A bag includes a front part, a bottom part, a back part and gasset parts. The front part, the bottom part and the back part are unified to be a bag body. Both sides of the bag body are provided with one sides of slide fasteners on hem portions which connect with the gasset parts. The gasset parts are provided with the other sides of the slide fasteners on hem portions thereof. The fasteners are disengaged to release each part to open and spread the bag and engaged to make it up. With the bag being opened and spread substantially flat, objects may be readily received in and taken out of the bag regardless of the size and shape.
