[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a side anti-tensile LDPE tubular bag as shown in Figures 1 - 3 which includes a bag body 1. An opening 2 is provided at the top end of the bag body 1, and the opening 2 is used for placing items into the interior of the bag body 1;

[0029] Furthermore, a tensile resistance mechanism 3 is arranged outside the bag body 1. The tensile resistance mechanism 3 includes: a first tensile belt 31, a second tensile belt 32 and a strengthening component 33. The first tensile belt 31 is fixedly connected to the outer wall of the bag body 1. The first tensile belt 31 is annular and surrounds the opening 2 position of the bag body 1. Moreover, anti-slip textures are provided on the outer wall of the first tensile belt 31 for distinguishing the first tensile belt 31 from the second tensile belt 32; the second tensile belt 32 is fixedly connected to the outer wall of the bag body 1. The first tensile belt 31 and the second tensile belt 32 are symmetrically arranged with the middle part of the bag body 1 as the center. The second tensile belt 32 is also annular and surrounds the bottom end of the bag body 1 for enhancing the load-bearing capacity of the bottom of the bag body 1; the strengthening component 33 is arranged between the first tensile belt 31 and the second tensile belt 32 for enhancing the tensile resistance of the bag body 1 at positions other than the opening 2 and the bottom end, thereby avoiding the situation that the bag body is broken due to too many items stored inside the LDPE tubular bag, which is convenient for use.

[0030] Specifically, the strengthening component 33 includes: a third tensile belt 331, a fourth tensile belt 332 and a tensile resistance component 333. One ends of a plurality of third tensile belts 331 are all fixedly connected to the first tensile belt 31, and the other ends of the plurality of third tensile belts 331 are all fixedly connected to the second tensile belt 32; the plurality of third tensile belts 331 are equidistantly arranged between the first tensile belt 31 and the second tensile belt 32, and the plurality of third tensile belts 331 are all fixedly connected to the bag body 1. The third tensile belt 331 connects the first tensile belt 31 and the second tensile belt 32 together, thereby further enhancing the load-bearing capacity of the entire bag body 1; the plurality of fourth tensile belts 332 are equidistantly arranged between adjacent two third tensile belts 331, and the plurality of fourth tensile belts 332 are all fixedly connected to the bag body 1. The plurality of fourth tensile belts 332 connect the plurality of third tensile belts 331 together, thereby improving the tensile resistance of the side of the entire bag body 1; a plurality of tensile resistance components 333 are arranged between the plurality of third tensile belts 331 and the plurality of fourth tensile belts 332.

[0031] Furthermore, the tensile component 333 includes: a first reinforcing band 3331, a second reinforcing band 3332, and a third reinforcing band 3333. A plurality of first reinforcing bands 3331 are fixedly connected at equal intervals between a plurality of fourth tensile bands 332. A plurality of first reinforcing bands 3331 are respectively fixedly connected between two adjacent third tensile bands 331. A plurality of first reinforcing bands 3331 are all fixedly connected to the bag body 1. The second reinforcing band 3332 is fixedly connected to the inner wall of the first reinforcing band 3331. The second reinforcing band 3332 is fixedly connected to the bag body 1. The cross-sections of the first reinforcing band 3331 and the second reinforcing band 3332 are both in an X shape. The X-shaped first reinforcing band 3331 and the second reinforcing band 3332 further improve the tensile capacity of the side of the entire bag body 1. The X-shaped design enables the force to be evenly distributed along the two diagonals of the X shape when the structure is subjected to a tensile force. In this way, each part can bear a part of the tensile force instead of all the forces concentrating on one point. Moreover, the X-shaped cross-layout provides additional support points for the structure. These support points can support each other when the structure is stretched, thereby increasing the overall stability of the structure and preventing the structure from deforming. When the X-shaped structure is stretched, its cross part can effectively resist the shear force. This design helps to prevent the structure from suffering shear failure under the action of an oblique force. Since the X-shaped structure has cross supports in two directions, this increases the overall stiffness of the structure, making it not easy to bend or twist when subjected to a tensile force. The upper and lower layers in the double-layer structure are locked to each other through the X-shaped connection points. This interlocking effect enables the two-layer structure to mutually restrict and jointly bear the tensile force when stretched. The X-shaped structure helps to optimize the stress distribution in the material, reduce stress concentration, thereby improving the fatigue life and fracture resistance of the material. The X-shaped cross part forms an additional reinforcing layer in the structure, which is equivalent to increasing the effective load-bearing area of the material, thereby improving the tensile capacity. Under dynamic loading conditions, the X-shaped structure can better absorb and disperse energy, reducing fatigue damage caused by vibration. A plurality of third reinforcing bands 3333 are fixedly arranged between the first reinforcing band 3331 and the second reinforcing band 3332. The cross-section of the third reinforcing band 3333 is in a wavy shape. The wavy third reinforcing band 3333 can evenly distribute the tensile force applied to the bag to the entire band, reducing local stress concentration, thereby reducing the risk of damage to the bag material due to local overloading.
