Sourcing Metal cassettes except spooling with tape

Hello everyone, I am sourcing metal cassettes 35mm for 2 holed film (reflx lab sells a tool for that), otherwise tell me another technique to put film on spool, everything but not tape.
The cassettes can or not be custom with my own design. I dont want tape i want it more professional like factory made. Reflx lab and company on alibaba only do tape based spooling for metal cassettes.

Best regards

Wouldn't you be able to buy their plastic cassettes with spools included and use the technique shown in the video on this page, but insert their plastic spool into your own metal cassette? Unless I am not understanding what you mean.

It's been a while since I popped open a factory loaded B&W film cassette, but once upon a time, the factory loaded film was taped onto the spool - the tape goes on one side of the film, around the spool, and onto the other side of the film. It's a heavy duty masking tape like the stuff that is used to tape 120 film onto the backing paper.

Just use good tape and don't worry about what is "professional."

I found what I meant but its too expensive around to 2€-3€ and not very available macodirect.de only have around 250 units in stock. It was made by AP.

Didn't or doesn't Kodak use tape for sticking film to spools? So if a professional manufacturer feels that tape is safe then might it not be so?

I feel sure I have looked inside a Kodak cassette only a few years ago and found the end of the film taped to the spool

I've used decent quality masking tape for the last 5 decades.
There are some tips about using it well, but it does the job really effectively.
The real issue being the lack of good quality new, re-usable cassettes - whether in plastic or metal.

All the manufacturers that I've bought film from used tape. Using something else is a recipe for disaster.

I use cassettes left from Kodak factory loads. After exposing, I leave the film tongue out. When it comes time to develop the roll I trim the togue, hook it to the reel and then, in the dark, spool it on to the reel. After spooling I cut the film so that 3/4"/2cm is still sticking out of the cassette. When bulk loading, I tape the new film to the sticking out remnant of film and then wind it on. I use plain-old Scotch tape. Yeah, this method raises the specter of dirt in the felt light trap but I have never had a problem - cleanliness next Godliness and all that (seems to also hold for Devilishness).

TTBOMK Kodak still uses tape to hold the film to the spool. It is a blue, rather sticky, paper tape.

Yet ANOTHER use for expired rolls of 35mm film!!!!
