A nonwoven fabric bag includes: a bag body; and a pair of handles. A fabric sheet is folded in two. A bottom of the bag is formed by a sheet portion including the fold line. Side edges of the opposing folded halves of the sheet are bonded together on right and left sides to form a bag. A sheet portion along a peripheral edge of an opening of the bag is folded inward and bonded to form a double-layer portion, thereby forming the bag body. Two strips are attached to the double-layer portion, thereby forming the pair of handles. The side edges are bonded by impulse heat sealing. The peripheral edge of the opening and a vicinity thereof, and a part connecting to the fold line are sewn. The double-layer portion is bonded by discontinuous ultrasonic sealing. Attachment portions between the double-layer portion and the handles are sewn. |
