ABSTRACT:
A plastic bag formed from two panels of substantially rectangular plastic film that includes an oxygen barrier and a heat sealable surface. The panels are joined by three edges with the heat sealable surfaces facing one another. At least one of the panels includes a number of air channels. Each of the air channels has first and second opposing ends. The first end of each air channel is adjacent an unjoined edge of the panel. Each air channel extends toward the joined edges from the first end to the second end. The second end of each air channel is closer to the unjoined edge than the joined edges. Each air channel is spaced apart from an adjacent air channel by no more than a first distance. Each second end is spaced apart from an adjacent second end by a second distance that is greater than the first distance.
