What could I use for fruit leather liners for round food dehydrator trays?

I just bought a second-hand round food dehydrator with clear plastic trays. There isn’t a company name/brand on it, just the model No. KN 128, which I’ve already googled.

Anyhow…I want to make fruit leathers/roll-up-type-things and would like to know what I might use in the absence of those plastic fruit leather trays (which did not come with this purchase).

Recipes for fruit leathers also welcomed.

Thanx!

My mom used to make those all the time growing up. She just took saran wrap and wrapped it around the tray. Make sure it’s not loose because otherwise it can blow over your fruit roll up and keep it from dehydrating.
