“…Protein, starch, cellulose, PLA-based nanocomposites are the ones that were separately reviewed earlier and compared, guaranteeing barrier performances and physical packaging integrity. Taken together, it seems that industrial usage of polymer blends, multilayer systems, natural biopolymers with chemical modifications, coatings, and composites can improve the features mentioned above [68,174,175].…”

“…Regarding this aim, a wide array of studies have shown that the incorporation of NPsor generally nanofillers extracted from organic or inorganic sources (mainly polysaccharide or protein with animal or plant-based with strong reinforcing effects)-into packaging materials like various polymers used in food packaging industries, can produce polymeric nanocomposites with high barrier properties against gases, water vapors and, etc., offering qualified food with prolonged shelf life [65][66][67][68].…”

“…Increasing the path length or blocking the passage of oxygen gas in the polymer by various particles is a new approach that has become one of the most important and effective pathways. There are several strategies for making improved barrier properties in polymers (like bioplastics) used for food packaging due to refraining from the migration of oxygen, carbon dioxide, anhydride, aroma, flavor, and water vapor to the ingredients of food, eventuating to make them as the most sustainable biopolymers [68,174,175]. Results of several studies proposed nanoscale size fillers like MMT and kaolinite clay.…”

Over the past decade, there has been an increasing demand for “ready-to-cook” and “ready-to-eat” foods, encouraging food producers, food suppliers, and food scientists to package foods with minimal processing and loss of nutrients during food processing. Following the increasing trend in the customer’s demands for minimally processed foodstuffs, this underscores the importance of promising interests toward industrial applications of novel and practical approaches in food. Along with substantial progress in the emergence of “nanoscience”, which has turned into the call of the century, the efficacy of conventional packaging has faded away. Accordingly, there is a wide range of new types of packaging, including electronic packaging machines, flexible packaging, sterile packaging, metal containers, aluminum foil, and flexographic printing. Hence, it has been demonstrated that these novel approaches can economically improve food safety and quality, decrease the microbial load of foodborne pathogens, and reduce food spoilage. This review study provides a comprehensive overview of the most common chemical or natural nanocomposites used in food packaging that can extend food shelf life, safety and quality. Finally, we discuss applying materials in the production of active and intelligent food packaging nanocomposite, synthesis of nanomaterial, and their effects on human health.

A series of coatings which applied for improving the oxygen barrier property of polyethylene terephthalate (PET) film were prepared based on the copolymerization of methyl methacrylate, methyl acrylate, diallyl maleate, and maleic acid (MA). The chemical structures of the coatings were characterized by Fourier Transform Infrared spectrometer. The curing behavior was analyzed by differential scanning calorimetry. The oxygen permeability (Po 2 ) was measured by gas permeability tester. The molecular weight was investigated by gel permeation chromatography (GPC). Po 2 is inversely proportional to the oxygen barrier property that the decrease of Po 2 indicates the improvement of oxygen barrier property. The coating containing inter-chain cross-linking structure formed by the dehydration of carboxylic acid improves the oxygen barrier property of PET film greatly. With the increasing content of MA, the oxygen barrier capability of coated PET film is enhanced according to the Po 2 decreasing from 1.450 to 0.8956. The Po 2 of coated PET film is minimized by selecting N-methyl pyrrolidone as solvent for polymerization. The GPC results indicate that the oxygen barrier of novel coated PET film can be obtained when the weight average molecular weight (Mw) is up to the stipulated value.

“…For this, nanotechnology has become of great importance in food packaging research. Many PET nanomaterials have been developed [8][9][10][11][12] but, very few of them have tried or succeeded industrially producing these nanocomposites [13]. Between clay nanomaterials, the one most studied with PET is montmorillonite [8][9][10][11], a magnesium and aluminum silicate mineral.…”

Shelf Life of Fresh Sliced Sea Bream Pack in PET Nanocomposite Trays

Spoilage of fish due to microbiological activity is one of the biggest problems found by producers to take fresh fish products to customers. It is necessary packaging improvements to be able to increase fish shelf life and, thus, be able to travel further and to keep product freshness longer at customer’s houses. In the present work, a new material is developed for fish packaging in modified atmosphere (MAP). This material is poly(ethylene terephathalate) (PET) extruded with a polyamide (PA) nanocomposite containing nanosepiolite. Here, it is shown the production procedure from laboratory to industrial scale. Permeability to oxygen and impact mechanical properties results are shown for different samples, both at laboratory and industrial processes. At the end, a material composition is chosen to produce the finale tray which will contain the sliced sea bream. Microbiological analysis is done over the packed fish, resulting is a lower microbiological count compared to a PET control sample. This means that shelf life of pack sea bream could increase from 2–4 to 7–9 days, which is very important for both producers and customers. On the other hand, trays obtained comply with European regulations in food contact materials (FCM) and, overall, they are suitable for food packaging materials.
