P.S.
mylar/plastic was used for read many tapes. That is a tape that is going to be red many
times and usually holds some critical program. The center sprocket really could eat up
paper tapes. That’s why some material with durability was needed.

There’s really a disconnect on between reading and punching paper tape.
For making blank tape that can be used in a punch, you can cut a roll of something down
to a proper width, but the paper has to be thicker than cashiers paper. The real trick is
that the paper has to be perforated in the middle before use. That’s how it’s “dragged”
thru the punch/reader. I haven’t seen anyone mention how to do that.
If you can manage to do that, then you could also oil the paper and use it on a punch.

the punches weren't so keen. IIRC they were run slowly for copying to plastic and
cleaned afterwards.
