[0025] This utility model provides, for example Figure 1-5 The reusable PE packaging bag shown includes a packaging bag body 1, an outer bag body 2, an inner bag body 3, and a tear-resistant layer 4. The packaging bag body 1 is double-layered. A label strip 201 is provided on the lower surface of the outer bag body 2. The label strip 201 is adhesively applied to the outer surface of the outer bag body 2. A nitrogen inlet 202 is installed on one corner of the surface of the outer bag body 2. The nitrogen entering through the nitrogen inlet 202 fills the space between the outer bag body 2 and the inner bag body 3. Protective corner pieces 203 are provided on both lower sides of the outer bag body 2. The protective corner pieces 203 are rounded. The packaging bag body 1 is composed of an outer bag body 2 and an inner bag body 3. The outer bag body 2 is the outer surface of the packaging bag body 1, and the inner bag body 3 is the inner layer of the packaging bag body 1. A tear-resistant layer 4 is provided on the inner side of the outer bag body 2. The tear-resistant layer 4 is a reinforcing rib.

[0027] The working principle of this practical application is as follows:

[0028] Refer to the instruction manual appendix Figure 1-5For this type of reusable PE packaging bag, the bag adopts a double-layer design, consisting of an outer bag body 2 and an inner bag body 3. The outer bag body 2 serves as the outer surface of the packaging bag, while the inner bag body 3 serves as the inner layer. This design enhances the durability and protection of the packaging bag. A tear-resistant layer 4 is provided on the inner side of the outer bag body 2. This tear-resistant layer 4 uses cross-shaped reinforcing ribs to effectively improve the tear resistance of the packaging bag, making it less prone to damage during repeated use. Protective corner protectors 203 are provided on both lower sides of the outer bag body 2, and they are rounded. This design reduces the risk of the packaging bag being easily torn due to sharp edges during handling or stacking. A nitrogen inlet 202 is installed on one corner of the outer bag body 2. By filling it with nitrogen, the outer bag body 2 and the inner bag body 3 can be filled with nitrogen. Nitrogen is an inert gas that does not readily react chemically with other substances, thus effectively protecting the contents of the packaging bag from external factors such as oxidation and moisture. A pressing groove 501 is provided on one side of the surface and bottom of the bag edge 5, and a pressing strip 502 is provided at the edge. The two ends of the pressing strip 502 are matched with the pressing groove 501. A pressing groove 503 matching the size of the end of the bag edge 5 is provided on the inner side. This design makes the packaging bag more secure when sealed, preventing air leakage or water seepage. A sealing strip 601 is provided directly below the pinch strip 6 on one side of the upper end of the outer bag body 2, and a sealing groove 602 is provided directly above the pinch strip 6 on the other side. By pressing the sealing strip 601 to match the sealing groove 602, a tight seal can be achieved, further ensuring the airtightness of the packaging bag.

[0029] When using this packaging bag, place the items to be packaged into the inner bag 3, ensuring that the items are completely wrapped and placed in a suitable position. Inflate the packaging bag with an appropriate amount of nitrogen through the nitrogen inlet 202 to fill the space between the outer bag 2 and the inner bag 3. The amount of nitrogen should be adjusted according to the size and nature of the items to ensure that the items are adequately protected. If nitrogen inflation is not required, the bag can be used directly without nitrogen inflation. Press the sealing strip 601 and sealing groove 602 on the top of the outer bag 2 to ensure a tight fit and a secure and airtight seal. When it is necessary to open the packaging bag body 1, pinch the top and gently pull open the bag to remove the items.
