Abstract: To form a product supporting packaging insert, a substantially rectangular flat blank of a material such as polyproplene foam, corrugated cardboard, or honeycomb cardboard is die cut to form a lateral end segment at one end of the blank, a pair of longitudinal parallel side segments adjoining the lateral end segment, and a longitudinal central segment adjoining the lateral end segment. The central segment of the blank is provided with a tab receptacle at its end facing the end segment and the end segment is provided with a tab facing the end of the blank. To assemble a product supporting packaging insert from the blank, the end segment of the blank is pivoted on fold lines separating it from the side segments and the tab inserted into the tab receptacle.
