Here, new film materials (oak tree acorn starch-clove essential oil (CEO)-halloysite nanotube (HNT) films) were prepared for the first time using naturally abundant oak tree acorns and halloysite nanotube clay minerals, and a natural product (clove essential oil, CEO). The characterization of the fabricated film materials was performed by FTIR, opacity, water contact angle, color, water vapor permeability, mechanical analysis and thermal gravimetric analysis measurements. The presence of HNT or CEO within starch film matrix increased the opacity value of starch film with increasing HNT or CEO concentration. The improved water vapor barrier properties of starch film were achieved by using HNT and CEO in the film formulation. By using 5% HNT into the starch film matrix, the improvements of 87.5% in the maximum tensile stress and 108% in the Young's modulus of the starch film were obtained. In the preparation of starch-based film materials, the use of HNT improved the thermal stability of film material while CEO had an opposite effect. It was determined that instead of CEO, the use of CEO-encapsulated HNT in the preparation of starch-based antibacterial composite films caused a slower release of CEO from bioplastic film. Starch-based films containing CEO showed antibacterial property against both Gram-negative ( E. coli ) and Gram-positive ( S. aureus ) bacteria. The experimental results revealed that low-cost and eco-friendly oak tree acorn starch- CEO- HNT bioplastic films are promising for the food packaging sector.
