“…[29] The process to make covalent grafting of active substances onto inert polymers starts with the functionalization of the polymeric substrate. Environmentally friendly methods (solvent-free), such as gamma-ionization radiation or cold plasma gas discharge, can be used to accomplish this step; subsequently the enriched surface with oxygen-containing groups is ready to bond with the active compounds, which can be added by dipping/immersion, spreading, or electrospinning [30][31][32][33].…”

“…The most efficient method, in respect to homogeneity of surface and thickness of deposited layer, to deposit chitosan into activated surface substrate of poly(lactic acid) (PLA) was by immersion, however electrospraying was the most versatile [33]. Moreover, coupling agents can also be used in the process (e.g., ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride or 1-carbonyldiimidazole, N-hydroxysuccinimide) [3,32,34]. Chitosan grafted onto a PLA surface enhanced the antibacterial and antifungal effect of the polymer, while also added antioxidant properties to the packaging material [33].…”

“…Coated PLA with chitosan also preserved the general aspect and properties of apple juice for a longer period of time (change in color or browning do not appear after 48 h storage) when compared to samples packaged in pristine PLA or in commercial plastic material (polyethylene terephthalate (PET)), in which the changes appeared after 24 h or 2 h, respectively [33]. Chitosan also enhanced antimicrobial properties of polyethylene (PE) when coated alone [34] or with vitamin E [32], demonstrating potential to be used either in food packaging or in medical applications.…”

Chitosan-based composites play an important role in food packaging applications and can be used either as films or as edible coatings. Due to their high costs and lower performance (i.e., lower barrier against water vapor, thermal, and mechanical properties) when compared to the traditional petroleum-based plastics, the use of such biopolymers in large-scale is still limited. Several approaches of chitosan composites in the packaging industry are emerging to overcome some of the disadvantages of pristine polymers. Thus, this work intends to present the current trends and the future challenges towards production and application of chitosan composites in the food packaging industry.

“…To alleviate these problems, smaller amounts of essential oils can be combined with other antimicrobial compounds. One of the intelligent approaches could be the combination of extracts with polysaccharides as a coating for films [19][20][21][22][23][24] in order to positively change their mechanical, optical or barrier properties and to introduce bioactive properties in a suitable way. The use of antioxidants in synergistic formulation with other biopolymers as nanoparticles, with enlarged contact area compared to conventional antioxidant agents, might allow for a reduction in the amount of active substances, which would act very efficiently while simultaneously reducing and/or avoiding the effect of active substances on the required properties of the base packaging material [25][26][27].…”

Polypropylene (PP) and polyethylene (PE) foils, previously activated by ultraviolet (UV)/ozone, were functionalized using chitosan-extract nanoparticle dispersions. A solution of macromolecular chitosan was applied onto foils as a first layer, followed by the deposition of various extracts encapsulated into chitosan nanoparticles, which were attached as an upper layer. Functionalized foils were analyzed from a bioactive point of view, i.e., regarding antimicrobial and antioxidant activity. Desorption kinetics were also studied. Moreover, barrier properties were examined, as the most important parameter influencing antimicrobial and antioxidant activity. Finally, all these properties were correlated with different surface parameters, determined previously, in order to understand if there is any direct correlation between surface elemental composition, surface charge, contact angle, or morphology and a specific bioactive property. It was shown that great bioactive properties were introduced due to the additive effect of antimicrobial chitosan and antioxidative plant extracts. Moreover, oxygen permeability decreased significantly, and the migration of polyphenols and chitosan from the foil surface was below the OML (overall migration limit), which is very important for food industry applications. Furthermore, surface properties of foils influence to some extent the desired bioactivity.

“…[20][21][22][23][24] Due to its great bioactive properties, chitosan may be an ideal potential substance for polyethylene coatings -in line with the active packaging concept. [25][26][27][28][29] Due to its bacteriostatic function, it prolongs the lag phase and, consequently, reduces the growth rate of microorganisms, thus extending the shelf-life of products and maintaining product quality and safety. 30,31 Although there are several contributions focusing on the use of chitosan in different structural forms or on its combination with other antimicrobial/antioxidant agents for food preservation, [30][31][32][33] there has been little work done on the use of complementary synergistic formulations of chitosan and pullulan.…”

Polyethylene (PE) material in the form of foils as conventional packaging material was functionalised with polysaccharide pullulan and an additional layer of chitosan macromolecular solution. In this study, the best concentration of pullulan (10%, 20% or 30%) was determined with the objective of improving the barrier properties of conventional PE food packaging material. As additional layer, a chitosan macromolecular solution was adsorbed to the material in order to endow it with antimicrobial activity. In this way, a functional composite material was developed, which can find potential application as active packaging, to offer prolonged shelf-life to packaged food. The functionalized PE material was analysed from the physico-chemical point of view (gravimetric analysis, goniometry, FTIR spectroscopy, standard test for oxygen permeability, SEM analysis). Moreover, antimicrobial testing of the foils was done and the desorption of both polysaccharides from the PE surface was evaluated. The latter properties are essential when evaluating the practical value of active packaging.
