Both sides of the first shielding portion 12 are adhered to the surface of the bottom wall 11 by means of heat sealing, and a first nesting space S1 is formed between the first shielding portion 12 and the bottom wall 11.

[0031] The second shielding portion 13 includes a plurality of second shielding air columns 131. The second shielding portion 13 and the bottom wall 11 are integrally connected to a lower side of the bottom wall 11, and the second shielding portion 13 is folded above the surface of the bottom wall 11 by a second folding line L2. Both sides of the second shielding portion 13 are adhered to the surface of the bottom wall 11 by means of heat sealing, and a second nesting space S2 is formed between the second shielding portion 13 and the bottom wall 11.

[0032] The first nesting space S1 and the second nesting space S2 can be separately sleeved on a part of a transportation object. For example, in an embodiment, the transportation object is a panel 2. In an embodiment, the bottom wall 11, the first shielding portion 12 and the second shielding portion 13 can be stacked by a plurality of diaphragms by means of heat sealing and inflation.

[0033] The limiting film 14 is stacked above the bottom wall 11, that is, between the first shielding portion 12 and the second shielding portion 13, including a body 141 and a reversed portion 142. The reversed portion 142 is located in the second nesting space S2, and the reversed portion 142 is connected to a bottom end of the body 141 and is folded above a top surface of the body 141 by a folding line L3. In other words, the reversed portion 142 is folded by the folding line L3 from a bottom of the limiting film 14.

[0034] The bottom wall 11 further includes two outer longitudinal heat sealing lines H1 located on both sides of the bottom wall 11, and the outer longitudinal heat sealing lines separately adhere the reversed portion 142, the body 141 and an inner wall surface of the second shielding portion 13 to the bottom wall 11.
