A polymeric film bag having first and second panels that are joined to each other along a pair of opposing sides and a bottom bridging the opposing sides. Each of the first and second panels have an original width. Extending inwardly from near or at one of the pair of opposing sides is a first narrowing seal. The first narrowing seal seals the first and second panels together such that a second width of the first and second panels is created that is smaller than the original widths of the first and second panels.

What is claimed is: 1. A polymeric bag, the polymeric bag comprising: a first panel and a second panel each having an original width and a length, the first and second panels joined along a pair of opposing sides and a closed bottom extending between said sides defining a top opening, each panel having at least one tying flap portion extending beyond the top opening between the opposing sides and opposite the bottom, a first narrowing seal joining adjacent portions of the first and second panels; and a second narrowing seal joining adjacent portions of the first and second panels, the first and second narrowing seals disposed proximate or at the opposing sides and at least one of the first and second narrowing seals having a first portion extending inwardly and generally downwardly and a second portion extending outwardly and generally downwardly to define a second width between the seals, such that said second width is smaller than said original width between the opposing sides, the first and second narrowing seals each being located in its entirety proximate the top opening. 2. The polymeric bag as in claim 1, wherein the first and second panels are formed from two separate polymeric sheets. 3. The polymeric bag as in claim 1, wherein the first and second panels are formed from an integral folded sheet. 4. The polymeric bag as in claim 1, wherein at least one of the narrowing seals arcuate or triangular in shape. 5. The polymeric bag as in claim 2, wherein the narrowing seals are formed by either heat sealing or adhering the first and second panels. 6. A polymeric bag, the polymeric bag comprising: a first panel and a second panel each having an original width and a length, the first and second panels joined along a pair of opposing sides and a closed bottom extending between said sides, defining a top opening between the opposing sides and opposite the bottom, each panel having at least one tying flap portion extending beyond the original length and proximate the top opening, the tying flap portion capable of being folded downward in opposite directions, a first narrowing seal joining adjacent portions of the first and second panels; and a second narrowing seal joining adjacent portions of the first and second panels, the first and second narrowing seals disposed proximate or at the opposing sides and at least one of the first and second narrowing seals having a first portion extending inwardly and generally downwardly and a second portion extending outwardly to define a second width between the seals, such that said second width is smaller than said original width between the opposing sides, the narrowing seals being disposed closer in proximity to the top than to the bottom. 7. The polymeric bag as in claim 6, wherein the first and second panels are formed from two separate polymeric sheets. 8. The polymeric bag as in claim 6, wherein the first and second panels are formed from an integral folded sheet. 9. The polymeric bag as in claim 6, wherein the first and second panels further define at least one tying flap proximate the top opening. 10. The polymeric bag as in claim 6, wherein the narrowing seals extend initially inwardly from said bag sides and extending generally downwardly before extending back to bag sides. 11. The polymeric bag as in claim 6, wherein the narrowing seals progressively extend towards the bottom.
