Petroleum-based plastics were widely used as packaging materials. However, plastic materials were not reusable and biodegradable, causing a severe negative impact on the environment. Edible films can be a suitable alternative to plastic films, particularly in food packaging. This research work prepared edible films containing blends of cornstarch, arrowroot powder, refined wheat flour, vinegar, and glycerol. Arrowroot powder added strength and nutritional value to the films. Glycerol, as a plasticiser, improved the flexibility of films. The combination of vinegar and glycerol increased the film’s strength. The characteristic properties of prepared films, like thickness, bursting strength, moisture content, transparency, water-solubility, water vapour permeability, tensile strength, elongation, and Young’s modulus, were analysed. The thermal stability of the films was evaluated by thermogravimetric analysis. The films were characterised by FTIR spectroscopy, and their surface morphology was analysed by scanning electron microscopy. The prepared films exhibited excellent properties suitable for food packaging.

“…However, several studies have been documented that, the decrease of tensile strength in the bioplastic as a response to the increase of plasticizers concentration [39][40][41]. Bioplastic based on arrowroot starch with glycerol plasticizer and ZnO fillers produced tensile strength of 5, 9966 MPa [42]. The difference in the results could be due to the method of bioplastic preparation, nature of filler, and matrix used [33].…”

The objective of this research was to investigate the mechanical, physical and antibacterial activities and biodegradability properties of bioplastics from polylactic acid (PLA) and corncob fibers (CF). The bioplastics were prepared by mixing PLA and CF at different ratios (100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 % w:w) in the internal mixer and molding was done by using the hot-compressing molding method. The results demonstrated the decrease in tensile strength and elongation at break with increased in CF. Young’s modulus was found to be highest in the 70 %PLA: 30 %CF bioplastic, however, it decreased when the CF was increased. The hardness and water absorption were dependent on CF concentration. SEM analysis revealed the well dispersion of CF in PLA matrix. PLA matrix and increasing of CF induced in CF agglomeration. To develop PLA/CE plastic for antibacterial food packaging application, its antibacterial activity was conducted. The antibacterial determination revealed that 70 %PLA: 30 %CF containing 2 % TiO2 bioplastic exhibited the highest inhibition against E. Coli, S. aureus and B. subtilis. The results obtained from this research indicate that the bioplastics prepared from polylactic acid and corncob fibers is biodegradable bioplastics and can be used as alternate synthetic plastics. The bioplastic with 2 %TiO2 added can be utilized potentially for expected antibacterial food packaging. HIGHLIGHTS The bioplastics prepared from polylactic acid and corncob fibers (PLA/CF) is a biodegradable bioplastic PLA/CF bioplastic with the addition of 1 % TiO2 possesses antibacterial property Corncob fibers decrease tensile strength, elongation at break and Young’s modulus of the PLA/CF bioplastic Corncob fibers increase the hardness and water absorption of the PLA/CF bioplastic Increasing concentration of corncob fibers causes the agglomeration of corncob fibers in the PLA/CF bioplastic GRAPHICAL ABSTRACT
