     Related Art 
     Logistics transportation has become an indispensable field in modern society. For the transportation of goods, in addition to the requirements for fast, the protection of the transported goods is also quite demanding. For example, requirements for shockproof, cushioning, and waterproofing of packing materials. 
     With the development of science and technologies, electronic objects are moving toward a trend of thinness and lightness, and they are mainly based on large sizes. Therefore, shockproof, cushioning, and waterproofing are more important for packing materials. 
     The traditional shock-absorbing packing material provides limited shockproof and cushioning effects, and the protection and space for accommodating a conveying object does not completely match the volume of the conveying object. This makes the shockproof, and cushioning effect greatly reduced.

     DETAILED DESCRIPTION 
       FIG. 1  is an appearance schematic diagram of an M-type inflatable bag  1  according to an embodiment of the present invention. The M-type inflatable bag  1  includes a bottom wall  11 , two side walls  12 , and two protective walls  13 . 
     In some embodiments, the M-type inflatable bag  1  can be stacked by a plurality of diaphragms, formed by heat sealing means, inflatable formation, and has a heat sealing line  16   a  between the gas columns. 
     The bottom wall  11  includes a plurality of bottom gas columns  111 . Each of the side walls  12  includes a plurality of side gas columns  121 . Each side wall  12  is located on two opposite sides of the bottom wall  11 , and each side wall  12  includes a first side A and a second side B that are opposite to each other. The side gas columns  121  adjacent to the first side A of the side walls  12  include a limiting gas column  1211 . The volume of the limiting gas column  1211  is less than that of the other side gas columns  121 , and the opposite limiting gas columns  1211  are adhered to each other. With this structure in an extension direction of the side wall  12 , the distance between the two side walls  12  is smaller than the saturation of the limiting gas column  1211  compared with the other side gas column  121 , which can effectively shrink the two side walls  12 , not causing the two side walls  12  in the extension direction, the distance between the two expands outward. 
     In an embodiment, the opposite limiting gas columns  1211  are adhered by the heat sealing line  16   a , or in other manners such as glue. The side walls  12  and the bottom wall  11  are divided at a joint of the limiting gas columns  1211  to form a receiving space O and a limiting space R, The receiving space O can be socketed to the conveying object. The present invention is not limited thereto. Based on the above, the limiting gas column  1211  has a function of causing the side wall  12  to retract, so that the socket can be matched with the conveying object. However, in the limiting space R, the surrounding side wall  12  (and the protective wall  13 ) unfolds a corner area that can be held against the box. 
     The protective wall  13  includes a plurality of protective gas columns  131 , and the protective walls are respectively located outside the side walls. The protective wall  13  may be disposed on the outer side of each side wall  12  in an additional manner, or may be in a heat sealing manner to bond the upper side of the protective wall  12  with the upper side of the side wall  12 , and the outer side is folded, that is, can be located on the outside of the side wall  12  while protecting the internal side wall  12  and the socked conveying object. In an embodiment, the conveying object is an electronic panel, the M-type inflatable bag  1  is socked on the corner of the electronic panel. 
       FIG. 2  is an appearance schematic diagram of an M-type inflatable bag  1  according to an embodiment of the present invention. In this embodiment, limiting gas columns  1211  include two micro gas columns  1211 ′. In addition to the manner of making the volume of the limiting gas column  1211  less than that of the other side gas columns  121 , the two side walls  12  may also be prevented, in the manner of the two micro gas columns  1211 ′, from expanding outward in the extension direction. 
     In some embodiments, to make the structure of the M-type inflatable bag  1  more stable, the M-type inflatable bag  1  further includes an adhesion member, configured between the side wall  12  and a protective wall  13 , bonding the side wall  12  and the protective wall  13 , and making it stable. The adhesion member can be a heat sealing point of the heat sealing, a heat sealing line  16   a , or in a manner of applying an adhesive (adhesive layer) to bond the side wall  12  and the protective wall  13 . 
     Referring to  FIG. 1  again, in this embodiment, two connecting walls  15  are further included. The connecting wall  15  includes a plurality of connecting gas columns  151 . Each of the connecting walls  15  is located an upper side of the side wall  12  and the protective wall  13 , and two sides of the connecting wall  15  are connected to the side wall  12  and the protective wall  13 . In some embodiments, the M-type inflatable bag  1  is added independently, combined with side wall  12  and protective wall  13 . In other some embodiments, the side wall  12  and the protective wall  13  are originally stacked by a plurality of diaphragms, formed by means of heat sealing, after applying a heat sealing line  16   a  to the joint between the side wall  12  and the protective wall  13  and then folding outward. However, in this embodiment, the two heat sealing lines  16   a  are disposed by heat sealing to form a connecting gas column  151 , which can facilitate the folding of the protective wall  13 . That is, the present invention does not limit the manner in which the protective wall  13  is disposed outside the side wall  12 . 
