Filed: 2009-10-02
Abstract: The purpose of the present invention is to have a cover film in the direction of width stick without position error when forming a cover film on a material layer of a long shape substrate, so as to increase the position accuracy. Comparing to the coefficient of elasticity of glass transition point of flexible polyolefin class (5b) belonged to the middle layer of a release film (5), the coefficient of elasticity of adhesive (3a) for sticking the cover film (2) is at least fifty times and more. Therefore, a base film (1), the adhesive (3a), the cover film (2) and the release film (5) are laminated in order, the flexible polyolefin class (5b) discharges toward to the arrow direction of the figure, and a thermal endurance film (5c) of the lower layer of the release film (5) also extends toward to the arrow direction of the figure. Accordingly, the cover film (2) extends toward to the arrow direction. At this time, although the adhesive (3a) starts to soften, the slide of the cover film (2) is restrained because the coefficient of elasticity of the adhesive (3a) is much higher than that of the flexible polyolefin class (5b). The position error of width direction for the cover film then is not occurred.
