A pouch includes a body formed from a film that defines a generally flat base and an upstanding wall that extends from the base to form an elongate mouth having first and second opposing faces. The upstanding wall has a varying thickness with a first thickness of the upstanding wall at a lower portion of the body being greater than a second thickness of the upstanding wall at an upper portion of the body. The body stands independently in an upright position upon the base when the body is in an expanded position.

1. A pouch comprising: (A) a seamless body having: (a) a first end and a second end, the second end of the body being on an opposite end from the first end of the body;(b) a substantially flat, planar base at the first end of the body; and(c) first and second opposing walls that extend upwardly from
1. A pouch comprising: (A) a seamless body having: (a) a first end and a second end, the second end of the body being on an opposite end from the first end of the body;(b) a substantially flat, planar base at the first end of the body; and(c) first and second opposing walls that extend upwardly from the planar base to form an elongate mouth at the second end of the body, the first and second opposing walls each comprising an upper wall portion and a lower wall portion, the upper wall portions of each of the first and second opposing walls extending to the elongate mouth and including a flexible wall portion, the lower wall portions of each of the first and second opposing walls extending to the planar base; and(B) an elongate closure mechanism being disposed on the flexible wall portions and adjacent to the elongate mouth, the elongate closure mechanism providing a resealable closure for the pouch,wherein the first and second opposing walls of the seamless body have a varying thickness, with (i) the planar base and the lower wall portions of each of the first and second opposing walls having a first thickness, (ii) the upper wall portions of each of the first and second opposing walls having a second thickness, and (iii) the flexible wall portions having a third thickness, the first thickness being greater than the second thickness, and the second thickness being greater than the third thickness,wherein the seamless body stands independently in an upright position upon the planar base when the body is in an expanded position, andwherein the pouch is both flexible and collapsible, such that the pouch can be folded into a substantially flat condition. 2. The pouch of claim 1, wherein the thickness of each of the first and second opposing walls of the seamless body transitions gradually from the first thickness to the second thickness. 3. The pouch of claim 2, wherein the thickness of each of the first and second opposing walls of the seamless body transitions gradually from the second thickness to the third thickness. 4. The pouch of claim 1, wherein the thickness of each of the first and second opposing walls of the seamless body transitions in at least one step from the first thickness to the second thickness. 5. The pouch of claim 4, wherein the thickness of each of the first and second opposing walls of the seamless body transitions in at least one step from the second thickness to the third thickness. 6. The pouch of claim 1, wherein the seamless body includes at least one fold line about which the body is collapsible and expandable. 7. The pouch of claim 1, wherein the first thickness is about three times the thickness of the second thickness. 8. The pouch of claim 1, wherein the substantially flat, planar base has a generally oval shape. 9. The pouch of claim 1, wherein the elongate mouth has first and second opposing faces on the first and second opposing walls, and the elongate closure mechanism includes a first closure profile disposed on the first face and a second closure profile disposed on the second face, and wherein the first closure profile occludes and deoccludes with the second closure profile to provide a substantially leak proof resealable closure for the pouch. 10. The pouch of claim 9, further comprising a slider coupled to the closure mechanism for occluding and deoccluding the closure profiles. 11. The pouch of claim 1, wherein the seamless body has an upper portion that is formed from a first material and a lower portion that is formed from a second material that is more rigid than the first material, to allow the body to stand independently in the upright position upon the substantially flat, planar base, when the body is in the expanded position. 12. The pouch of claim 11, wherein the pouch is formed from a single layer. 13. The pouch of claim 11, wherein the first material has a thickness that is less than the thickness of the second material. 14. The pouch of claim 11, further comprising at least one fold line about which the seamless body is collapsible. 15. The pouch of claim 1, wherein the seamless body is formed from a film. 16. The pouch of the claim 15, wherein the seamless body is formed from a single layer thermoplastic film. 17. The pouch of claim 16, wherein the first thickness is between about six mils and about fifteen mils and the second thickness is between about one mil and about five mils. 18. The pouch of claim 15, wherein the thickness of the film transitions gradually from the first thickness to the second thickness. 19. The pouch of claim 18, wherein the thickness of the film transitions gradually from the second thickness to the third thickness. 20. The pouch of claim 15, wherein the thickness of the film transitions in at least one step from the first thickness to the second thickness. 21. The pouch of claim 20, wherein the thickness of the film transitions in at least one step from the second thickness to the third thickness. 22. The pouch of claim 15, wherein the seamless body further comprises a plurality of hinges, about which the body is collapsible and expandable. 23. The pouch of claim 15, wherein the elongate mouth has first and second opposing faces on the first and second opposing walls, and the elongate closure mechanism includes a first closure profile disposed on the first face and a second closure profile disposed on the second face, and wherein the first closure profile occludes and deoccludes with the second closure profile to provide a substantially leak proof resealable closure for the pouch. 24. The pouch of claim 23, further comprising a slider coupled to the closure mechanism for occluding and deoccluding the closure profiles.
