Abstract
A roll and a method for producing a roll which are capable of effectively preventing tunneling are provided. A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer, a substrate layer, an adhesive layer, and a release liner, in this order, in a laminating direction. The process film is formed from at least one member selected from polyethylene terephthalate (PET), polyolefins, and polyvinyl chloride (PVC). The surface coat layer is formed from a fluorine resin. The release liner is formed from polyethylene terephthalate (PET). The core is formed from an acrylonitrile-butadiene-styrene copolymer resin (ABS) or polypropylene (PP).
