the partition to be utilized in one embodiment the horizontal hinges extend the length of the panel and allow the panels to be fan folded in either direction in a preferred embodiment the hinge is made of a flexible polymeric material such as polystyrene polyethylene or polypropylene more preferably the hinge is a strip of a polyethylene or polypropylene film material having a width in the range of from 3 to 5 inches and a thickness in the range of from 0 0625 to 0 250 inches that is adhered to either the interior or exterior side of the panels along each joint with enough space provided between the panels so that each panel may be caused to lie flat against an adjacent panel when the partition is fan folded along the joints preferably the hinges have a tabbed portion that extends beyond the edges of the panel joint by a distance width of no greater than the thickness of the panels preferably the tabbed portions have a width of at least 0 5 times the thickness of the panels when the partition is opened and a tabbed portion is bent in a direction so that it lies flat against the side edge of the partition or partition door thereby forming an l shaped portion around a corner of the partition or door the position of the l shaped portion against a two panel.
