[0035] The sealing strip 4005 and the sealing groove 4004 are engaged with each other. There are two groups of sealing grooves 4004 and sealing strips 4005. After people store items in the bag body 1, they can press the two groups of sealing strips 4005 to engage the sealing strips 4005 in the sealing grooves 4004, thereby achieving double sealing for the items stored in the bag body 1 and preventing water vapor from invading the bag body 1 and causing the items to become moldy and damaged.

[0036] Preferably, the outer walls of both sides of the bag body 1 are respectively bonded with a bristle pad 4006 and a connecting strip 4002, a fluff pad 4003 is bonded to the outer wall of one side of the connecting strip 4002, the fluff pad 4003 and the bristle pad 4006 are bonded to each other, and a pull ring 4001 is bonded to the outer wall of one side of the connecting strip 4002, and the cross section of the pull ring 4001 is arc-shaped, so that people can pull the connecting strip 4002 to separate the fluff pad 4003 and the bristle pad 4006 when they need to open the packaging bag, and the bristle pad 4006, the connecting strip 4002, and the fluff pad 4003 are bonded to each other. There are two groups of pads 4003 and pull rings 4001, and the two groups of bristle pads 4006, connecting strips 4002, fluff pads 4003 and pull rings 4001 are respectively arranged at the two ends of the top of the bag body 1. After the two groups of sealing strips 4005 are clamped and fixed with the sealing grooves 4004, people can adhere the fluff pads 4003 and the bristle pads 4006 on one side of the connecting strips 4002 to each other, thereby locking and fixing the two ends of the bag body 1, and avoiding the situation where the sealing strips 4005 break from both ends when people take and carry the bag body 1.

[0037] Preferably, the exhaust assembly 3 includes a valve body 3001 fixedly connected to one side of the bag body 1, one end of the valve body 3001 is fixedly connected to a limiting cover 3005, the limiting cover 3005 is fixedly connected to an outer wall of one side of the bag body 1, an inner wall of one side of the valve body 3001 and an outer wall of one side of the limiting cover 3005 are respectively provided with a first exhaust hole 3002 and a second exhaust hole 3006, the circumferential inner wall of the valve body 3001 is fixedly connected to a ring plate 3007, the circumferential outer wall of the ring plate 3007 is fixedly connected to elastic members 3004 distributed in a circular shape at equal distances, and one side of the elastic member 3004 away from the ring plate 3007 is provided with a first exhaust hole 3002 and a second exhaust hole 3006. A sealing gasket 3003 is fixedly connected to the end, and one end of the sealing gasket 3003 is in close contact with the inner wall of one side of the valve body 3001. The sealing gasket 3003 can be made to be in close contact with the inner wall of the valve body 3001 through the elastic member 3004, thereby ensuring the overall sealing of the valve body 3001 when the exhaust operation is not performed. The air inside the bag body 1 can be discharged as much as possible through the exhaust component 3, and the one-way ventilation of the exhaust component 3 can be achieved through the sealing gasket 3003 inside the valve body 3001, thereby extending the storage time of the items in the bag body 1 and preventing the items from getting moldy when stored in the bag for a short period of time.

[0038] Working principle: After people store items in the bag body 1, they can press the two sets of sealing strips 4005 to snap the sealing strips 4005 into the sealing groove 4004, thereby achieving double sealing when storing items in the bag body 1, preventing water vapor from invading the bag body 1 and causing the items to become moldy and damaged. After the two sets of sealing strips 4005 are snapped and fixed to the sealing groove 4004, people can stick the fluff pad 4003 on one side of the connecting strip 4002 to the bristle pad 4006 to each other, thereby locking and fixing the two ends of the bag body 1, preventing people from When taking and placing the carrying bag body 1, the sealing strip 4005 may break from both ends. At the same time, the anti-mildew coating 1003 can have a wide range of efficient and long-term sterilization and inhibition capabilities against molds and yeasts, further improving the overall anti-mildew performance of the packaging bag. The air inside the bag body 1 can be discharged as much as possible through the exhaust component 3. At the same time, the sealing gasket 3003 inside the valve body 3001 can achieve one-way ventilation of the exhaust component 3, thereby extending the storage time of the items in the bag body 1 and preventing the items from getting moldy when stored in the bag for a short period of time.
