[0022] In order to make the technical problem, technical scheme and beneficial effect of the utility model clearer, the utility model is further described in detail in connection with the drawings and examples.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] As Figures 1-4As shown, the M-fold bag includes a bag body 1, the upper end of which is connected to a hanging strap 2 on both sides, and a feeding port 3 in the middle of the upper end;

[0024] The lower end of the bag body 1 is a bag bottom 6; the bag body 1, the hanging strap 2, and the feeding port 3 are integrally formed, reducing the processing procedures in the later stage of sewing the hanging strap on the bag body, reducing the needle holes on the bag body, ensuring the sealing performance of the bag body, and effectively ensuring the connection strength of the hanging strap and the bag body.

[0025] Specifically, the bag body 1 and the feeding port 3 are square when unfolded, and are two M-shaped openings opposite each other when folded.

[0026] Specifically, the stress end of the hanging strap 2 is connected through a sewing area 4, ensuring the connection strength between the horizontal edges of the hanging strap 2, and the non-stress end of the hanging strap 2 is connected through a hot-press welding area 5, ensuring the sealing performance between the vertical edges of the hanging strap 2.

[0027] Specifically, the unfolded edge of the bag bottom 6 is integrally connected with the M-shaped folded edge through the sewing area 4, and the bag is formed into a double-V-shaped square bottom after being filled with materials, so that the bag is not easy to be poured.

[0028] Specifically, the side edge joint of the feeding port 3 is fixedly connected by the hot-press welding area 5, further ensuring the sealing performance of the feeding port.

[0029] In the production process, the bag body 1 is unfolded into a square structure, is formed by an M-fold forming machine, so that the two opposite side walls of the bag body 1 are bent inward into an M shape, and is subjected to layered hot-press welding by a layered hot-press welding machine along the axial direction of the bag body to form a hot-press welding area 5 on the two same-direction V-shaped folds of the M-shaped side wall, and further, the hot-press welding area 5 is symmetrically cut; at this time, the two edges of the two same-direction V-shaped folds are connected by the hot-press welding area 5 to form a hanging strap, and the two vertical edges of one opposite-direction V-shaped fold are connected by the hot-press welding area 5 to form a feeding port.

[0030] The connection of the hanging strap and the feeding port which does not bear tension is connected by the hot-press welding area, ensuring the sealing performance of the M-fold bag, the connection of the hanging strap and the sealing edge of the bag bottom is connected by the sewing area, ensuring the stability of the stress area connection, and the mixed connection of the hot-press welding area and the sewing area accelerates the processing speed of the bag, reduces the amount of manual use, and can ensure the uniform stability of the processed bag.
