“…For example, Javed et al (2017) found that it was necessary to apply about four layers of a starch-PVOH layer onto glassine paper to overcome effects of defects within individual film layers. Tyagi et al (2018) observed that the incorporation of montmorillonite into CNC-based barrier films resulted in the elimination of defects observable by electron microscopy. It is suggested that related research focused on resistance to grease and oils could be considered in future research.…”

“…the same type of material but with a lower degree of size reduction compared to nanofibrillated cellulose. Cellulose nanocrystals (CNC) recently were used in a formulation that achieved resistance to grease (Tyagi et al 2018(Tyagi et al , 2019, and the results were attributed in part to the high crystalline content of CNC.…”

“…In view of the earlier discussion of tortuosity, it should not be surprising that promising results for resistance to grease and various gases have been achieved in systems in which highly platy minerals were used as an ingredient in film in barrier layers that were mainly comprised of MNFC or CNC (Sanchez-Garcia et al 2010;Liu et al 2011;Aulin et al 2012;Wu et al 2012;Rhim et al 2013;Rastogi and Samyn 2015;Tyagi et al 2018). Though most such studies did not report results for grease resistance, those that did so achieved promising results (Tyagi et al 2018(Tyagi et al , 2019Tayeb and Tajvidi 2019).…”

“…CNC was selected for the water-repellent layer due to its very high crystallinity, which can be expected to reduce its sensitivity to water. Earlier work by the same group showed that alkylketene dimer (AKD) also can be used in such formulations with CNC to increase resistance to water (Tyagi et al 2018). Figure 7 is a schematic diagram that incorporates features from the two last-cited articles.…”

A cost-effective, eco-friendly, and health-promoting packaging system that prevents the passage of greases and oils would fulfill an urgent need. This review discusses what is known about the highly divergent technological paths that have been studied to achieve these objectives. Before the emergence of plastic films, the paper industry addressed these objectives in two ways, by parchmentizing and by high levels of refining of the fibers. Parchmentizing means passing the paper through a bath of concentrated sulfuric acid, followed by rinsing out the acid and drying the sheet. Though both parchmentized paper and highly refined greaseproof paper products are still made, they have been substantially displaced by oil-repellent fluorocarbon treatments of paper. The fluorocarbon treatments have allowed papermakers to achieve greaseproof properties with ordinary paper machine equipment at ordinary refining levels and without a need to immerse the paper in strong acid. Now, however, due to environmental concerns and regulations, the paper industry needs more options. Some promising directions in published research include advances in chemistry, superoleophobic surfaces, nanocellulose films, and systems to protect nanocellulose films from the effects of moisture.

“…The nanoparticles also were an efficient UV blocking agent. Tyagi, P. et al obtained an improved paper-based package material by coating it with a composite made of nanocellulose, montmorillonite, soy protein, and alkyl ketene dimer [ 221 ]. When researchers obtain similar composites based on cellulose or chitosan (with montmorillonite and essential oils for example) the intrinsic antibacterial activity of chitosan will always make the difference between them [ 222 ].…”

This review presents a perspective on the research trends and solutions from recent years in the domain of antimicrobial packaging materials. The antibacterial, antifungal, and antioxidant activities can be induced by the main polymer used for packaging or by addition of various components from natural agents (bacteriocins, essential oils, natural extracts, etc.) to synthetic agents, both organic and inorganic (Ag, ZnO, TiO2 nanoparticles, synthetic antibiotics etc.). The general trend for the packaging evolution is from the inert and polluting plastic waste to the antimicrobial active, biodegradable or edible, biopolymer film packaging. Like in many domains this transition is an evolution rather than a revolution, and changes are coming in small steps. Changing the public perception and industry focus on the antimicrobial packaging solutions will enhance the shelf life and provide healthier food, thus diminishing the waste of agricultural resources, but will also reduce the plastic pollution generated by humankind as most new polymers used for packaging are from renewable sources and are biodegradable. Polysaccharides (like chitosan, cellulose and derivatives, starch etc.), lipids and proteins (from vegetal or animal origin), and some other specific biopolymers (like polylactic acid or polyvinyl alcohol) have been used as single component or in blends to obtain antimicrobial packaging materials. Where the package’s antimicrobial and antioxidant activities need a larger spectrum or a boost, certain active substances are embedded, encapsulated, coated, grafted into or onto the polymeric film. This review tries to cover the latest updates on the antimicrobial packaging, edible or not, using as support traditional and new polymers, with emphasis on natural compounds.
