ABSTRACT:
Sterilization indicator tapes utilizing moisture-resistant, water-dispersible, pressure sensitive adhesives are provided. The indicator tapes comprise a non-water-dispersible backing having a sterilization indicator thereon, which is coated on at least one side with the moisture-resistant, water-dispersible, pressure sensitive adhesive. The indicator tapes are useful to maintain a sterilization wrapper containing articles to be sterilized in a closed position during sterilization, and normal pre- and post-sterilization handling, while also providing a means to indicate if the wrapped articles have passed through a sterilization cycle. After use, the adhesives coating the indicator tapes disperse in aqueous alkali solutions, such as are found in commercial laundries, while the backing remains intact. Methods of making and using the indicator tapes are also provided.
