Title (EN) RELEASE FILM FOR PRODUCING CERAMIC GREEN SHEET
(FR) PELLICULE DÉTACHABLE POUR LA PRODUCTION D’UNE FEUILLE DE CÉRAMIQUE CRUE
(JA) セラミックグリーンシート製造用離型フィルム
Abstract:
(EN) [Problem] To provide an excellent release film for producing a ceramic green sheet, the release film being capable of attaining both satisfactorily suitability for winding and prevention of pinholes, local thickness unevenness, etc., even when forming a ceramic green sheet having a reduced thickness. [Solution] A release film for producing a ceramic green sheet, the release film comprising a substrate that is a polyester film containing substantially no particles, a release coating layer formed on one surface of the substrate, and an easy-to-slip coating layer formed on the other surface and containing particles, wherein the easy-to-slip coating layer has an average surface region roughness (Sa) of 1-25 nm, a maximum projection height (P) of 60-500 nm, and an average roughness-curve-element length (RSm) of 10 µm or less.
(FR) [Problème] Fournir une pellicule de libération excellente pour la production d’une feuille de céramique crue, la pellicule de libération étant capable d'atteindre à la fois une aptitude satisfaisante à l'enroulement et la prévention des piquetages, l'irrégularité d'épaisseur locale, etc. même lors de la formation d'une feuille de céramique crue ayant une épaisseur réduite. [Solution] Une pellicule de libération pour la production d’une feuille de céramique crue, la pellicule de libération comprenant un substrat qui est une pellicule de polyester sensiblement exempte de particules, une couche de revêtement de démoulage formée sur une surface du substrat, et une couche de revêtement de glissage facile formée sur l'autre surface et contenant des particules, où la couche de revêtement de glissage facile présente une rugosité de région de surface moyenne (Sa) de 1 à 25 nm, une hauteur de projection maximale (P) de 60 à 500 nm, et une longueur moyenne des éléments de courbe de rugosité (RSm) de 10 µm ou moins.
(JA) 【課題】セラミックグリーンシートを薄膜化させた場合でも、良好な巻取り性と、ピンホールや部分的な厚みばらつき等の防止を両立させることができる優れたセラミックグリーンシート製造用離型フィルムを提供すること。 【解決手段】粒子を実質的に含有していないポリエステルフィルムを基材とし、前記基材の一方の表面上に離型塗布層を有し、かつ、もう一方の表面上に粒子を含有する易滑塗布層を有し、易滑塗布層の領域表面平均粗さ(Sa)が1nm以上25nm以下、最大突起高さ(P)が60nm以上500nm以下、かつ粗さ曲線要素の平均長さ(RSm)が10μm以下であるセラミックグリーンシート製造用離型フィルム。
