Title:
セラミックグリーンシート製造用離型フィルム
Document Type and Number:
Japanese Patent JP6852720
Kind Code:
B2
Abstract:
To provide a release film for producing a ceramic green sheet maintaining the high smoothness of the surface of a release layer of a release film, having low peel force even when a peel angle is low upon the production of a ceramic green sheet compared with the conventional release film for producing a ceramic green sheet, and having low peel force upon peeling even in the production of an ultrathin layer ceramic green sheet.SOLUTION: There is provided a release film using a polyester film as a base material, in which at least one side of the base material contains a surface layer A substantially not including inorganic particles, and a release layer is laminated on the surface of the surface layer A in at least one side directly or via the other layer. When ceramic green sheet molding is performed to the surface of the release layer, a peel temperature between the ceramic green sheet and the release film reaches 50°C, and peel force F (T50/A30) at a peel angle of 30° reaches 60 mN/mm or lower.SELECTED DRAWING: Figure 1
