“…According to DTGA curves, upon addition of nanoperlite T max is decreased as the nanoperlite increases the amorphous phase, while due to the silane treatment of nanoperlite the interaction of polymer and these nanoparticles show an increasing trend for T max . Finally, the ash content for the nanocomposites is increased in both LN and LTN nanocomposites from 2.28 to 8.15 and 8.57% upon addition of nanoperlite.…”

Nanocomposites films based on low‐density polyethylene (LDPE) and different compositions of treated and untreated nanoperlite were prepared via melt mixing of the ingredients on a corotating twin‐screw extruder and then film blowing the nanocomposites. The physical dispersion of the nanocomposites is confirmed using Fourier transform infrared‐attenuated total reflectance (FTIR‐ATR) method. According to the thermal studies, the nanocomposites with untreated nanoperlite showing higher melting temperature and crystallinity, while their thermal stability is lower than nanocomposites with treated nanoperlite. The thermal and FTIR‐ATR studies also revealed the ethylene absorption of the nanocomposites. According to the surface energy results, the treatment of the nanoparticles completely changes the surface behavior and hydrophobicity of the films. Finally, peel color index and field study observations showed that increase in nanoperlite will increase the shelf life of the fruits; however, the nanocomposite with 6% untreated nanoperlite is the best choice for the packaging applications.

“…At the same pH, the water solubility was measured for all the samples. The water solubility of the SM0 film is relatively 29.42% and the addition of nanoclay the water resistance of these nanocomposite films is increased which could be due to the hydrophobic nature of Cloisite 15A [9]. As the hydrophobicity of the films increased, the moisture content shows the same trend and is increased upon addition of the nanoclay.…”

This work aimed to develop a nano edible antimicrobial coating based on Salvia macrosiphon seed mucilage (SSM) and nanoclay, incorporated with glycerol to evaluate its physical properties. Upon addition of 2% nanoclay physical and mechanical properties were considerably improved and the composite films showed the lowest water vapor permeability (WVP), as well as highest elongation at break and tensile strength, which makes these films great alternatives for food packaging. While E. coli and S. aureus were significantly inhibited by this antimicrobial films. Results indicated that this novel antimicrobial edible film could have great potential for responsive packaging applications.

The polypropylene with load of reinforcement of curauá fiber (PP-curauá) is a compound developed to be applied in the process of injection of automotive plastic parts. Polypropylene composites reinforced with mineral fillers (talc) or glass fibers have been widely applied in this segment. However, natural fibers are an important alternative considering the aspects of sustainability, recyclability, abundance and low cost, when compared with glass fibers, and industrial talc. This study was prompted by the growing need for materials that meet the constant cycles of use, disposal and reuse, and avoid the harmful effects on the environment. The mechanical properties of a curaua fiber and polypropylene-based ecocomposite reprocessed one, three and five times were assessed, since reprocessing is known to change the strength of these materials. Pure polypropylene (0%) and ecocomposites with 10 and 30 wt% of fiber were submitted to tensile and three-point bending tests. The results showed that polypropylene ecocomposites with 30% curaua fibers exhibited a higher modulus of elasticity. Moreover, reprocessing did not significantly affect the ecocomposite properties, demonstrating their viability for reuse.
