ABSTRACT:
An improved material packaging system having a plurality of nested liners that are removably attached to each other to form a unitary liner structure. A receptacle having a first attachment device for detachably securing the unitary liner structure to the receptacle is set forth. The unitary liner structure has a second attachment device for detachably securing the second attachment device to the first attachment device of the receptacle. Each of the liners has a pull grip for gripping the liner to remove the liner from the unitary liner structure and perforations disposed between the pull grip and the second attachment device for tearing the liner when a tearing force is applied thereto. An uppermost liner of the plurality of liners can thus be removed from the unitary liner structure without substantially disturbing the positioning of underlying liners by gripping and pulling the pull grip of the uppermost liner to apply the tearing force to the perforations of the uppermost liner. The second attachment device extends around an entire circumference of the unitary liner structure and can be a drawstring. The second attachment device can be a sheath for retaining the drawstring. Both the sheath and the drawstring extending around an entire circumference of the unitary liner structure as well as the perforations being disposed in a line are also taught.
