Tape not pulling back on components causes machine to stop

It is not the feeders having the issue. The tape on the strip of parts does not want to pull up easily. I just wondered if anyone else out there is having the same issue. Thanks for any feedback.

Is this for something permanent? Where is the ground pad located (mid-bank, bank-end etc.)? What is the lead pitch? Are you looking on rerouting this pin some place else? Can you provide a picture of the pad in question?

I've seen 1-mil Kapton tape. Would that work, or would it be too thick? I've never tried it... How thick is the average solder mask?
