In a seventh aspect of the present invention, the resin film has four regions where the first band and the second band intersect and overlap, and among the four regions, a top surface of the aggregate is provided. The collective package according to the sixth aspect, wherein the first band and the second band are bonded to each other in two side areas and/or two bottom areas.

In the seventh aspect, the second band of the first band intersects and overlaps with the first band in two areas on the top side and/or two areas on the bottom side of the aggregate. By adhering the second band to each other, the assembly can be bound in a state where the two bands constituting the first band and the second band are fixed to each other. Therefore, in the seventh aspect, it is possible to further suppress displacement of the accumulated aggregates.

In the seventh aspect, a part of the second band can constitute a handle of the collective package between two regions where the first band and the second band are mutually adhered. Since both ends of the handle of the collective package formed from a part of the second band are fixed to the first band, the handle of the collective package can be held more stably as a handle for the collective package.

An eighth aspect of the present invention is that the second band has a base wrapped around the aggregate and an extension that overlaps the base on at least a top surface and/or a side surface of the aggregate. The assembled package according to any one of the second to fourth aspects.

In the eighth aspect, by wrapping the base of the second band around the aggregate, the base can simultaneously bind the aggregate and the first band wrapped around the aggregate. Furthermore, by overlapping the base of the second band, the extension of the second band can function as a handle for the collective package separately from the base. Therefore, in the eighth aspect, even if the extension part is used as a handle for the assembled package, the assembly can be kept tied together by the base.

A ninth aspect of the present invention is the collective package according to the eighth aspect, wherein both ends of the extension are bonded to the base.

In the ninth aspect, both ends of the extension of the second band are bonded to the base of the second band, so that the extension of the second band forms a collective package between both ends of the second band. can be configured with a handle. Since both ends of the handle of the collective package constituted by the extension of the second band are fixed to the first band, the handle of the collective package can be gripped more stably as a handle of the collective package.

A tenth aspect is the aggregate package according to the tenth aspect, wherein the aggregate is shrink-wrapped, and at least the inner side and/or end surface of the aggregate is exposed. In the tenth aspect, by shrink-wrapping the assembly so that at least the inside of the side surface and/or end surface is exposed, at least the corner of the assembly can be covered with the resin film. Therefore, while reducing the amount of resin film used, it is possible to suppress displacement of the accumulated aggregate.

An eleventh aspect of the present invention is the collective package according to the tenth aspect, wherein the aggregate is an aggregate in which a plurality of the sheet storage boxes are stacked in a plurality of rows. In the eleventh aspect, even if the assembly is an assembly in which a plurality of sheet storage boxes are stacked in a plurality of rows, the assembly may be shrink-wrapped so that at least the inner side and/or end surface of the assembly is exposed. , while reducing the amount of resin film used, it is possible to suppress displacement of the accumulated aggregate.
