(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.

Abstract
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.
