Abstract: A packing insert is provided which is formed from a blank of foldable sheet material and is adapted to be disposed within a multi-sided container to position a product in a predetermined relation within the container interior. The insert includes a base panel having a peripheral configuration conforming substantially to the area defined by the side walls of the container. Foldably connected to the periphery of the base panel and disposed adjacent to predetermined corners thereof are a plurality of support units. Each unit has a first section thereof which overlies a surface of the base panel and a second section which projects therefrom. Each support unit is held in a set-up condition by an elongated retainer member which is struck out from the base panel.
