By a flexible sheet made of , with the surrounding a limited amount of openings.And the surrounding collocation is a closed area.Enclosed area has induced in perpendicular to the direction of the bag open extensibility, thus extending in a closed area material, can easily form handles tether.Handle tether tied together to form for overall closed.Extensibility induced by double area network with different extension mode.Double area network also has the increase of grasping the advantages of the surface to form a handle tether.
