“…Alternatively, nanofibrillated or microfibrillated cellulose has been added to suspensions of ordinary wood-pulp fibers in order to achieve higher strength of the resulting paper (Ahola et al 2008a,b;Eriksen et al 2008;Schlosser 2008;Guimond et al 2010;Song et al 2010;Taipale et al 2010;Gao et al 2011;Husband et al 2011;González et al 2012;Johansson et al 2012;Charani et al 2013;Ankerfors et al 2014). Slower dewatering during paper forming has been observed (Taipale et al 2010), though residual lignin and added cationic polymers have been found to be helpful to promote dewatering in such cases.…”

“…As noted by Syverud and Stenius (2009), such coating layers can increase paper strength and reduce oxygen transmission through the paper. Charani et al (2013) compared the effects of adding microfibrillated cellulose to the fiber slurry or as a coating on paper. The coating approach was found to be more effective in reducing air permeability.…”

“…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.

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...

“…An earlier study reported that the mechanical properties of handsheets from unbleached kraft hardwood pulp could be improved to the tune of 67% by replacing only a small amount (approximately 6% w/w) of base pulp with MFC (Rezayati Charani et al 2013). Another study showed that MFC (2.5% to 5.0%) could improve the mechanical properties of papers, mainly z-strength and fracture toughness (Ankerfors et al 2014).…”

Micro/Nano-fibrillated Cellulose from Cotton Linters as Strength Additive in Unbleached Kraft Paper: Experimental, Semi-empirical, and Mechanistic Studies

et al. 2017

Microfibrillated cellulose (MFC) and nanofibrillated cellulose (NFC) isolated from cotton linters were evaluated as a strength additive in unbleached kraft paper and compared with semi-empirical and mechanistic models. The z-directional tensile strength was enhanced due to NFC and MFC. The tensile energy absorption (TEA) derived via integrating the z-directional stress-strain curve was 29.165 J/m 2 , 120.658 J/m 2 , and 187.768 J/m 2 for the control, MFC, and NFC, respectively. Burst factor significantly increased from 11 to 14 for 10% MFC, while no increase was observed in NFC. From TEA predictions by semi-empirical models, a modified Page equation, Shear-lag, and a negative trend was found due to increased relative bonded area (RBA) with the addition of MFC/NFC. The mechanistic model used six mechanisms involved in binding the fibers and predicted the increased trend of TEA. The increased TEA due to NFC contributed to z-directional tensile strength, but not to the tensile indices and tear factor. This was ascribed to the large size difference of NFC with base pulp fibers and a higher RBA.

“…It has been shown in many studies that aqueous suspensions of MFC/NFC are highly shear thinning and show gel-like properties, especially at increased concentrations (Herrick et al 1983;Pääkko et al 2007;Agoda-Tandjawa et al 2010;Rezayati Charani et al 2013;Saarikoski et al 2015;Žepic et al 2014). The rheology of a high consistency furnish that contains large amount of MFC/NFC together with fillers and cellulose fibers was also observed to be governed by the swelling and gel-like properties of the MFC/NFC, as described by Dimic-Misic et al (2013).…”

Forming and Dewatering of a Microfibrillated Cellulose Composite Paper

et al. 2015

An approach is demonstrated for the manufacturing of a microfibrillated cellulose (MFC) composite paper. A key element in the manufacturing paradigm is the use of high consistency suspensions to improve retention and minimize the need for water removal after forming. The rheological characterization of the composite furnish, which contained 70% structured pigment, 20% MFC, and 10% pulp fibers, revealed a gel-like shear thinning behavior of the suspension, which differs greatly from traditional fiber-based papermaking furnishes. The results from laboratory and pilot scale studies show that the headbox consistency range from 5 to 10% offers the best combination of processing, forming characteristics, retention, and dewatering. While the furnish dewatering in laboratory scale was very problematic, under suitable dynamic conditions the wire section dewatering was excellent. The results of this study suggest that the MFC composite can be manufactured on a modified paper machine and that the final product will have an attractive cost structure.
