Title: COATING FILM ROLL BODY
Abstract:
A coating film roll body (2) is provided with a film roll (2’) and a heat-insulating member (2P). The film roll (2’) is a wound body in which an elongated optical film (10) comprising a thermoplastic resin is wound around a winding core (2a). The heat-insulating members (2P) have heat-insulating properties and cover a part of the film roll (2’). The optical film (10) has concavo-convex embossed parts (11) in one or more locations in the width direction along the winding core (2a). The heat-insulating member (2P) is provided so as to cover: the side surface parts (2c) facing each other in the width direction of the film roll (2’), the outer peripheral surface (2b1) of the film roll (2’) interposed therebetween; and the embossed parts (11) of the optical film (10).
