● Bonzer Indicator Tapes are self-adhering tapes with a chemical indicator printed on one side. They can be used to seal packages that are to be sterilized. After processing, the printing will change color and provide a clear indication that the package has been processed. ● The Tape indicator colour demonstrates at a glance whether or not the product has gone through the sterilization process, making it easy for sterilization facilities to ensure that products have been exposed correctly to the sterilization process.
