ABSTRACT:
A bag construction includes first and second opposed panel sections. Each of the panel sections have first and second opposite side edges. The panel sections are secured to one another along at least a portion of the first and second opposite side edges by first and second side seals, to define a bag construction interior. The first and second side seals each have an inner edge portion adjacent to the bag construction interior. The first side seal inner edge portion has at least one non-linear edge section extending over a part of the first side seal inner edge portion. The non-linear edge may include an edge with a plurality of spaced inwardly directed projections, or an edge with curved portions, or an undulated edge. The seals may be used in a variety of packaging arrangements, and help to provide an arrangement which will stand upright when filled or at least partially filled with material.
