The utility model relates to the technical field of
preservative film bags, in particular to a vegetable and fruit
preservative film bag with a ventilation structure, which comprises a bag surface, a folding surface is fixedly arranged on the side surface of the bag surface, a screw rod is arranged on the outer surface of the folding surface in a penetrating manner, a sliding block sleeve column is mounted on the outer surface of the screw rod in a threaded manner, and the sliding block sleeve column is provided with a ventilation structure. And an outer ring is fixedly mounted on the outer surface of the sliding block sleeve column. According to the vegetable and fruit
preservative film bag with the ventilation structure, after
fruits and vegetables are put into the preservative film bag and the sealing opening is sealed, the sliding
barrel groove can be pulled to move through the outer cover, so that the sliding
barrel groove can drive the contact blocking surface to slide on the outer surface of the sliding block sleeve column; the contact blocking face can be separated from the rubber blocking piece, so that the gas circulation channel is opened, air inside and outside the preservative film bag is freely exchanged, the concentration of
oxygen and
carbon dioxide in the bag is effectively adjusted, an accurately-matched microenvironment is created for
fruits and vegetables, and it is ensured that the
fruits and vegetables are always kept in a fresh state in the storage process.
