Anyone know what the official name of those silver / AL looking tape on the back of LCD panels? I'm planning to take apart an older iMac 27 inch 1440 panel because dust got in between the white light emitting part and the actual color LCD panel. The unit has silver tape around the edges as part of the seal. Youtube tutorial didn't mention the official name. Searching on Amazon is showing me duct repair silver tape which I have and it doesn't have the right feel to it (too thick and rigid).
