“…Equation (6) indicates that the permeation process involves an initial transient condition where the j(t) value increases with time t which is followed by stationary transport conditions where the permeation flux j(t) assumes the constant value: j(t → ∞) = J = (D•Π)/L•P HPS = ϕ/L•P HPS . The quantity ϕ = D•Π is called the gas permeability.…”

“…The synthesis of biopolymer nanocomposites containing inorganic nanoparticles (such as nano-clay or montmorillonite), metal and metal oxide nanoparticles (such as Ag, ZnO and CuO) and bio-additives (such as plant extracts, chitosan and cellulose) is a route often employed to improve the operative performance of biopolymers [5]. PLA-based bio-nanocomposites with enhanced gas barrier properties have been prepared adding nanoparticles such as CaCO 3 [6] and Cu:ZnO powders functionalized with Ag nanoparticles [7]. Cellulose fibers have been found to increase the barrier properties of thermoplastic biopolymer films against water [8], water vapor [9], air and oxygen [10].…”

According to the European Bioplastics association, in 2017, the so-called bioplastics represented only 2.06 million tons of the 320 million tons of plastics produced annually [1]. The global production capacity is expected to increase up to 2.62 million tons in 2023. This growth is pushed by the demand of more sophisticated biopolymers, new applications and products. From packaging, agriculture, consumer electronics, textile to automotive, bioplastics are used in an increasing number of applications. In fact, biopolymers offer a number of additional advantages if compared to conventional plastics, such as a reduced carbon footprint and additional waste management options. Among bio-based and biodegradable plastics, polylactic acid (PLA) is one of the most interesting ones due to their good mechanical properties, good workability, excellent barrier properties. Therefore, it is a good candidate for the replacement of polystyrene (PS), polypropylene (PP), and acrylonitrile butadiene styrene (ABS) in many applications. However, PLA presents some weak points mainly represented by its low ductility, poor toughness, low glass transition temperature, high sensitivity to moisture and relatively low gas barrier, that limit its use in packaging applications [2, 3]. Indeed, the main

“…Although a large proportion is reincorporated into poultry feed, these inorganic elements can be considered for incorporation into polymers and biopolymers for packaging [62]. These carbonates can not only be considered as fillers, but also have barrier properties to oxygen and to light and UVs, as shown by Aframehr et al [63], when incorporated into PLA. The addition of eggshell nanoparticles to a bioplastic (PLA, PHBV, etc.)…”

The agro‐food industry cannot today do without packaging to preserve and above all market its products. Plastic materials coming mainly from petrochemicals have taken a predominant place in the food packaging sector. They have become indispensable in many sectors, from fresh to frozen products, from meat and dairy products to fruit and vegetables or almost‐ready meals. Plastics are cheap, their lightness reduces transport costs, and their convenience is fundamental for out‐of‐home catering. However, plastics pose serious end‐of‐life issues. The development of materials that are more respectful of the consumer and the environment has become a major issue. In addition, the agro‐food industries generate significant quantities of waste or by‐products that are poorly or not at all recovered. However, these contain constituents that can be extracted or transformed to be compatible with packaging uses. Many molecules from waste materials are of particular interest for the development of active packaging such as biopolymers, bioactive agents, inorganic compounds, fibers, or nano‐ and micro‐objects. Providing bioactive functions such as antioxidants or antimicrobials can extend the shelf life of food while reducing the sophistication of plastic materials and thus improving their recycling. This article summarizes the main materials and constituents that can be recovered from waste and illustrates through several examples what could be the applications of such new, sustainable, and active packaging.

“…Traditionally, most plastic packaging materials are made from petroleum-based polymers, mainly containing the commodity polystyrene (PS) and polyethylene (PE), which are recognized as not being environmentally friendly. With the development of new polymer materials, the biodegradable polymer-based plastics can provide a viable alternative, such as PVA [ 130 , 131 , 132 , 133 , 134 ], polylactic acid (PLA) [ 135 , 136 , 137 , 138 , 139 ], poly(3-hydroxybutyrate) (PHB) [ 140 , 141 ] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) [ 78 , 142 ] and their biopolymer blends.…”

“…Among the various biopolymers investigated, PLA exhibits key properties, including biodegradability, renewability and superior mechanical properties, crystallinity and process ability [ 102 , 145 ]. Aframehr et al investigated the impact of calcium carbonate (CaCO 3 ) nanoparticles on the biodegradability and barrier properties of PLA [ 137 ]. The results showed that the barrier properties were increased by loading CaCO 3 -NPs increasing to 5 wt%.…”

The increasing demand for high food quality and safety, and concerns of environment sustainable development have been encouraging researchers in the food industry to exploit the robust and green biodegradable nanocomposites, which provide new opportunities and challenges for the development of nanomaterials in the food industry. This review paper aims at summarizing the recent three years of research findings on the new development of nanomaterials for food packaging. Two categories of nanomaterials (i.e., inorganic and organic) are included. The synthetic methods, physical and chemical properties, biological activity, and applications in food systems and safety assessments of each nanomaterial are presented. This review also highlights the possible mechanisms of antimicrobial activity against bacteria of certain active nanomaterials and their health concerns. It concludes with an outlook of the nanomaterials functionalized in food packaging.
