AB  - Plastic waste is one of the major threats to the environment, and an urgent need 
      to replace synthetic plastics with sustainable materials is progressively 
      growing. Herein, sustainable films based on chitosan, Satureja, and Thyme 
      essential oils (EOs), and chitosan nanofibers (NF) were developed for the first 
      time. To this end, 1% (w/w) of EOs and 2 wt% of NF were incorporated into the 
      chitosan solution. Despite the very similar chemical structure of carvacrol and 
      thymol, which are the major constituents of Satureja and Thyme EOs, respectively, 
      they imposed notably different effects on the physicochemical properties of 
      chitosan films. Thyme EO was more efficient at establishing hydrogen bonds with 
      chitosan. The disruptive effect of EOs on the crystalline network of chitosan was 
      demonstrated through X-ray diffraction analysis. Satureja and Thyme EOs decreased 
      and increased the barrier property of the chitosan films against water vapor, 
      respectively. However, the barrier property was greatly improved in the presence 
      of chitosan nanofibers. Satureja EO exhibited a more efficient antibacterial 
      property against E. coli rather than Thyme EO. The fruits and vegetables, coated 
      by the chitosan/EO/NF system, were less perished as compared with the control and 
      chitosan-coated samples indicating the promising potential of the developed 
      system to be used as edible and sustainable films and coatings due to their 
      enhanced antibacterial and barrier properties.
