[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides an embodiment: a sterilization composite film packaging bag, comprising: a sterilization bag 1, an outer bag 3 is provided in the excavation of the sterilization bag 1, the outer bag 3 is connected to the sterilization bag 1 through a rubber layer 4, the sterilization bag 1, the outer bag 3 and the top of the rubber layer 4 are connected with a connecting belt 5, the inner wall of the connecting belt 5 is provided with a sealing strip 6, and an exhaust mechanism 7 for discharging the air in the sterilization bag 1 is provided above one side of the sterilization bag 1, the outer bag 3 and the rubber layer 4. The rubber layer 4 is made of rubber material, and the rubber has good flexibility. It can be used for buffering after a certain thickness. When the packaging bag falls, the rubber contacts the ground first, so that the protective performance of the articles is better, and the packaged articles are prevented from being damaged due to large force.

[0022] See also Figure 1 In this embodiment, the inner wall of the sterilization bag 1 is provided with a wear-resistant layer 2, which is made of polycarbonate. Articles often come into contact with the inner wall of the sterilization bag 1, and the wear-resistant layer 2 improves the wear resistance and prolongs the service life.

[0023] See also Figure 1-2 In this embodiment: the sealing strip 6 includes a convex strip 601, which is fixed to the inner wall of one end of the connecting strip 5, and the inner wall of the other end of the connecting strip 5 is provided with a groove 602 which is connected to the convex strip 601 by pressing. By pressing the convex strip 601 into the groove 602, the sealing of the connecting strip 5 can be achieved, thereby sealing the sterilization bag. When it needs to be opened, the connecting strips 5 at both ends are pulled to separate the concave strip 601 and the groove 602. After separation, the items in the sterilization bag 1 can be taken out.

[0024] See also Figure 3In this embodiment: the exhaust mechanism 7 includes an air hole 701, and the air hole 701 is arranged at the same position above one side of the sterilization bag 1, the wear-resistant layer 2, the outer bag 3 and the rubber layer 4. The side of the air hole 701 away from the wear-resistant layer 2 is connected with an external threaded tube 702, and the external threaded tube 702 is fixed on the outer bag 3. The outer wall of the external threaded tube 702 is provided with a sleeve 703, and a cylinder 704 is installed on the inner wall of one side of the sleeve 703. The inner wall of the sleeve 703 is provided with a thread 705, and the sleeve 703 is rotatably installed with the external threaded tube 702 through the thread 705. After the items are loaded and the sealing strip 6 is sealed, the sleeve 703 is rotated to separate it from the external threaded tube 702. After separation, the cylinder 704 also leaves the external threaded tube 702, and then the outer bag 3 is squeezed to discharge the gas in the sterilization bag 1. After discharge, the sleeve 703 is screwed on again, and the cylinder 704 seals the air hole 701, which is easy to operate and can ensure the reliability of bag compression.

[0025] See also Figure 3 In this embodiment: a sealing ring 706 is provided on the outer wall of the cylinder 704, and the sealing ring 706 improves the sealing performance of the cylinder 704 to the threaded tube 702.

[0026] See also Figure 1 In this embodiment: handles 8 are installed on the outer walls at both ends of the connecting belt 5, and Velcro 9 is provided on the side where the two handles 8 are close to each other. The handles 8 are convenient for carrying the packaging bag, and the Velcro 9 can stick the two handles 8 together, which is convenient for workers to carry.

[0027] Working principle: the rubber layer 4 is elastic. After the packaging bag falls to the ground, the rubber layer 4 contacts the ground first, which can have a certain buffering effect on the items in the bag and improve the protection effect of the items. After the items are loaded, the convex strip 601 is pressed into the groove 602 and sealed, and the sleeve 703 is rotated to make the sleeve 703 leave the external threaded tube 702, so that the cylinder 704 leaves the air hole 701 and the external threaded tube 702, and the outer bag 3 is squeezed. The gas in the sterilization bag 1 can be discharged through the air hole 701, and finally the sealing ring 706 is inserted into the external threaded tube 702 and the air hole 701, and the sleeve 703 is rotated to fix the sleeve 703 on the external threaded tube 702 to seal the air hole 701, so that the gas in the sterilization bag 1 can be easily discharged and the sterilization bag 1 is compressed. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
