1. A method of preparing pouch arrangements having:
- first and second opposed panel sections, a bottom edge;
a base gusset member;
a rib and through closure arrangement; and
, a gas filter oriented in one of the panel sections;
said method including the steps of;
(a) providing a continuous full web of panel section material;
(b) splitting the full web into first and second continuous half webs of panel section material;
(c) forming a continuous feed of pouch blank by;
(i) directing the first and second continuous half webs into juxtaposed orientation with one another to form the continuous feed of pouch blank with;
front and back faces; and
, first and second, opposite, longitudinal side edges;
(ii) orienting a first continuous base gusset between the first and second half webs along the first longitudinal side edge;
(iii) orienting a second continuous base gusset between the first and second half webs along the second longitudinal side edge;
(iv) orienting first and second continuous strips of rib and trough closure arrangement;
(A) aligned substantially parallel to one anther and substantially parallel to the first and second longitudinal side edges; and
(B) positioned between the first and second half webs and also between the first and second continuous base gussets;
(d) dealing the continuous feed of pouch blank to form a plurality of sections therein comprising pouch arrangements joined to one another with;
(i) a top end of each pouch arrangement joined to a top end of another pouch arrangement along a center line of the continuous feed, the center line being oriented between and substantially parallel to the first and second rib and through closure arrangements;
(ii) a side edge of each pouch arrangement joined to a side edge of a next pouch arrangement; and
(e) cutting the pouch blank into individual ones of the pouch arrangements;
(f) said method being further characterized by steps of;
(i) punching a plurality of pores in the first continuous half web such that pouch arrangements therefrom will each have a pore positioned a first distance from the rib and trough closure arrangement therein and toward the bottom edge thereof;
said first distance being about 2% to about 30% of a distance between the rib and trough closure arrangement and the bottom end edge of the pouch arrangement; and
(ii) orienting a gas filter arrangement over the pore in each pouch arrangement.

Abstract
A vented pouch is described which comprises: first and second opposed panels; a base gusset; and, a gas filter arrangement oriented in one of the panels. The gusset member is preferably oriented between the panels, along edges thereof, to form a base by which the pouch can be stood-up during use. Preferably, the pouch is provided with a rib and trough closure arrangement extending thereacross. A preferred method for formation of preferred such pouches is also described.
