Dropping-off-prevention packaging bag

The invention relates to the field of packaging, in particular to a dropping-off-prevention packaging bag. The dropping-off-prevention packaging bag comprises a packaging bag body, a packaging bag clamping head and a packaging bag opening; a first sticking strip is arranged on the upper portion of the packaging bag clamping head, and a second sticking strip is arranged on the upper portion of the packaging bag body; and a plastic packaging strip is arranged on the lower portion of the packaging bag body. According to the packaging bag, the second sticking strip is arranged on the upper portion of a common packaging bag body; after objects are contained in the bag body, the packaging bag clamping head is folded back to the packaging bag body; the first sticking strip is bonded with the packaging bag body, and the second sticking strip is also bonded with the packaging bag body, so that the clearance between the packaging bag opening and the packaging bag body is quite small. The objects cannot slide out from the bag opening, and the plastic packaging strip is arranged on the lower portion of the packaging bag body, so that when the packaging objects are strip-shaped, puncturing of the objects to the packaging bag is not prone to happening, and the objects are not prone to dropping off, so that losses are reduced.
