PACKAGING TECHNOLOGY Preparation and characterization of sodium carboxymethyl cellulose/cotton linter cellulose nanofibril composite films, A.A. Oun & J-W Rhim, Carbohydrate Polymers , 127. Crystalline cellulose nanofibril was used as a filler to reinforce sodium carboxymethyl cellulose film. The composite films have a high potential to be used as an edible coating or packaging films for the extension of shelf life of fresh and minimally processed fruits and vegetables. Effect of the addition order and amylose content on mechanical, barrier and structural properties of films made with starch and montmorillonite, C.A. Romero- Bastida et al , Carbohydrate Polymers , 127. This study considered the effect of amylose content (30% and 70%), montmorillonite fraction (5 and 15%) and preparation method on mechanical and barrier properties of starch/clay nanocomposites prepared by casting. Antimicrobial nanostructured starch based films for packaging, A.S. Abreu et al , Carbohydrate Polymers , 129. Montmorillonite modified with a quaternary ammonium salt C30B/starch nanocomposite (C30B/ST-NC), silver nanoparticles/starch nanocomposite (Ag-NPs/ST-NC) and both silver nanoparticles/C30B/starch nanocomposites (Ag- NPs/C30B/ST-NC) films were produced. Results indicated that the starch films incorporated with C30B and Ag-NPs have potential to be used as packaging nanostructured material. Bio-nanocomposite films reinforced with cellulose nanocrystals: Rheology of film- forming solutions, transparency, water vapor barrier and tensile properties of films, N. El Miri et al , Carbohydrate Polymers , 129. This study was aimed to develop bio- nanocomposite films of carboxymethyl cellulose (CMC)/starch (ST) polysaccharide matrix reinforced with cellulose nanocrystals (CNC) using the solution casting method. The as- produced films exhibited good optical transparency, reduced WVP and enhanced tensile properties, which are the main properties required for packaging applications. Antimicrobial polyethylene wax emulsion and its application on active paper-based packaging material, X. Xu et al , Journal of Applied Polymer Science , 132 (27). Antimicrobial polyethylene wax (PEW) emulsions, prepared by emulsifying polyethylene wax grafted with polyhexamethylene guanidine hydrochloride (PEW-g-PHGH), were used as wet-end additives or coating materials for making hydrophobic and anti-mould paper. Modelling of Migration from Printing Inks on Paper Packaging, Z.-W. Wang et al , Packaging Technology and Science , 28 (4). The migration model of contaminants from inks on paper packaging to food is developed based on the penetration of ink in paper and Fick's diffusion. The printed paper is divided as ink layer and paper layer. The model equation is solved, and the migration expression is obtained by using the method of separation of variables. The Potential of NanoCellulose in the Packaging Field: A Review, F. Li et al , Packaging Technology and Science , 28 (6). Nanocellulose particles can be utilised as fillers, in composites manufacture, as coating and as self-standing thin films. Very few of the several reviews that recently appeared on this topic in the scientific literature, however, summarised the potential of cellulose in nanoform specifically for the packaging field. In the present review, the remarkable chemical and physical properties of nanocellulose are introduced and discussed with specific reference to packaging needs.
