Abstract: Provided is a method for removing a coating film from a coated film including a coating film containing a water-soluble resin on at least one side of a base film. The method includes: supplying a cleaning liquid in a form of droplets to a surface of the coating film, and retaining the cleaning liquid in the form of droplets on the surface of the coating film; and subsequently removing the coating film containing the cleaning liquid from the coated film.

Abstract: A die, having multiple discharge orifices arrayed in a generally straight line for applying an application fluid to an object of application, and an internal application fluid reservoir, wherein braces are provided in the application fluid reservoir and extending in a direction generally orthogonal to the direction of the array of the discharge orifices. Also, an application apparatus and method for application fluid, for relatively moving a base material wherein stripe-shaped vertical barrier ribs are formed on the surface of the base material and horizontal barrier ribs having a height equal to or lower than the vertical barrier ribs are formed in a direction generally orthogonal to the vertical barrier ribs, and a die provided facing the base material, while discharging application fluid from multiple discharge orifices provided on the die, thereby applying application fluid to selected grooves between the vertical barrier ribs of the base material.
