The invention discloses a preparation process of a food fresh-keeping film with an antibiotic coating, and relates to the technical field of fresh-keeping film preparation, and the preparation process comprises the following steps: step 1, raw material preparation: preparing 50-60 parts of a PVC resin material, 15-17 parts of a thickening agent and 6-7 parts of epoxidized soybean oil; the winding machine is used for winding the transparent preservative film, the pressure is consistent and uniform during winding, in this way, the film roll cannot be wrinkled, it is guaranteed that the film roll is flat, attractive and the like, the winding machine solves the problem of no tailings, consumption is reduced, the labor intensity of workers is reduced, the wound transparent preservative film roll is compressed through the air compressor, and the production efficiency is improved. Air remaining in the film roll is exhausted, the film roll is tighter and more compact, transparency and attractiveness of the preservati
