Transfer Express, and I'm sure others, sell a blue tape that is heat resistant, especially for this purpose.Steve
I got good heat tape at cheaper prices online from Temu. Remember, it has been advised to not install and use the Temu app on the phone.But also, take a little time and figure just how much it adds to the actual job. It's probably pennies, that you can absorb into your total cost and figure into your price easily.Don't become "penny wise and pound foolish". It will eventually bite you in the butt.Oh, and I don't think it's called transfer tape, as that's what's used to apply vinyl graphics. Just look for heat tape.
I could be wrong but I think it's Kapton tape used in electronics.
I bought clear tape that works well on AliExpress cost about $2 a roll. Comes in different widths. Rolls about 25m
This is what I bought, comes in different widths and works well. Really cheap
