Paper-plastic packaging film and production process thereof

The invention discloses a paper-plastic packaging film and a production process thereof, and relates to the technical field of paper-plastic packaging films. According to the preparation method, artificially synthesized zeolite is adopted as an antibacterial agent main body, zinc ions are implanted into the surface and the interior of the zeolite through a co-deposition method, nano zeolite-zinc oxide with an antibacterial effect is prepared, and the nano zeolite-zinc oxide is modified by tridecafluorooctyltriethoxysilane, so that the antibacterial property of the nano zeolite-zinc oxide is improved, and the antibacterial property of the nano zeolite-zinc oxide is improved. The nano zeolite-zinc oxide is modified by a silane coupling agent, the dispersity and the stability of the nano zeolite-zinc oxide are improved, chitosan is adopted for further treating the nano zeolite-zinc oxide modified by the silane coupling agent, so that the nano zeolite-zinc oxide has hydrophilic/oleophobic characteristics, and a l
