•Laponite enhanced the mechanical and barrier properties.•Gelatin–laponite composite films possess antioxidant activities.•Gelatin–laponite composite films can act as a biodegradable film in industries.
The biodegradable and biocompatible gelatin–laponite composite films were developed in this study. The effect of the concentration of laponite on the physicochemical properties of the gelatin–laponite film was investigated. The results suggested that the gel strength, mechanical properties, water vapor permeability and water solubility of gelatin–laponite composite films are significantly improved with the increase of the concentration of laponite. In addition, the microstructures of gelatin–laponite films were also characterized by scanning electron microscope (SEM) micrographs. The results of fourier transform infrared spectroscopy (FTIR) indicated that laponite facilitated the conformational changes of proteins films. Furthermore, gelatin–laponite films exhibited substantial enhancement of the quality of meat during storage, which was improved with the concentration of laponite. Hence, gelatin–laponite composite films could be potentially utilized in the development of the novel packaging material in food industries.
