Document Type and Number:
WIPO Patent Application WO/2017/086441
Kind Code:
A1
Abstract:
Provided are a film-wound body capable of achieving good temporary adhesion, and a method for producing the film-wound body. The film-wound body is provided with: an adhesive film (2) having a first surface (recessed surface) which is formed such that the thickness of both width-direction ends thereof in the length direction is larger than the thickness at the center portion, and a second surface (flat surface) which is flat and is formed on the opposite side of the first surface; a release film (3) having a heavy-release surface which requires a relatively large release force, and a light-release surface which requires a relatively small release force; and a reel (4) having a core around which the adhesive film and the release film are wound, wherein the adhesive film (2) and the release film (3) are wound so that the first surface of the adhesive film (2) is in contact with the heavy-release surface of the release film (3), and the second surface of the adhesive film (2) is in contact with the light-release surface of the release film (3).
