[0023] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application, as follows.

[0024] like Figure 1 As shown, this embodiment provides a standing anti-fall packaging bag, including a packaging bag body 1; a screw-on discharge port 3 is provided at one corner of the storage surface belt; the packaging bag body 1 is composed of three PE plastic sheets 2, including a front side, a rear side, and a bottom side; the upper, left, and right sides of the front side are heat-pressed to the upper, left, and right sides of the rear side, respectively; the lower side of the front side is heat-pressed to one side of the bottom side; and the lower side of the rear side is heat-pressed to the other side of the bottom side. Because the bottom side is provided, the bottom of the packaging bag is stretched open during use or storage, allowing the packaging bag to stand upright, making it easy to use, take, store, and store.

[0025] Furthermore, the front side of the packaging bag body 1 is an isosceles trapezoid, and the length of the upper side is smaller than the length of the bottom side; the structure and shape of the rear side are consistent with the front side, and is an isosceles trapezoid, and the length of the upper side is smaller than the length of the bottom side.

[0026] Furthermore, the sum of the bottom side lengths of the front and rear sides of the packaging bag body 1 is greater than or equal to the perimeter of the bottom surface, so that when the bottom surface is stretched out, the top cross-sectional area is not large and the bottom cross-sectional area is not small, which would cause the packaging bag to be unstable.

[0027] Furthermore, the bottom of the bottom surface of the packaging bag body 1 is also provided with reinforcing ribs; the reinforcing ribs can further enhance the unfolding strength of the bottom surface, thereby enabling the packaging bag to stand better.

[0028] Furthermore, the packaging bag body 1 is provided with reinforcing ribs on the lower side, left side, and right side of the front side, and reinforcing ribs on the lower side, left side, and right side of the rear side. The reinforcing ribs can further enhance the upright strength of the front side and rear side, thereby enabling the packaging bag to stand better.

[0029] Further, such as Figure 2 As shown, a shapeable opening strip 4 can be added to the connection between the lower edge of the front side and one side of the bottom surface of the packaging bag body 1; a shapeable opening strip 4 is also added to the connection between the lower edge of the rear side and the other side of the bottom surface, so that the packaging bag can stand better.

[0030] Furthermore, a shapeable expansion strip 4 can be provided in the middle portion between the front side and the rear side of the packaging bag body 1 so that the middle and upper portion of the packaging bag is also supported when the packaging bag stands.

[0031] Further, such as Figure 3 、 Figure 4 as well as Figure 5 As shown, the bottom surface of the packaging bag body 1 is circular, or elliptical, or rhombus, or spindle-shaped, or hexagonal, or octagonal; the closer the longitudinal length and the transverse length of the bottom surface are to being equal, the more stable the packaging bag stands. The utility model designs the bottom surface to be elliptical, or rhombus, or hexagonal, or octagonal, or octagonal, or decagonal, or dodecagonal, or a polygon with an even number of sides of more than twelve sides, which can make the longitudinal length and the transverse length of the bottom surface closer to being equal, thereby making the packaging bag stand more stable.

[0032] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
