[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, this utility model provides a film bag that is easy to stack quickly, including a film bag body 1, a reinforcing layer 2 on the outer surface of the film bag body 1, the reinforcing layer 2 being tightly connected to the film bag body 1 by a hot melt bonding process, two protruding strips 3 being fixedly connected to one end of the reinforcing layer 2, and an iron strip 31 being fixedly connected to one end of the two protruding strips 3, and a groove 5 for cooperating with the two protruding strips 3 being opened at the other end of the reinforcing layer 2, and a magnetic coating 51 for cooperating with the iron strip 31 being opened on the inner surface of the two grooves 5, the protruding strips 3 cooperating with the magnetic coating 51 in the grooves 5 at the other end, and the magnetic attraction of the iron strip 31, so that adjacent film bags can be tightly connected when stacked, which greatly improves the stability and convenience of stacking film bags and reduces the risk of film bags slipping or collapsing during the stacking process.

[0027] Specifically, both protrusions 3 are made of elastic rubber material. The two protrusions 3 are symmetrically distributed along the transverse center line of the reinforcing layer 2. The elastic rubber material can play a buffering role to prevent the protrusions 3 from being damaged due to collision when they are in contact with the groove 5. At the same time, the symmetrical distribution ensures that the film bags are evenly stressed when stacked, which further enhances the stability of the stack.

[0028] like Figures 1 to 5As shown, two handles 4 are fixedly connected to the top of the membrane bag body 1, which makes it convenient for users to carry and move the membrane bag. Especially when the membrane bag is full of items, the handles 4 make the carrying process easier and less strenuous, improving the convenience of using the membrane bag.

[0029] Furthermore, the outer surfaces of both iron bars 31 are coated with an anti-rust coating, which effectively prevents the iron bars 31 from rusting and extends their service life.

[0030] like Figures 1 to 5 As shown, the reinforcing layer 2 includes a strengthening layer 21, which is connected to the membrane bag body 1. A shock-absorbing layer 22 is provided on one side of the strengthening layer 21, and a stabilizing layer 23 is provided on one side of the shock-absorbing layer 22. This multi-layered structure design gives the membrane bag better overall performance. The strengthening layer 21 enhances the overall strength of the membrane bag, the shock-absorbing layer 22 provides cushioning protection, and the stabilizing layer 23 ensures the stability of the membrane bag's shape, thus improving the membrane bag's adaptability to different usage environments and external forces.

[0031] It is worth noting that the reinforcing layer 21 is woven from high-strength fibers and is tightly bonded to the membrane bag body 1 using a special bonding process. The shock-absorbing layer 22 is made of elastic rubber, and the stabilizing layer 23 is made of lightweight aluminum alloy and is processed into a mesh shape using a special process. The reinforcing layer 21, woven from high-strength fibers and tightly bonded to the membrane bag body 1, provides strong tensile and puncture resistance. The elastic rubber of the shock-absorbing layer 22 can effectively absorb impact force. The lightweight aluminum alloy mesh structure of the stabilizing layer 23 reduces the weight of the membrane bag while ensuring strength. The three work together to enhance the durability of the membrane bag.

[0032] Working principle and process: During use, when stacking membrane bags is required, the protrusion 3 at one end of the reinforcing layer 2 of one membrane bag is aligned with the groove 5 at the other end of the reinforcing layer 2 of another membrane bag and inserted. Due to the mutual attraction between the iron strip 31 at one end of the protrusion 3 and the magnetic coating 51 on the inner surface of the groove 5, the adjacent membrane bags are tightly connected together, achieving fast and stable stacking. The high-strength fibers of the reinforcing layer 21 can resist external tensile and puncture forces, protecting the membrane bag body 1. When the membrane bag is subjected to external impact, the elastic rubber of the shock-absorbing layer 22 will deform, absorbing and dispersing the impact force, reducing the impact on the items inside the membrane bag. The lightweight aluminum alloy mesh structure of the stabilizing layer 23 maintains the overall shape of the membrane bag and prevents the membrane bag from deforming due to uneven force.
