An internal support member for a shrink wrapped package of identical articles arranged in a layer or layers on a base comprises a single generally rectangular sheet of relatively rigid material formed with at least two preferably six parallel folds that extend vertically when the sheet is stood on edge on the base. The folds define compressive load-bearing side portions which are disposed longitudinally and laterally between the articles in the layer to provide a stable non-tilting support for a similar package stacked thereon.

In a package comprising a base, a shrink wrapped array of generally identical articles arranged in at least one layer so as to be supported on said base and a support member disposed edgewise on said base to resist compressive forces directed perpendicular to the layer, the improvement in which the support member is of integral, one-piece construction consisting of a generally rectangular single sheet of thin relatively rigid material folded along six generally parallel lines arranged in two symmetrically disposed groups, said lines extending the full height of the support member and substantially perpendicular from the edge on which the support member stands to the opposed distal edge thereof, said lines defining a planar central portion, two inner intermediate load bearing side portions respectively attached to and along the opposite side edges of the central portion by means of infolds, said inner intermediate load bearing side portions projecting to a first side of the plane of the central portion, two outer intermediate load bearing side portions respectively attached to and along the outer side edges of the inner intermediate side portions by outfolds, said outer intermediate load bearing side portions projecting beyond the plane of the central portion to the second side thereof, said load bearing side portions being formed with distal edges that lie in a plane parallel to the base, the support member being located in the interstices of the array such that a longitudinal and two lateral interstitial planes thereof are respectively coincident with the central portion and the outer intermediate load bearing side portions of the support member whereby the load bearing side portions are self adjustably movable while remaining perpendicular the base and the distal edges of the load bearing side portions provide a stable non-tilting support for another such package placed on the distal edges, and whereby the support member is substantially shielded from external side view while no article at the periphery of the layer is completely shielded from external side view.
