Claim:
An article of commerce comprising: (a) a longitudinally continuous web having a longitudinal down-web direction, a lateral cross-web direction, and lateral sides, with: (i) superimposed first and second layers secured together by spaced apart lateral seals and longitudinal seals spaced along each longitudinal edge of the web; wherein: (A) the first layer comprises a gas permeable microbial barrier layer, and (B) the second layer comprises a thermoplastic gas impermeable layer, (ii) longitudinally spaced laterally extending lines of weakness in one of the first or second layer said lines of weakness being adjacent to one of said lateral seals, (iii) longitudinally spaced laterally extending lines of separation in the other first or second layer with the lines of separation paired with the lines of weakness wherein upon detachment of the web along the line of weakness access is created to a space between the first layer and the second layer on a first side of the line of weakness while maintaining the adjacent seal along a second side of the line of weakness; and, (b) the seals between the layers being peelable seals delineating sides and an end of the space between the first and second layer for receiving a product to be sterilized by sterilizing gas passed through the permeable layer.
