    Bulk loading adhesive tape

    What kind of adhesive tape is recommended to avoid electrostatic sparkes while bulk loading?

    I use ordinary masking tape - the kind used by those painting a section of wood who do not want the paint to spread. Never found that to have generated sparks

    I use Scotch tape, precut before I go dark. I stick the ends to the counter top in a row. I pluck them off as needed. I never get a tearoff in-camera as was the case with previous tapes. when ready to process, I cut the film from the casette to avoid problems.

    I put the tape around the spool and tape each end to one side of the film to form a firm bond.

    I've used both blue painters tape and scotch tape. The scotch take makes blue sparks, which is amusing but harmless.
    f/22 and be there.

    24mm masking tape is the perfect width for 35mm film.

    Black gaffer's tape.

    A long enough strip to go all the way around the spool and attach to both sides.
    Haven't seen it spark. It won't pull off and it's easy to tear in the dark.

    Sorry, but not true. The blue "sparks" can cause marks and lines on film as you pull it away from the film or from anything nearby the film such as the original roll. That is why I cut mine.

    Exactly PE. Right on.
    That's what happened to me last night. I messed up with a pre-cut adhesive tape (I have a red 3M adhesive tape - core series 2 1300) right on the spool (both estremities of the tape decided to stick together at one point). When I tried to tear them apart: bang. A rather dim but discernable spark. With the 17mt bulk roll near! Hope I didn't ruined anything...

    Interestingly enough, most tapes cause this problem, but with colored backing it is difficult to see, even in the dark.

    Scotch tape and similar products show it quite well being transparent.
