However, existing PE flat bags are prone to breaking or tearing when holding heavy or sharp-surfaced items, causing damage and posing safety hazards. Utility Model Content
[0003] The purpose of this utility model is to provide a heavy-duty PE flat bag to solve the problem that existing PE flat bags are easily crushed or torn when heavy or sharp items are placed in them, causing damage to the items and posing safety hazards.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a heavy-duty PE flat bag, including a bottom bag surface. The front and rear sides of the bottom bag surface are respectively provided with a front bag surface and a rear bag surface. The left and right sides of the bottom bag surface are respectively provided with a left bag surface and a right bag surface. A reinforcing bottom plate is provided at the bottom of the bottom bag surface. The left and right sides of the front bag surface extend to the outside of the left and right bag surfaces. The left and right sides of the rear bag surface extend to the outside of the left and right bag surfaces. A handle opening is provided at the top of the front and rear bag surfaces. A handle loop is provided at the edge of the handle opening.
[0006] Furthermore, the bottom bag surface, the front bag surface, the rear bag surface, the left bag surface, and the right bag surface are all provided with woven mesh on their inner sides, and the multiple woven meshes are arranged together to form an inner mesh bag with a top opening.
[0007] Furthermore, the inner mesh bag has several partition surfaces inside, which divide the internal space of the inner mesh bag into several placement cavities.
[0008] Furthermore, the front pocket surface includes a first main pocket surface, a first transition surface, and a first handle surface connected in sequence. The first main pocket surface is located on the front side of the bottom pocket surface. The left and right sides of the first main pocket surface are provided with first extension surfaces, and the first handle surface is provided with the handle opening.
[0009] Furthermore, a first reinforcing strip is provided at the folded edges of the first main bag surface and the first transition surface, as well as at the folded edges of the first transition surface and the first handle surface.
[0010] Furthermore, the rear bag surface includes a second main bag surface, a second transition surface, and a second handle surface connected in sequence. The second main bag surface is located on the rear side of the bottom bag surface.

Detailed Implementation
[0021] like Figure 1-4 As shown, a load-bearing PE flat bag includes a bottom bag surface 5. A front bag surface 1 and a rear bag surface 2 are respectively connected to the front and rear sides of the bottom bag surface 5. A left bag surface 3 and a right bag surface 4 are respectively connected to the left and right sides of the bottom bag surface 5. A reinforcing bottom plate 6 is connected to the bottom of the bottom bag surface 5. The left and right sides of the front bag surface 1 extend to the outside of the left bag surface 3 and the right bag surface 4. The left and right sides of the rear bag surface 2 extend to the outside of the left bag surface 3 and the right bag surface 4. The front side pocket 1 and the rear side pocket 2 are provided with handle openings at the top, and a handle loop 8 is installed at the edge of the handle opening. Users can more comfortably lift the flat bag through the handle loop 8. The handle loop 8 can also distribute the tension on the handle opening evenly on the edge of the handle opening, avoiding the tension from being concentrated on a small part of the handle opening and causing deformation of the handle opening. By reasonably designing the overall structure of the bag, it is ensured that it remains balanced and stable when loaded with heavy objects, reducing the risk of damage caused by uneven force.
[0022] The bottom bag surface 5, the front bag surface 1, the rear bag surface 2, the left bag surface 3, and the right bag surface 4 are all connected to woven mesh on their inner sides. The multiple woven meshes 7 are arranged together to form an inner mesh bag 7 with a top opening.
[0023] like Figure 3 As shown, the inner mesh bag 7 has several partition surfaces 9 connected inside. These partition surfaces 9 divide the internal space of the inner mesh bag 7 into several placement cavities, making it convenient to place different items separately and easy to use. Specifically, some of the partition surfaces 9 are arranged along the front-back direction to tighten the front and back sides of the inner mesh bag 7, and some are arranged along the left-right direction to tighten the left and right sides of the inner mesh bag 7. The connection between the partition surfaces 9 and the inner mesh bag 7 further enhances the structural strength of the inner mesh bag 7 and improves the load-bearing capacity of the flat bag.
[0024] The front pocket surface 1 includes a first main pocket surface 1-1, a first transition surface 1-3, and a first handle surface 1-4 connected in sequence. The first main pocket surface 1-1, the first transition surface 1-3, and the first handle surface 1-4 are integrally formed. The first main pocket surface 1-1 is connected to the front side of the bottom pocket surface 5. The left and right sides of the first main pocket surface 1-1 are connected to first extension surfaces 1-2. The first handle surface 1-4 has a handle opening. The folded edges of the first main pocket surface 1-1 and the first transition surface 1-3, and the folded edges of the first transition surface 1-3 and the first handle surface 1-4 are all connected to a first reinforcing strip 1-5. The first reinforcing strip 1-5 is X-shaped. The X-shaped structure can generate diagonal tensile force, increase the structural strength of the folded edge, and avoid damage to the folded edge during use.
[0025] The rear bag surface 2 includes a second main bag surface 2-1, a second transition surface 2-3, and a second handle surface 2-4 connected in sequence. The second main bag surface 2-1, the second transition surface 2-3, and the second handle surface 2-4 are integrally formed. The second main bag surface 2-1 is connected to the rear side of the bottom bag surface 5. The left and right sides of the second main bag surface 2-1 are connected to second extension surfaces 2-2. The second handle surface 2-4 has a handle opening. The folded edges of the second main bag surface 2-1 and the second transition surface 2-3, and the folded edges of the second transition surface 2-3 and the second handle surface 2-4 are all connected to second reinforcing strips. The second reinforcing strips are also X-shaped to increase the structural strength of the folded edges and prevent damage to the folded edges during use.
[0026] like Figure 4 As shown, the reinforcing bottom plate 6 is configured as a grid to increase the structural strength of the bottom bag surface 5 and prevent wear on the bottom bag surface 5.
[0027] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
