Title
(EN) FILM, FILM ROLL AND METHOD FOR PRODUCING FILM
(FR) FILM, ROULEAU DE FILM ET PROCÉDÉ DE PRODUCTION DE FILM
(JA) フィルム、フィルムロールおよびフィルムの製造方法
Abstract
(EN) [Problem] To provide: a film which is capable of suppressing the occurrence of winding failure; a film roll; and a method for producing a film. [Solution] The present invention is a film which is provided with: a first end part and a second end part in the width direction that intersects with the longitudinal direction; a central part that is positioned between the first end part and the second end part; a projected point wherein, among the first end part and the second end part, at least the thickness Te1 of the first end part is smaller than the thickness Tc of the central part; and a recessed point wherein the thickness Te1 of the first end part is larger than the thickness Tc of the central part, said recessed point being arranged at a position that is different from the position of the projected point in the longitudinal direction.
(FR) Le problème décrit par la présente invention est de fournir : un film qui est capable de supprimer l’apparition de défaillance d’enroulement ; un rouleau de film ; et un procédé de production d’un film. La solution selon l’invention porte sur un film pourvu : d’une première partie d’extrémité et d’une seconde partie d’extrémité dans le sens de la largeur qui entre en intersection avec le sens longitudinal ; une partie centrale qui est positionnée entre la première partie d’extrémité et la seconde partie d’extrémité ; un point en saillie, parmi la première partie d’extrémité et la seconde partie d’extrémité, au moins l’épaisseur (Te1) de la première partie d’extrémité étant inférieure à l’épaisseur (Tc) de la partie centrale ; et un point renfoncé dans lequel l’épaisseur (Te1) de la première partie d’extrémité est plus grande que l’épaisseur (Tc) de la partie centrale, ledit point renfoncé étant disposé à une position qui est différente de la position du point projeté dans le sens longitudinal.
(JA) 【課題】巻取り不良の発生を抑えることが可能なフィルム、フィルムロールおよびフィルムの製造方法を提供する。 【解決手段】本発明は、長手方向に交差する幅手方向の第1端部および第2端部と、前記第1端部および前記第2端部の間の中央部と、前記第1端部および前記第2端部のうちの少なくとも前記第1端部の厚みTe1が前記中央部の厚みTcよりも小さい、凸状位置と、前記長手方向において前記凸状位置とは異なる位置に配置されるとともに、前記第1端部の厚みTe1が前記中央部の厚みTcよりも大きい、凹状位置とを備える、フィルム。
