[0006] A first metal button is arranged on the side of the active layer away from the interlayer.
[0007] A second metal button is arranged on the upper half of the other side of the inner wall of the packing bag body.
[0008] The first metal button cooperates with the second metal button.
[0009] In a preferred example, the length of the active layer is 1.2-1.3 times the width of the interior of the packing bag body.
[0010] In a preferred example, a storage layer is fixedly arranged on one side of the inner wall of the packing bag body.
[0011] The vertical cross section of the storage layer is J-shaped, the storage layer and the active layer are located on the same side of the inner wall of the packing bag body, and the storage layer is located below the active layer.
[0012] A third metal button is arranged on one side of the inner wall of the storage layer.
[0013] The third metal button cooperates with the first metal button.
[0014] In a preferred example, a plurality of elastic belts are arranged on one side of the inner wall of the packing bag body.
[0015] The two ends of the elastic belt are connected to one side of the inner wall of the packaging bag body.
[0016] In a preferred example, the elastic belt is further configured as: part of the elastic belt is vertically arranged on one side of the inner wall of the packaging bag body.
[0017] Another part of the elastic belt is horizontally arranged on one side of the inner wall of the packaging bag body.
[0018] In summary, the utility model has the following beneficial technical effects:
[0019] 1. By arranging the interlayer on the movable layer, the position of the movable layer is adjusted according to the loading condition of the articles in the packaging bag body, so that the movable layer is always above the articles, and the interlayer is also always above the articles, thereby avoiding damage of the articles in the interlayer caused by the articles in the packaging bag.
[0020] 2. By arranging the storage layer, the third metal button is arranged in the storage layer, and the third metal button cooperates with the first metal button, so that the position of the movable layer is fixed when the packaging bag is not used.
[0021] 3. By arranging the second metal button and the first metal button, the first metal button cooperates with the second metal button, thereby limiting the position of the interlayer, avoiding disorder of the position of the movable layer during carrying of the packaging bag, and causing the articles in the interlayer to touch other articles.
