[0026] Working principle: Before using the utility model, the operator first unzips the zipper 5, opens the drying cover 6, and places the desiccant inside the breathable bag 3 and the extension bag 4, and pulls up the zipper 5. At this time, the drying cover 6 and the extension bag 4 are sewn together. At this time, the operator places the product that needs to be dried and stored directly inside the packaging bag bottom 1 and the packaging bag cloth layer 2. After filling, the operator tightens the sealing rope 8 and fastens the buckle. At this time, the packaging bag sealing layer 9 can ensure that the packaging bag cloth layer 2 is airtight, so the inside of the packaging bag cloth layer 2 is in a relatively sealed state, and the supporting feet 10 and rubber pads 11 can prevent the packaging bag bottom 1 from directly contacting the ground, preventing the wet ground from wetting the utility model. When the product is placed inside the packaging bag cloth layer 2, the desiccant will absorb the moisture inside the packaging bag cloth layer 2 through the breathable bag 3, thereby ensuring that the inside of the packaging bag cloth layer 2 is in a relatively dry state, so that the product can be stored and transported in a relatively dry environment.
