Burn-Off / Metalized / Release Liner
Commonly referred to as "burn-off" film and is used primarily in the commercial roofing industry with modified bitumen APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene) membranes. These films can be made from either thin gauge polypropylene or polyethylene material and used to prevent "blocking" of the rolls.
Ultimately the film, as the name suggests, is burned off with a flame torch and melts, allowing the modified bitumen membrane to adhere to itself in a process known as heat welding.
