ABSTRACT:
A sterilizable pouch is provided with first and second opposing webs which are initially sealed together except for a region defining an open mouth. At least one of the webs has a strip of adhesive adjacent the mouth with a peelable release strip superposed upon and adhering to the adhesive strip for masking the adhesive strip from external contact before the pouch is closed and sealed. The peelable release strip includes an indicator means for indicating its exposure to a predetermined sterilization condition. The indicator means has an initial appearance signifying that the indicator means has not been subjected to the predetermined sterilization condition and is adapted to change to a final appearance after exposure to the predetermined sterilization condition for indicating such exposure. To use the pouch, an article is inserted within the pouch, the peelable release strip is removed from the adhesive and placed within the pouch next to the article, and the adhesive strip on one of the webs is brought into contact with the other web to close the mouth of the pouch. When the pouch is sterilized, the indicator means on the peelable release strip within the pouch changes appearance to indicate the attainment of the predetermined sterilization condition within the pouch.
