Abstract: An inexpensive, discardable liner for the storage area of a motor vehicle including a main panel made of durable material. The main panel includes multiple fold lines which enable it to be folded into an enclosure capable of holding various objects. More particularly, the main panel is divided into an integrally attached bottom panel, a back panel, two side panels, and a front panel. The back and front panels each include folding tabs with engage slots formed on the side panels to hold the back, front and side panels in a perpendicularly aligned position. Hook and loop connector strips may be used in place of the tabs and slots. Optional fold lines are also included on the side panels which enable the front panel to be selectively positioned in alignment with the rear seat.
