ABSTRACT:
The present invention has an object to provide a disc storage bag being able to prevent a disc stored therein from falling off from the bag. The disc storage bag of the invention comprises a first sheet made of a nonwoven fabric, a second sheet disposed at least on one surface of the first sheet for covering part of the surface on one end side of the first sheet, and a third sheet for covering part of the same surface of the first sheet on the other end side thereof, whereby the first sheet forms a disc storage portion jointly with the second and third sheets. The first and second sheets are closed at the one end and opposite lateral sides for forming a bag portion therebetween. The third sheet is connected to the first sheet at the other end side and further bonded by heat-sealing to the first sheet at a pair of suitable portions positioned at the opposite lateral sides on the other end side or somewhat inward from the lateral sides, said portions also being positioned somewhat distant from the connected portion of the first and third sheets on the other end side toward the one end side of the first sheet.
