There is a strong drive in industry for packaging solutions that contribute to sustainable development by targeting a circular economy, which pivots around the recyclability of the packaging materials. The aim is to reduce traditional plastic consumption and achieve high recycling efficiency while maintaining the desired barrier and mechanical properties. In this domain, packaging materials in the form of polymer nanocomposites (PNCs) can offer the desired functionalities and can be a potential replacement for complex multilayered polymer structures. There has been an increasing interest in nanocomposites for food packaging applications, with a five-fold rise in the number of published articles during the period 2010–2019. The barrier, mechanical, and thermal properties of the polymers can be significantly improved by incorporating low concentrations of nanofillers. Furthermore, antimicrobial and antioxidant properties can be introduced, which are very relevant for food packaging applications. In this review, we will present an overview of the nanocomposite materials for food packaging applications. We will briefly discuss different nanofillers, methods to incorporate them in the polymer matrix, and surface treatments, with a special focus on the barrier, antimicrobial, and antioxidant properties. On the practical side migration issues, consumer acceptability, recyclability, and toxicity aspects will also be discussed.

Significant Prolongation

Food packaging plays an active role in the environment/packaging/food system, and new solutions take into account new concepts of smart, active, and/or eco-friendly food packaging materials. On this point of view, the active packaging system should be capable of interacting with the food, for instance by the release of active molecules that will provide protection against microbial spoilage, and simultaneously be ‘natural’. A full exploitation of the antimicrobial and antioxidant properties of propolis, in order to achieve a significant prolongation of the shelf-life, can meet these needs. Moreover, fast methods able for classifying, sorting, and identifying the quality and the stability characteristics associated with the different materials are requested along the food chain in order to validate their properties. This study aimed the identification of bioactive compounds from Italian propolis in smart packaging materials by applying the aquaphotomics approach. The Aquagrams results highlighted that the absorption differences at 1410 nm are able to identify the paper sheets obtained by the incorporation of the active compounds. A second Aquagrams plot was built up for sheets measured on polythene layer. Results showed different water patterns at 1438, 1440, and from 1474 to 1518 nm. These data confirm that the water absorption in NIR range can be affected by the presence of chemical groups derived from the active compounds of propolis, which are able to interact with water spectral response.

Concerns about environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as consumer demand for high-quality food products have led to increased interest in the development of biodegradable packaging materials using annually renewable natural biopolymers. Inherent shortcomings of natural polymer-based packaging materials such as low mechanical properties and low barrier properties can be recovered by applying nanocomposite technology. Polymer nanocomposites, especially natural biopolymer-layered silicate nanocomposites, exhibit markedly improved packaging properties due to large nanoparticle surface area and their significant aspect ratios. Additionally, natural biopolymer is susceptible to microorganisms, resulting in good biodegradability, which is one of the most promising aspects of its incorporation in packaging materials and industries. The present review article explains the various categories of nanoclay and bio-based polymer-based composites with particular regard to their application as packaging materials. It also gives an overview of the most recent advances and emerging new aspects of nanotechnology for development of composites for environmentally compatible food packaging materials.

Essential oils prevent superbug formation, which is mainly caused by the continuous use of synthetic drugs. This is a significant threat to health, the environment, and food safety. Plant extracts in the form of essential oils are good enough to destroy pests and fight bacterial infections in animals and humans. In this review article, different essential oils containing polymeric nanofibers fabricated by electrospinning are reviewed. These nanofibers containing essential oils have shown applications in biomedical applications and as food-packaging materials. This approach of delivering essential oils in nanoformulations has attracted considerable attention in the scientific community due to its low price, a considerable ratio of surface area to volume, versatility, and high yield. It is observed that the resulting nanofibers possess antimicrobial, anti-inflammatory, and antioxidant properties. Therefore, they can reduce the use of toxic synthetic drugs that are utilized in the cosmetics, medicine, and food industries. These nanofibers increase barrier properties against light, oxygen, and heat, thereby protecting and preserving the food from oxidative damage. Moreover, the nanofibers discussed are introduced with naturally derived chemical compounds in a controlled manner, which simultaneously prevents their degradation. The nanofibers loaded with different essential oils demonstrate an ability to increase the shelf-life of various food products while using them as active packaging materials.

Recycled Plastics

The European strategy for plastics, as part of the EU’s circular economy action plan, should support the reduction in plastic waste. One key element in this action plan is the improvement of the economics and quality of recycled plastics. In addition, an important goal is that by 2030, all plastics packaging placed on the EU market must either be reusable or can be recycled in a cost-effective manner. This means that, at the end, a closed-loop recycling of food packaging materials should be established. However, the use of recyclates must not result in less severe preventive consumer protection of food packaging materials. This may lead to a conservative evaluation of authorities on post-consumer recyclates in food packaging applications. On the other hand, over-conservatism might over-protect the consumer and generate insurmountable barriers to the application of post-consumer recyclates for food packaging and, hence, counteract the targets of circular economy. The objective of this review is to provide an insight into the evaluation of post-consumer recyclates applied in direct contact to food. Safety assessment criteria as developed by the European Food Safety Authority EFSA will be presented, explained, and critically discussed.

Mechanical And Thermal Properties

Due to the high demand of the use of food packaging in the present day, the waste from the material disposal has become a problem of high environmental impact. In this perspective, biodegradable polymers can represent a viable alternative as they degrade after their disposal, thus reducing their environmental impact. The poly(lactic acid) or polylactide is a biodegradable, biocompatible, and compostable polymer, being considered by many authors as one of the most promising biopolymers in industrial applications. However, its low thermal and mechanical properties make it an unfeasible option to replace synthetic polymers. Consequently, polymer nanocomposites containing carbon nanoparticles are products of relevant interest currently, mainly due to the thermal, mechanical, electrical, and optical properties these materials can present. Therefore, carbon nanoparticles (carbon nanotubes, graphene, and fullerene) modified with octadecylamine in their isolated state and in ternary systems in concentrations of 0.01%, 0.03%, and 0.09% were obtained from poly(lactic acid) polymer nanocomposites. After obtaining them, these systems were analyzed by TGA, DSC, FTIR, XRD, SEM, DMA, and NMR techniques. The presence of the octadecylamine modified carbon nanoparticles was able to increase the thermal and mechanical resistance of the poly(lactic acid) matrix. The systems with 0.03% of the nanostructures showed better results in both analyses. In the system with 0.09%, agglomeration occurred, and in ternary systems, the application of these particles results in a greater impact on the molecular mobility exhibiting a synergistic effect that may come from a better dispersion.

Background: Recently, numerous studies on packaging nanomaterials for foods underline the significant function of nanofillers in the manufacturing of innovative nanocomposites based on polymer or biopolymer matrices. It is evident in the literature that nanofillers exhibit effective characteristics such as antimicrobial potential, barrier, mechanical, and thermal properties. However, the exact mechanisms regulating the occurrence of the antimicrobial activity of nanofillers are only hypothesized, the literature containing controversies on the mechanisms of nanofiller-induced toxicity. Objective and approach: The objective of this review is to highlight several types of nanofillers, especially inorganic nanofillers that can be used along different polymers or biopolymers to form innovative food packaging materials. The antimicrobial potential of metal-based nanofillers is also discussed in the second part of the review. Key findings and conclusions: Even though numerous reports on polymer or biopolymer nanomaterial applications in food packaging are available, their purpose is not aimed at in this article, and a smaller number of reviews approaches food packaging nanomaterials in this way. It is expected that the information contained in this paper will complement previous reports, and open new vistas for explorers to apply nanofillers in the functional food packaging area.
