hi Pengyou, I've made it on parchment paper. It only sticks slightly which isn't a problem if it is dry enough. I usually cut the paper with the fruit leather with a scissors, in long strips, then roll each strip of fruit leather with the paper, into a kind of fruit roll up.
I have found that not every fruit on its own will make good pliable fruit leather. It needs to have some pectin in it, so I often make fruit leather with a fruit plus either apple or pear mixed in for texture and sweetness.
Good luck.
