    Triboluminescence is caused when you pull the tape at the end of a film roll away from the film. The energy releases what appear to be small lightning bolts. Film is sensitive to this.

    HOWEVER, true static electricity takes place in a dry lab when you unroll the film itself and discharge a built up static charge between your body or a reel and the film. Film is much more sensitive to this. In fact, this is why film is coated with an antistatic material incorporated int it.

    Thanks PE, I was referring to the fact you said the scotch tape light flashes were due to static electricity. As you wrote above and the links I gave suggest they are due to triboluminescence.
    Also, you correctly pointed out that static discharge can be caused by the film unrolling.

    Yeah, I admit that it can be either depending on the humidity. You are right though.

    Thanks.
