Preparation and Characterization of Antibacterial Zn-Coated High Density Polyethylene Films by Vacuum Evaporation Technology
Zn-coated HDPE films with different amount of zinc deposition were prepared via vacuum evaporation technology. AFM images showed that the size of Zn particles was decreasing evidently with the increase of the amount of Zn deposition on HDPE substrate. The Zn-coated HDPE films exhibited excellent antibacterial activity, especially for S. aureus. Compared with the HDPE film, the improvement of the barrier properties of the Zn-coated HDPE films was observed. Moreover, the barrier properties of the Zn-coated HDPE films were increasing with the elevation of the Zn content on HDPE films. The as-prepared Zn-coated HDPE films have a promising foreground applied in food packaging.
