Abstract: A pouch for sterilized materials is formed from two webs positioned face-to-face attached around portions of their edges by heat fusion, thereby forming a pouch having an interior cavity and a mouth being an unsealed portion of the webs along a top edge. An interior boundary line along the inside of the seal area has a wavy configuration which includes a series of inward-facing peaks and valleys. Thus, when the cross-seal is applied to close the pouch, the overlap of the seal areas along the interior boundary is along a wavy line and therefore microbial contamination is inhibited by this tortuous path. A similar tortuous path for preventing microbial contamination is provided in the type of the pouch having a breather panel by cutting a wavy configuration into the side edge of the breather panel web before it is spliced and fused to the other pouch webs.
