[0076] A cloth-plastic composite surface layer is cut into elongated squares, and then sealed end to end to form a square peripheral layer 53, on which an airtight zipper 2 is arranged, the length of which is close to or greater than the length of the three continuous surfaces of the square peripheral layer 53, so that the opening is larger and it is more convenient to load and take out the stored items.

[0077] The peripheral layer 53 is provided with a handle 8 and a zipper 9, and then the cloth-plastic composite surface layer with the same area is cut to form the top layer 51 and the bottom layer 52.
