A collapsible and expandable void filler comprising a plurality of first and second corrugated panels alternately stacked one on another and adhered together, said first panel being generally V-shaped in the expanded condition and comprising a central glue section, a pair of glue flaps at the outboard edges thereof, and a pair of long panels extending therebetween, said second panel being generally W-shaped in the expanded condition and comprising a central glue section, a pair of lower side glue sections, a pair of upper glue flaps, a pair of long panels extending between said lower side glue sections and said pair of said upper glue flaps, and a pair of long panels extending between said lower side glue sections and said central glue section,

• said central glue section of said first panel being adhered to said central glue section of said second panel,
• said glue flaps of said first panel being laminated between the lower side glue section of said second panel and the upper glue flaps of an adjacent second panel,
• in the expanded condition in use said long panels of said first panel and said long panels of said second panel extending between said lower side glue sections and said central glue sections forming a vertical array of stacked diamond-shaped cells, and said pair of long panels extending between said lower side glue sections and said pair of upper glue flaps of said second section forming therewith a vertical array of stacked triangle-shaped cells adjacent to said diamond-shaped cells.
