The work aims to extend the properties of edible fresh-keeping film. Edible fruit fresh-keeping film was prepared with the layer-by-layer self-assembly electrostatic deposition technology. Meanwhile, the microstructure, transparency, hydrophilic-hydrophobic property and self-healing ability of the edible film were characterized. The edible film was of dense microstructure and high transparency, with the transmittance above 90%; the film was of high hydrophobicity and the contact angle θ was about 102°; the edible film could self-heal morphologically and mechanically and the edible film and self-healed film could hold the weight of 200 g and could not hold the weight of 300 g. It is concluded that these properties of edible fresh-keeping film have improved the fresh-keeping effect of the edible film.
