ABSTRACT:
System and method for packing loose fill materials in bags to form cushions for use in protecting articles in shipping cartons. The bags are produced from a length of flexible plastic tubing which is gathered or bunched to form a coil which is disposed about the outlet of a loose fill dispenser. A section of the tubing is pulled from the coil, and its lower end is closed to form a bag which is then filled with loose fill material dispensed through the outlet. Another section of tubing is then pulled from the coil, and the tubing is drawn together to close the upper end of the first section and the lower end of the second section. The closed ends are secured with tape, and the tubing is severed to separate the first section from the second. The cushions thus formed are placed in the shipping cartons with the articles, and in some embodiments are compressed and reexpanded in conformance with the contour of the articles.
