If you put the book in the airplane box, because the airplane box is not actually sealed, there will be air in the airplane box, so the book will turn yellow in the airplane box. The shape of the airplane box is similar to that of an airplane. Made of ordinary cardboard and color printed cardboard, it can be used simply by folding, which is convenient and fast.
There are two obvious differences between airplane boxes and traditional packaging boxes.
First, the flat box is relatively strong and has good impact resistance.
Second, they are often designed more beautifully.
Even if you don't put books, you can put umbrellas, snacks, cups, coats and other sundries, which is very convenient. Secondly, if you are an office worker, it is also a good choice to convert the plane box into a clothes storage box. Especially in the south, clothes placed directly in the closet are easy to get wet, and it will be better to put them in a box, which is not easy to get dusty.
