In their Instrutors manual, Ruth Chabay and Bruce Sherwood said they used
Rite-Aid invisible tape.
Here in Australia, I used a generic brand from the local supermarket and
had no problems.
I've used their text now both for undergraduate science teachers-to-be and
for an inservice Graduate Certificate course.  I found it excellent; my
students say it's one of the best physics text they have encountered, if
not the bes; criteria: easy to read, easy to follow  easy to study from,
helped them understand what was happening