     In some embodiments, the shape of the protective gas column  131  may correspond to the limiting gas column  1211  or the micro gas column  1211 ′. That is, during the production of the M-type inflatable bag, the structure of the protective gas column  131  can further be designed such as the same as the limiting gas column  1211  or the micro gas column  1211 ′, so that in the overlapping, folding structure, can be more tight, and reduce the overall volume of the M-type inflatable bag  1 . 
       FIG. 3  is an appearance schematic diagram of an M-type inflatable bag  1  according to an embodiment of the present invention. In this embodiment, the M-type inflatable bag  1  further includes a diaphragm  14  disposed on the receiving space O, two sides of the diaphragm  14  are bonded with the side wall  12 , and divides the receiving space O into a first space S 1  and a second space S 2 . Based on this structure, the shock absorption and cushioning effects of the M-type inflatable bag can be increased. However, in this embodiment, the diaphragm  14  includes a plurality of rib structures  141 , each of the rib structures  141  is generated by a heat sealing line  16   a  between the diaphragm  14  and each adjacent side gas column  121 , which is bonded by a heat sealing point. The rib structure  141  can increase the grip between the M-type inflatable bag  1  and the conveying object, however, the present invention does not limit the way in which the diaphragm  14  is added to the receiving space O. 
     In some embodiments, a bottom of each of the protective walls  13  is flush with a plane in which the bottom wall  13  is located. However, in other some embodiments, the bottom of each of the protective walls  13  protrudes from a plane in which the bottom wall  11  is located. That is, the present invention does not limit the height of the protective wall  13 , and uses different height of the protective wall  13  depending on the needs of an operator or a user and the consideration of the cushioning effect. 
     Referring to  FIG. 4  to  FIG. 6C ,  FIG. 4  is a partial schematic diagram of an M-type inflatable bag according to an embodiment of the present invention,  FIG. 6A  is a partial schematic diagram of an unsaturated state of an M-type inflatable bag according to an embodiment of the present invention,  FIG. 6B  is a partial schematic diagram of an embodiment 6B shown in  FIG. 2 , and  FIG. 6C  is a partial side view of an unsaturated state of an M-type inflatable bag according to an embodiment of the present invention. 
     One side of a connecting portion  20  is connected to the side wall  12 , and the other side is connected to the bottom wall  11 . In this embodiment, a joint between the bottom wall  11  and each side wall  12  includes a plurality of first heat sealing nodes  171  spaced apart and a plurality of second heat sealing nodes  181  spaced apart. The first heat sealing nodes  171  may form a first heat sealing line L 1 , and the second heat sealing nodes may form a second heat sealing line L 2 . When each of the side walls  12  is bent along the first virtual bending line L 1 , and each of the bottom walls  11  is bent along the second virtual bending line L 2 , a buffer bump  21  is formed between the first virtual bending line L 1  and the second virtual bending line L 2 , two sides of the buffer bump  21  respectively abut against the side wall  12  and the bottom wall  11 , so that the side wall  12  and the bottom wall  11  are adjacent to each other and do not squeeze each other. Based on this structure, the structure of the side wall  12  and the bottom wall  11  can be stabilized, so that the angle of the connection between the side wall and the bottom wall  11  is a right angle shape, so that it can more closely offset the border of the conveying object. 
       FIG. 5  is an appearance schematic diagram of an M-type inflatable bag  1  according to an embodiment of the present invention. In this embodiment, in the first side A, a protective wall  13  forms a hole  19  with a bottom of the side wall  12 . After the M-type inflatable bag  1  packing the conveying object, the conveying object will be boxed, during a delivery preparation stage, the operator will have a box binding procedure, the hole  19  is reserved in the binding process to accommodate the nail (through the box) space. Therefore, the body of the shockproof packing material and the conveying object may not be hurt. 
     At least one embodiment of the present invention, because the structure of the M-type inflatable bag includes the limiting gas column, the distance between the side walls is not expanded outwards due to the extension of the side wall. That is, the limiting gas column provides a function of making the two side walls retract inward, and the two maintain a distance. In this way, the M-type inflatable bag can match the structure of the conveying object. The M-type inflatable bag is set up on the conveying object or to accommodate the conveying object, providing good protection without loosening, and providing effective cushioning force impact, and the ability to absorb shock.
