Peel-off pressure-sensitive chemical indicator labels for steam or dry heat sterilization processes that verify sterilization exposure. 

Chemical Indicator for steam is printed with a steam chemical indicator that turns from yellow to dark brown or black in all steam sterilization cycles including 250°F/121°C and 270°F/132°C.

Chemical indicators on the labels can be used for exposure control monitoring which assures the operator handling the processed items that the pack has been exposed to the sterilization process without the need to open the pack or check load control records.
