Battery packaging boxes are used to package batteries. After multiple battery packaging boxes are palletized, they need to be wrapped with a roll film, which helps to carry out stable handling and coordination;

[0003] The utility model with the publication number of CN218578323U discloses a battery packaging box, including a box body, an upper box cover is arranged on the top of the box body, and a lower box cover is arranged at the bottom. The upper box cover and the lower box cover are both connected to the box body through packing belts; pallets, the number of the pallets is multiple and they are stacked in the box body.
