illustrated in Figure 4 at 150. Bag arrangement 150 includes first and second opposed
panel sections 152 and 154. Each of the first and second panel sections 152, 154
include a first end edge 156 at a first end 158 of the bag arrangement 150 and a
second end edge 160 at a second end 162 of the bag arrangement 150. Extending
between the first and second end edges 156, 160 are opposite side edges 164, 166.
First and second panel sections 152, 154 are secured to one another along portions of
side edges 164, 166 preferably by means of seals 192, 194. Seals 192, 194 extend
along side edges 164, 166, respectively, between first end 158 and points 196, 198,
where a gusset 168 intersects with the first and second panel sections 152, 154. Each
of first and second seals 192, 194 have an inner edge portion 200, 202 preferably
including a nonlinear configuration 204 along the inner edge portions 200, 202. Inner
edge portions 200, 202 may include a plurality of spaced inwardly directed projections
206 or a plurality of spaced outwardly directed recesses 208, such as those illustrated
in Figures 5-7. As shown in Figure 4, the inwardly directed projections 206 on first seal
192 are positioned opposite the inwardly directed projections 206 on second seal 194
and the outwardly directed recesses 208 on first seal 192 are positioned opposite the
outwardly directed recesses 208 on second seal 194. When bag arrangement 150 is
filled or partially filled with material, the non-linear edges in bag arrangement 150
reduces the tendency of the side edges 164, 166 from buckling or doubling over, often
resulting in about a straight line along side edges 164, 166.
