Film Adhesive Backing Film

The rolls of film adhesive that I use have only one-backing sheet. This means that everytime I need some, I need to defrost the whole roll, which has its obvious drawbacks.

Im looking for a readily available (ie cheap and probably around the home!) backing film that I could put on the other side so that I can defrost small sheets at a time - any suggestions for materials that wouldnt compromise the resin system?

Would greaseproof paper be appropriate?

thanks

Your supplier generally sells embossed backing material. Usually it’s white. It’s used in conjunction with a ply cutting table.
