Would any colleague know if they know, or even exist, a commercial adhesive tape that I can apply directly to the surface of the coins, and when this tape is removed, it does not leave any adhesive, glue, or other similar product that could damage the coin? ?

There are ‘no residue’ tapes but why gamble put it in a small LDPE bag and tap that this also provides a little extra protection.
I had some coin send to me with similar tape. It didn't leave any residue and it was very easy to remove but because of that it also didn't stick very well so if the parcel will be handled a bit rough I could imagine that coins will rattle around in it after a while.
I understand and thank you, but I would like to try to reduce the time in preparing the package for shipping, packaging each coin one by one, it takes a lot of time, of course to make good packaging. There was a store in Brazil that sold coins, which they wrapped with a heat-shrinkable film, I believe, the coins were in very tight pockets, it looked like a coin holder sheet, but really tight. But this store closed, which I believe is the best solution. Thank you for all the answers and help, sorry for bad English.
Please keep in mind a tape that does not leave residues, when exposed to higher or lower temperatures, or different degrees of humidity may change its characteristics, and leave residue.
Post bags are exposed to those variations; some countries may take care of the weather changes, but other don't.
My solution was to buy a plastic bag sealer, and when packaging, I prepare the bag making seals along it, so it will have long pockets, Iput a coin on each, then seal crossing, and repeat till all coins are packed. Coins will never be in contact; if I want them to be tight, I can place 2 cardboard sheets, one on each side, and fix with tape on edges. I use polyurethane foam sheets instead, is lighter and more rigid than cardboard. Sheets of 2 to 3 mm (1/16" to 1/8") work fine.

If your friend could make a video to watch in practice, I think it would be interesting for everyone else, if it doesn't require too much work obviously!
I have found through trial and error that every type of adhesive tapes available in the UK I have used leaves some residue, the best way to remove the residue is a dip in an acetone bath

I prefer to use isopropyl alcohol, that does not affect the patina in coins.

But alcohol contains a certain amount of water, will it not oxidize over time? Does anyone have any other suggestions for easily making swap packaging?
I received here in Brazil, a swap from Latvia, using paper adhesive tape, which practically had zero adhesive, little residue was cleaned using a dry flannel, very easy. I don't know what this tape would be in Brazil, nor do I know if I could buy it here, but in my opinion it was very good.

Isopropyl alcohol does not contain water, if is pure, this is why is used to clean old photography items.

Just wrap them on toilet paper, then tape them to the cardboard.
