A support frame for a flexible plastic bag which can support the bag in an open-mouthed manner both upright and sideways, the frame having a pair of legs and pivoting leg/handle, the frame being polygonal and composed of a base member, a pair of end members connected perpendicularly to the base member, a pair of angle members connected at an angle less than 90 degrees to the end members, and a top member connected to the angle members, where the top member is less than half the length of the base member to define a pair of corners which act as tensioning members against the lip of the bag when the leg/handle is pivoted to a position parallel to the frame to prevent the bag from being forced off the frame.
