“…Same authors used melanin nanoparticles from the sepia ink to synthetize antioxidant agar-based films with enhanced hydrophobicity, UV-blocking, water vapor barrier and mechanical properties [266]. Moreover, in situ mineralization of Cu-and Zn-nanoparticles into agar matrix showed high UV-blocking effect, with excellent antimicrobial activity toward different bacteria and fungi [19,267,268]. Generally, it was shown, as similar to alginate composites, that agar-starch-based edible films possessed very good mechanical properties for food packaging development [269,270].…”

The use of polysaccharide-based materials presents an eco-friendly technological solution, by reducing dependence on fossil resources while reducing a product's carbon footprint, when compared to conventional plastic packaging materials. This review discusses the potential of polysaccharides as a raw material to produce multifunctional materials for food packaging applications. The covered areas include the recent innovations and properties of the polysaccharide-based materials. Emphasis is given to hemicelluloses, marine polysaccharides, and bacterial exopolysaccharides and their potential application in the latest trends of food packaging materials, including edible coatings, intelligent films, and thermo-insulated aerogel packaging.

“…In general, the higher the TS of a film, the lower its E , and vice versa . This happened in the gluten film, which presented greater elongation to rupture than the others; however, its tensile strength was not as good as that of the hake protein isolate film.…”

“…58 The mechanical properties of tensile strength and elongation to rupture are important because packaging materials must provide sufficient mechanical strength to maintain their integrity during In general, the higher the TS of a film, the lower its E, and vice versa. 60 This happened in the gluten film, which presented greater elongation to rupture than the others; however, its tensile strength was not as good as that of the hake protein isolate film. Gennadios et al 61 found values very close to those obtained in the present study when evaluated the mechanical properties of wheat gluten films.…”

Bilayer films propose to combine the characteristics of different individual polymer sources in a single structure, aiming to improve the properties of the films obtained. The objective of this study was to develop and characterize bilayer films prepared from individual films of zein, wheat gluten, and protein isolate from hake (Cynoscion guatacupa), and evaluate the biodegradability of these polymers. Through the casting technique, individual films and bilayers were prepared. The hake proteins isolate films, as well as the bilayers hake protein isolate/zein and hake protein isolate/wheat gluten (BI PI/WG) showed higher tensile strength, while wheat gluten films presented greater elongation at rupture and lower solubility. In addition to having good tensile strength, BI PI/WG presented the best elongation. All films and bilayers reached melting and glass transition temperatures above 100°C. Electromicrographs of the films presented an irregular surface with pores and grooves, being less pronounced in BI PI/WG. In the bilayers, it was not necessary to use any type of adhesive to form a single structure. Films and bilayers showed total biodegradability in 40 days, with the exception of the individual zein film. BI PI/WG proved to be the most suitable for the development of food packaging materials. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46721.

“…This is further explained in Chemical Properties. Similar interactions had led to improvements in mechanical properties by incorporating different fillers such as nanoclay and MgO, which had facilitated the effective stress transfer from the matrix to the filler as a result of superior filler-matrix interaction [6,24,39]. Plots related to σ and E of both composite types followed similar patterns where there is an increasing trend from 0 to 0.25 (w/w%) and decreasing trend after that until 1 (w/w%).…”

In this study, chitosan nanocomposite thin films were successfully fabricated by incorporating hematite nanoparticles (HNPs) and akaganeite nanoparticles (ANPs) as reinforcing fillers using the solution casting method. HNPs and ANPs were synthesized via a urea-assisted synthesis route using naturally occurring ferruginous laterites. Scanning electron microscopic (SEM) images indicated the spherical to subhexagonal morphology of the HNPs and rice-like morphology of the ANPs. X-ray diffractograms indicate the crystalline structure of iron oxides as hematite and akaganeite. Tensile tests were carried out to evaluate the mechanical properties of the nanocomposite films where maximum tensile stress of the chitosan/HNP composites was improved as high as 35.7% while chitosan/ANP composites indicated 43.5%. Thermal decomposition curves obtained by thermogravimetric analysis (TGA) indicate that the thermal stability of the nanocomposites has improved remarkably compared to neat chitosan films. Furthermore, these nanocomposites exhibited excellent UV barrier properties as identified by UV-visible spectrometry. Fourier-transform infrared (FTIR) spectroscopic results are evident in the presence of Fe-O bond in the wavenumber around 480-500 cm -1 , and the result also indicated that the nanofillers interact with the chitosan matrix via hydrogen bonding, which enhanced the physical properties of the nanocomposites. Incorporation of iron oxide nanoparticle varieties into chitosan has led to improvements of certain physical and chemical properties, which make chitosan a promising material for packaging applications.
