    Yes, plus if you are in a hurry when processing you can just snip it off and process with it attached, after all, thats what is was made for.

    It is a tape for securing and labeling frozen food packages. It is similar to paint masking tape.

    Wait, I only use a dark bag so I've never SEEN myself spooling my film unto a developing reel, but at the end of a 120 is roll has tape on the backing paper, I always peel it off the film at the end of the roll. Do you think THAT tape would also create static sparks?

    Yes, it does. As does tearing the tape, which is what I do, but I've never *noticed* a fogging problem doing it.

    It does and I've seen it, although I can't say if it affected my 120 roll or not. Since then though, I've always either A) peeled it off the film really slowly - no sparks or B) leave it on the film and carefully peel off the backing paper before folding it over the film end (which actually helps me sometimes when I have problems loading the Patterson 120 spool).

    Almost all tape does it. It is a function of the release process when tape is pulled away from what it is stuck to.

    If the film is sensitive enough, you will see the marks. It can usually be seen right at the spot where you peeled the tape away but sometimes it is seen as a grayish "halo" of diffuse fog in a ring around the peel off spot.

    If it is far enough away, there is no problem, but if it is close to a roll of film or the entire bulk roll for some reason, then you have a problem.

    The adhesive in freezer tape adheres better than masking tape and does not lose its hold when exposed to moisture or low temperature. The problem with masking tape is that it is designed to be easily removed and hence does not stick very well. It is designed to cover and not to hold.

    Aren't the sparks made by peeling tape an example of triboluminescence as opposed to static electricity?
    (e.g. The same effect that makes Lifesavers candy spark when you chew them.)

    Randy, you are correct. It is not static electricity, but the breaking of chemical bonds. That is not to say that static electricity cannot take place, and if it does it is a far worse problem than the triboluminescence.
