[0002] The sealing film device can tightly package the opening of the prefabricated vegetable packaging container with a preservative film or other sealing film, forming a relatively independent sealed space, effectively preventing external air, moisture, dust and microorganisms from entering the packaging interior, reducing the contact between the prefabricated vegetable and the external environment, thereby prolonging its shelf life. By sealing the film, the moisture in the prefabricated vegetable can be prevented from being lost, and the dish can be prevented from becoming dry and having a poor taste. At the same time, the contact between oxygen and the dish can be reduced, the oxidation reaction can be slowed down, the dish can be prevented from discoloration and taste change, and the original color, flavor and nutrients can be maintained. The prefabricated vegetable sealed by the sealing film is more convenient to store and transport and is less likely to be contaminated and damaged.
