ABSTRACT:
A bag of the gusseted square-bottom type having a generally rectangular bottom including a rectangular bottom fold portion and a triangular bottom fold portion is made with the triangular fold portion overlapping the rectangular fold portion. The triangular fold portion is sealed at the outermost ends thereof to define an inner enclosed space which communicates with the interior of the bag so that it can be extended from the bag bottom as the bag expands during a microwave cooking operation to form a fin-like extension.
