A package of thin, flexible material for positioning an article contained within the package has an exterior container having generally the shape of a rectangular box made with first and second opposed main panel pairs joined at ninety degrees to form a tube of rectangular cross-section and a pair of end closures at opposite ends of said tube. An internal positioning frame exists within the exterior container. The internal positioning frame has a pair of generally parallel positioning panels, each such positioning panel being parallel to the first pair of main panels and both such positioning panels being connected to one of the second pair of main panels. A first positioning strut is connected between the parallel positioning panels and lies generally perpendicular to each of the parallel positioning panels and in spaced, generally parallel relation to the second pair of main panels. A second positioning strut is connected between the first positioning strut and at least one of the first pair of main panels. The second positioning strut lies generally parallel to said parallel positioning panels and in a plane intermediate the planes of said parallel positioning panels.
