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.

“…The efficiency of packed cheese into gelatine-based nanocomposite containing chitosan nanofiber and ZnO nanoparticles over a period of 12 days was examined against the total bacterial counts (TBC) and it was shown that after the storage period, the bacterial count slightly decreased in comparison with the control chitosan packed cheese (2.4 log CFU/g); 1.93 ± 0.15 and 1.66 ± 0.15 log CFU/g in CHINF and ZnONPs, respectively [31]. Other study examined the TBC value of skimmed milk acid coagulated cheese packed in chitosan and chitosan coated with titanium dioxide nanoparticles (TiO2 -NPs) stored for 25 days at 4 0 C. Based on their results the number of TBC in chitosan packed cheese in the last day was 8.3 ± 0.1 log CFU/g and in the cheese packed in chitosan coated with 3.0 % TiO2 -NPs the TBC count was 7.5 ± 0.33 log CFU/g [98]. Cheese samples packed in linear low density polyethylene (LLDPE) and antimicrobial packaging films, such as furcellaran-whey protein isolate (FUR/WPI), furcellaran-whey protein isolate incorporated with yerba mate extract (FUR/WPI + YM) and with white tea extract (FUR/WPI + WT), were stored at 4 0 C for 3 weeks.…”

“…The antimicrobial activities of the prepared nanomaterials and its nanocomposites were studied using disc agar plate method was employed to evaluate the antimicrobial activity of the prepared nanocomposites [3,21]. The antimicrobial activities of 0.5 cm diameter of nanocomposites disc (5 mm) were placed on agar plates seeded with test microbes and incubated for 24 hrs at the appropriate temperature of each test organism.…”

This study aims to synthesis and characterize of poly (methyl methacrylate) nanocomposites that based on methyl methacrylate monomer (MMA) and zinc oxide nanoparticles (ZnO-NPs), namely PMMA/ZnO nanocomposite via in-situ emulsion polymerization of MMA monomer using potassium persulphate (PPS) as initiator. ZnO-NPs were firstly prepared through hydrothermal method. The prepared ZnO-NPs were investigated by X-Ray diffraction pattern (XRD), Fourier transform infrared (FT-IR) and transmission electron microscope (TEM). PMMA/ZnO nanocomposites were prepared via emulsion polymerization using different concentrations of ZnO-NPs (2%, 4%, 8% and 12%) based on monomer concentration. Furthermore, PMMA/ZnO nanocomposites were studied using FT-IR, TEM, XRD, UV/Vis spectroscopy and thermal gravimetric analysis (TGA). The fabricated poly (methyl methacrylate) nanocomposites display good morphological, thermal properties and antibacterial activity than pure PMMA. Additionally, the PMMA nanocomposites display respectable antimicrobial activity against gram positive (Staphylococcus aureus) bacteria, gram negative (Pseudomonas aeruginosa) bacteria and yeast (Candida albicans). Additionally, the PMMA nanocomposites can be used as good materials for antibacterial packaging applications.
