2. Description of the Related Art Conventionally, as a bag for storing and storing drawings and the like, a bag whose top end is opened by a pair of main surface portions on the front and back sides and a gusset portion that connects side edges and bottom edges of both main surface portions. There is known a structure in which a portion is formed, and further, a binding portion having a binding hole is formed on one side of both main surface portions. In this type of storage bag, both main surface portions and the binding portion are formed of a paperboard as a core material and a cloth material attached to the surface thereof, and the cloth material integrally forms a gusset portion and a lid of an opening. It has been formed in.

This type of storage bag can be carried alone, and when storing drawings or the like, a plurality of storage bags can be stored with a binding cord formed through a binding hole formed in each binding portion as needed. They are linked (co-written) with each other.

Further, when the drawings are stored in the bag portion and the related documents are bound together, the binding cover and the storage bag having the same binding portion are bound together, or the storage bag is Binding is performed by using a binding tool in which a binding unit is fixed between cover sheets of another file.

Further, when a plurality of storage bags containing drawings and the like are bound and stored with a binding cord, they can be tightly united so that they can be securely bound together between the binding portions depending on the storage thickness of each bag portion. A required number of spacers are interposed.

[0006]

Since the above-mentioned conventional storage bag has a structure in which a paperboard as a core material and a cloth material covering the surface of the storage bag are adhered to each other, it is difficult to separate and recycle them and to incinerate them. There is a problem of having to do this.
