“…Reported studies on cellulose nanofibrils (CNF), derived from different cellulose sources including bleached wood fiber, cotton, and agricultural residues show a yet untapped opportunity for uses in diverse applications such as in reinforcement of nanocomposites with thermoplastic and thermoset polymers, membranes, coatings, packaging, and film materials . Large scale production of CNF is possible by the combined effects of chemical, enzymatic, and mechanical treatments such as grinding, high‐pressure homogenization, and microfluidization …”

Lignocellulosic nanofibrils (LCNF) are produced from a single source of unbleached, oxidized wood fibers by serial disintegration, high‐pressure microfluidization, and homogenization. Sequential centrifugation enables fractionation by fibril width (≈5, ≈9, and ≈18 nm). LCNF residual lignin of high molecular mass reports together with the finest fraction (LCNF‐fine), whereas the more strongly cellulose‐bound lignin, of relatively lower molecular mass, associates with the coarsest fraction (LCNF‐coarse). Hot pressing softens the amorphous lignin, which fills the interstices between fibrils and acts as an in‐built interfacial cross‐linker. Thus, going from the LCNF‐fine to the LCNF‐course films, it is possible to obtain a range of values for the structural consolidation (density from 0.9 to 1.2 g cm−3 and porosity from 19% to 40%), surface roughness (RMS from ≈6 to 13 nm), and strength (elastic modulus from 8 to ≈12 GPa). The concentration of free hydroxyl groups controls effectively the direct surface interactions with liquids. The apparent surface energy dispersive component tracks with the total surface free energy and appears to be strongly influenced by the higher porosity as the fibril lateral size increases. The results demonstrate the possibility to tailor nanofibril cross‐linking and associated optical and thermo‐mechanical performance of LCNF films.

“…Also, paper coating with nanofibrillated cellulose or nanofibrillated cellulose/chitosan nanoparticles has been reported to decrease the porosity and water absorption of paper. 22 From the above discussion, it can be concluded that chitosan improved the WVPR of coated paper.…”

“…In another study, it was observed that the strength of paper sheets was greatly increased by adding the dialdehyde chitosan/crosslinked amino starch composite to pulp, specifically, the tensile index and burst index of the paper sheets was increased by 31% and 35%, respectively. 23 Hassan et al 22 showed that the coating of paper sheets with a thin film of nanofibrillated cellulose or nanofibrillated cellulose/chitosan nanoparticles can improve the tensile strength properties of paper. Andze et al 24 reported that the molecular chitosan additive also improved the tensile index of dry paper by approximately 15-25%, the wet strength up to 9 times at 2.5% chitosan of the fiber weight.…”

Paper is widely used in the packaging sector. Water vapor barrier and water resistance properties of packaging paper need to be improved by changing the wettability of its surface with sizing agents or through coating with hydrophobic materials, such as paraffin wax, polyethylene, poly(ethylene terephthalate) and poly(butylene terephthalate). In this study, a biodegradable coating was applied on kraft paper. The application of chitosan as a coating on kraft paper sheets could be an alternative to commercial synthetic polymer coatings. Chitosan with microcrystalline cellulose (MCC) was used to coat kraft paper sheets. The different concentration of chitosan and MCC were evaluated. The application of 1% chitosan (4.7 g/m 2 ) alone lowered the water vapour permeability rate (WVTR) by 41.1%, the water absorption capacity (Cobb test) by 54.9%, while porosity decreased twice. An increase in chitosan concentration further improved these properties significantly. The addition of 1% MCC to 1% chitosan further reduced WVTR, porosity and Cobb 60 value. Also, a slight increase in the papermaking properties of coated paper was observed. MCC added to the chitosan coating increased the gloss value of the coated paper sheet. The addition of protein from leather mill wastes to the chitosan coating, instead of MCC, also improved these properties. However, coating both sides of the paper did not have the same effect.

“…The NFC-GGM composite films coated with GGM-Su2 were impermeable for 11 days at 50 °C and 40% RH, and for 9 months at 23 °C and 50% RH in a follow-up exposure test. Hassan et al (2016) developed films from NFC and chitosan nanoparticles (CHNP), and these displayed excellent grease resistance. They used the mixture to coat paper sheets, and the grease proof properties of coated paper were improved.…”

There has been increasing concern regarding environmental problems arising from the widespread use of petroleum-based plastic materials for packaging. Many efforts have been made to develop sustainable and biodegradable packaging materials to replace plastic products. The current review summarizes recent research progress in developing cellulose packaging materials to replace plastics used for cushioning and barrier packaging functions based on pulp fibers, cellulose nanofibers, and regenerated cellulose films to benefit from their renewability, sustainability and biodegradability. The cushioning packaging materials include molded pulp products and bio-based foams. Advanced cellulose films and paper can be good barriers for oxygen and carbon dioxide gases, as well as for water vapor. Several cellulose fiber-based packaging products have been commercialized in areas that used to be occupied solely by plastic products.
