“…The slow degradation rate of all bioplastic films produced with dialdehyde starch solution could be linked to the low moisture content and solubility. This is because bioplastic needs a certain amount of moisture to swell and then burst before degradation takes place [38]. Besides, the increase in degradation as the amount of silica solution added increases could be due to the formation of agglomerates of particle creating pores that permit the passage of air and water, leading to swelling and bursting of the bioplastics.…”

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

Natural based film have been studied as a possible replacement for the conventional films because it can be developed from natural sources. The aim of this study is to investigate the effect of acetylation contact time to the physical and mechanical properties of the jackfruit rind based cellulose acetate film. Acetylation of jackfruit rind based cellulose was studied and samples with different degree of substitution were obtained as a function of contact time from 1 hour to 24 hours. The products were characterized by saponification reaction. In this study, saponifcation reaction showed that, more hydroxyl group were substituted with acetyl groups as the contact time of acetylation increased. The Cellulose Acetate (CA) had been mixed in the gelatine matrix film. The addition of jackfruit rind based CA showed that the moisture uptake and solubility of the film decreased compared to Cellulose/Gelatine composite film. This is because acetyl groups are more hydrophobic than hydroxyl groups thus reducing the hydophilic nature of cellulose. Additionally, from the tensile test, it was proven that the film with CA of 24 hours contact time exhibits the highest tensile strength.
