ABSTRACT:
A filling material for use in filling hollow spaces in packaging or the like comprising one or more pieces of flexible paper material. The paper material has a plurality of individual slits formed in parallel spaced rows extending transversely from one end of the paper material to the opposing end of the paper material. The slits in adjacent alternate rows are positioned adjacent the interval space between adjacent slits in the adjacent parallel row of slits. The flexible paper material is expandable by extending the opposing ends of the paper material which are parallel to the rows of slits whereby the slits form an array of openings, each opening being generally hexagonal in shape and of the same size. The length and width of the flexible filling paper material can be varied. The construction of the flexible paper filling material provides it to be easily stored in the non-expandable position and easily expanded for use in filling hollow spaces in packaging.
