Explanation
Iron-on thermal tape indicates it has reached the correct temperature by changing color. In the specific instance of green-dotted iron-on thermal tape, once the tape reaches the correct temperature, those green dots change to black. It’s a visual indication to tell that it has been heated correctly. Therefore, when these tapes are heated sufficiently, they undergo this coloration change.
