Does anyone know where to find that clear patch to fix holes on kite bladders? I have a sample here that came with an old Best kite that was given to me, it is big, probably half size of a A4 paper, and on the back it says Sekisui #5760. A quick search finds it on aliexpress, but they are all double sided, and I want it to stick to just one side.

When im repairing kites with double sided tape thats wider then a kites panel overlap i will dust the excess width with baby powder so the sewing machines foot doesnt stickand scruntch the canopy whilst sewing.
So if you want it single sided powder it?

Don't use that stuff in the pic its useless for bladder repairs, just use some Tear Aid www.kitepower.com.au/products/tear-aid-1?_pos=1&_psq=Tear+Ai&_ss=e&_v=1.0
The link above is for the 3" wide stuff and we also have the 6" wide.
