Abstract:
Heat seal performance is enhanced at a portion of a pleated free-standing packaging
material where the rib intersects the pleat perpendicularly. Furthermore,
free-standing stability of the pleated free-standing packaging material is
enhanced by bending the portion where the rib intersects the pleat perpendicularly
to provide a sharper acute angle, thus imparting excellent design. The pleated
free-standing packaging bag having a principal rafter type ribs in the vertical
direction of the packaging bag with the inner surfaces being bonded at the edge
of the packaging material where at least one pleat is drawn by folding trebly in
a stripe form in the direction perpendicular to the vertical direction of the
packaging bag and by bonding the inner surfaces at the folded portion, characterized
in that at least a pleat formed at the ridge formed by the folded base portion and
the outer circumferential portion is extended from the outer circumferential
portion to form the same plane, the base portion and the upper end on the backside
of the pleat are formed substantially at a right angle, and a cut is formed at a portion
where the pleat intersects the rib.
