A fiber free, fast breathing tear strip for a gas sterilizable package which comprises a sandwich of a gas permeable membrane impervious to bacteria, and a perforated, or slit plastic sheet. The sandwich is peelably sealed around the access opening of a bag. One seam of the tear strip can be made non-peelable so that the tear strip becomes non-detachable. Particular embodiments of gas sterilizable packages which utilize the invented tear strip are disclosed. |
