Abstract: The invention provides a symmetrical, corrugated fibreboard blank which can be folded into an insert configured to be received within a shipping container. A product can be protected and secured by the insert. The symmetrical design results in ease and speed of assembly regardless of the orientation of the blank along the end user's packaging assembly line. The 5-sided shape of the insert produces void spaces that the products cannot reach, thus creating natural air cells within the insert. The ends, tabs and panels of the insert also provide for minimal movement of the product within the insert and further provide layers of cushioning upon impact. The insert can secure a variety of different sized products, is environmentally friendly, inexpensive and space-saving.
