thermal tape??

hello all,
i was going through some old boxes and found some stuff given to me by an retired electrician, not much really just lots of heat shrink.. BUT i came across something odd i think it may be like thermal tape/strips or something but im not sure.... please help.
thanks in advance

sorry about the pic quality, i took it on an old iPhone

It is a licorice flavored fruit roll-up

Is it sticky on both sides?

why yes..... yes it is

Similar to this maybe?

It was often used in the older days, when motherboard items did no have clamps. This meant that , as well as cooling, it helped, for example, to "glue" the fan to the top of the CPU.
I believe its actual cooling effect was minimal, but with mor knowledge now of cooling cvompounds, it could be worthwhile for a motivated company to experiment with it again.

You see this kind of stuff on Heatsinks and the like. To be honest it's not much cop.. The TIM you purchase in tubes is far better..
I always use OCZ freeze as it's superior quality to other Thermal pastes out there..
