    • A filling material (10) for use in filling hollow spaces in packaging or the like comprising one or more pieces of flexible paper material (12). The paper material has a plurality of individual slits (14, 16) 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 (20) between adjacent slits in the adjacent parallel row of slits. The flexible paper material (12) is expandable by extending the opposing ends (22, 24) 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.
    • 一种填充材料(10),用于填充包括一个或多个柔性纸材料(12)的包装等中的中空空间。 纸材料具有多个单独的狭缝(14,16),其形成为平行间隔的行,其横向从纸材料的一端延伸到纸材的相对端。 相邻交替排中的狭缝位于相邻的平行狭缝行中的相邻狭缝之间的间隔空间(20)附近。 柔性纸材料(12)可通过延伸纸材的相对端部(22,24)而扩展,纸张材料的平行于狭缝排,由此狭缝形成开口阵列,每个开口的大致六边形形状 相同大小 柔性填充纸材料的长度和宽度可以变化。 柔性纸填充材料的结构使其易于储存在不可扩张的位置并且容易地膨胀以用于填充包装中的中空空间。
