“…Nordin et al [36] also reported a reduction in tensile strength of bioplastic film as the amount of added filler increased, which was attributed to phase separation, poor particle distribution, and agglomeration of particles. The tensile strength reported in this study for silica-based bioplastic film was lower than that reported by Aji et al [37]. The difference in the results could be due to the method of bioplastic preparation, nature of filler, and matrix used.…”

The adverse environmental effects of petroleum-based packaging plastics have necessitated the need for eco-friendly bioplastics. Most bioplastics are starch-based and are not without drawbacks, hence there is the need for their properties to be improved. In this study, the effect of varying concentrations of dialdehyde starch and silica solutions on the physical, mechanical, biodegradable, surface topology, and thermal properties of the bioplastic films was examined. The additive concentrations were varied from 60 to 100%. The bioplastic films produced with dialdehyde starch solution recorded better moisture content (6.62–11.85%), bioplastic film solubility (4.23–7.90%), and tensile strength (1.63–3.06 MPa), against (11.24–14.26%), (7.77–19.27%) and (0.53–0.73 MPa) respectively for bioplastic films produced with silica solution. The atomic force microscopy analysis; root-mean-square roughness, kurtosis, and skewness revealed better miscibility and compatibility between the starch matrix and the dialdehyde solution than between the starch matrix and the silica solution. Bioplastic with added dialdehyde starch solution has better tensile strength and long biodegradability than that with silica solution. The research has demonstrated that bioplastic film produced with starch and dialdehyde starch solution has better properties than the one produced with starch and silica solution. The properties evaluation results of the bioplastic films thus demonstrated their aptness for food packaging applications. Graphic abstract

“…A larger SD indicates a larger spread of the data distribution, which may be affected by the presence of outliers in the data. The increment in TS occurs due to the formation of strong hydrogen bonds between the nanoparticles and the hydroxyl groups in the film matrix [ 22 ] and the van der Waals force which strengthens the intermolecular forces between nanoparticles and carrageenan [ 21 ]. The IC/SiO 2 –ZnO 1:3 film had the greatest TS.…”

“…The concentration of SiO 2 remained the same in all the formulas, referring to Aji et al. [ 21 ] and Rane et al. [ 23 ], which found that the concentration of SiO 2 nanoparticles that imparts the best film properties was 0.5% w/w carrageenan.…”

“…Independent application of either SiO 2 or ZnO nanoparticles (NPs) as fillers in the carrageenan-based film has been reported in improving the film properties in previous studies [ 1 , 20 , 21 , 22 , 23 ]. Among them, the utilization of semi-refined carrageenan to produce bio-nanocomposite film is more interesting with considerably low production cost compare to the refined form which is relatively expensive.…”

“…Moreover, there were only limited studies on developing bio-nanocomposite film with the semi-refined iota carrageenan (SRIC) as the main film matrix. Previous studies showed the incorporation of SiO 2 NPs and ZnO NPs separately enhanced the properties of SRIC films [ 1 , 21 ]. Also, recent study showed that SiO 2 NPs as fillers provided antimicrobial functionality [ 24 ].…”

This paper reports the incorporation of SiO 2 –ZnO nanoparticles (NPs) into semi-refined iota carrageenan-based (SRIC) film as active food packaging. The dispersion of the nanoparticles was performed using a bead milling method and the films were prepared using the solution casting method. The incorporation of SiO 2 –ZnO NPs into SRIC films aims to provide multifunctional food packaging with enhanced water vapor barrier properties, UV-screening, and antimicrobial activity. The effect of the incorporation of SiO 2 NPs, ZnO NPs, and the mixtures of SiO 2 –ZnO NPs varied in SiO 2 /ZnO ratios (SiO 2 –ZnO 1:1, 1:2, and 1:3) were investigated. The results showed that the tensile strength, water vapor barrier performance, UV-screening, and antimicrobial activity of the SRIC film were increased by the addition of either SiO 2 or ZnO NPs alone. Interestingly, when the mixtures of SiO 2 –ZnO were incorporated, more significant improvement was observed. Also, the bio-degradability and solubility of all the SRIC films were confirmed. It was concluded that the SiO 2 –ZnO NPs incorporated into SRIC film provided multifunctional activities and acted as a promising active food packaging material.

The simultaneous extraction of cellulose fiber and crystal biogenic silica from the same rice husk and evaluation in cellulose‐based composite bioplastic films

Bioplastics are environmental‐friendly materials that have been essentially required to reduce global pollution resulting from the accumulation of conventional plastics. The current study was focused on simultaneous extraction of cellulose fiber and crystal biogenic silica from the same rice husks and preparation of silica‐reinforced cellulose‐based composite bioplastic films via casting method to evaluate in packaging applications. Herein, ZnCl2 was utilized as a solvent for the extracted cellulose fiber for the first time. As the silica content increased, barrier properties of bioplastic films increased. The highest tensile strength value in bioplastic films was obtained at 1347 kN/m2 with 2% weight silica content. The biodegradability of bioplastic films in the soil after 21 days varied between 25.5% and 55.7%, which values were significantly higher than conventional plastics. After evaluating these properties, we strongly believe that composite bioplastic films have a high potential to be utilized as green packaging material.
