In literature, mostly used technique is polyethylene film covering on one side and silicone release paper on the other side. However, I could not find any reason of that usage. Is only one sided separation leads a problem?

Thank you for your reply. But I would like to learn something else. Is a prepreg roll,which has release liners on each two side, show different characteristic (such as strenght, tackness etc.) from a prepreg roll has a release liner only one side? Moreover, what should be those release liners? Polyethylene films or silicone release papers? Where can I learn their effects on the structural characteristic? Edited 5 Years Ago by casci
