Abstract
A plastic or like material liner inserted within a fabric type bulk bag so that the liner is secured in position within the bag with an adhering means along substantially the outer surface of the liner for adhering to the inner most surface of the bulk bag at strategic points, and a second adhering means for adhering the lower portion of the bulk bag to the liner at substantially the point of exit of bulk contained within the bag, so that release bulk from a lower spout would not tend to dislodge the liner from its lined position within the bag. The invention would also include the process for inserting the liner within the bag which would include inserting the liner to the body portion of the bag; closing off the lower most exit chute of the liner; forcing a pressurized air to the liner so that the liner is inflated within the bag; maneuvering the liner within the bag while inflated to assure that the liner is substantially free of creases or void space between the liner and the bag; deflating the bag and liner while the liner is in position within the exterior bag.
