change in PHB crystallinity is accompanied by a change in morphology of semicrystalline lamellae. The increased rate of biodegradability suggests that these materials could be applicable to single-use applications and could rapidly biodegrade in compost on disposal.
