ABSTRACT:
A structure for a food bag that is suitable for a larger than usual sized bag is described as being formed of two sections of a flexible material. The two sections of flexible material are arranged one over the other and sealed around their periphery. Another sealing line is located along at least one side spaced from the one periphery line to form an elongated stiffening compartment when filled with a suitable gas, such as air, under pressure. The remaining space between the sealed sections forms a food compartment that is maintained in an erect, upright position by the elongated stiffening compartment.
