I suggest finding something else, electrical tape starts coming off after a few years, leaving behind sticky residue that's impossible to remove without some kind of solvent. Same goes for masking tape.
I have 20 year old white duct tape on containers in my basement that has never peeled. It takes ink pretty well.
Obviously hell if you need to remove it, but we're talking about permanent labels. If I need to change a label I just put on a fresh layer of tape.
I assume he labels the bag and never has the need to remove it (you just take a new bag). Edit: Nope I was wrong. Bad bad bad
I use wraparound cable labels[0] which seem to work ok (although do end up sliding up and down the cable to some extent.)
