A flexible container ( 10 ) has a base ( 12 ) that includes a bottom ( 20 ), side walls ( 22, 24, 26, 28 ) and an interior ( 30 ), the bottom defining a substantially flat planar surface when the container houses product and the container rests thereon, an upper panel portion ( 14 ), that is adapted to be received within the interior of the base portion and includes side panels that define a closure member ( 60, 62 ). The upper panel is constructed and arranged to define a substantially flat surface ( 72 ) when the closure member is closed and portions of the upper panel are folded over. The upper panel includes a portion that is sealed to the base portion. A pair of handles ( 16, 18 ) may be secured to the base portion. The flat top and flat bottom allow for vertical stacking of the filled containers. The container may be manufactured from a flat sheet of plastic material having a width substantially equal to a length of the base portion, by indexing the flat sheet in intervals equal to a width or more of the base portion; bonding handles at one end to the sheet; applying closure means to a free end of each of the pair of panels; and forming the flat sheet, panels and pair of handles into the flexible container.
