Title (EN) POLYESTER FILM, LAMINATE, AND METHOD FOR PRODUCING POLYESTER FILM
(FR) FILM DE POLYESTER, STRATIFIÉ ET PROCÉDÉ POUR LA PRODUCTION DE FILM DE POLYESTER
(JA) ポリエステルフィルム、積層体およびポリエステルフィルムの製造方法
Abstract:
(EN) A polyester film characterized in that the difference between the maximum value and minimum value of stresses at 5% elongation in each of four directions, taking an arbitrary direction on the film surface as 0°and 45°, 90°, and 135°clockwise to that direction, is 50 MPa or less, the difference between the maximum value and minimum value of the stresses at 15% elongation in each of the four directions is 70 MPa or less, and the elastic modulus in the four directions is within a range of 2.0-3.5 MPa in any direction.
(FR) L'invention concerne un film de polyester caractérisé en ce que la différence entre la valeur maximale et la valeur minimale de contraintes à un allongement de 5 % dans chacune de quatre directions, si on prend une direction arbitraire sur la surface du film comme étant de 0° et des directions de 45°, 90° et 135° dans le sens des aiguilles d'une montre par rapport à cette direction, est inférieure ou égale à 50 MPa, la différence entre la valeur maximale et la valeur minimale des contraintes à un allongement de 15 % dans chacune des quatre directions est inférieure ou égale à 70 MPa et le module d'élasticité dans les quatre directions est dans une plage de 2,0 à 3,5 MPa dans n'importe quelle direction.
(JA) フィルム面における任意の方向を0°とし、その方向に対して時計回りに45°、90°、135°の4方向のそれぞれにおける5%伸長時の応力について、これらの応力の最大値と最小値の差が50MPa以下であり、前記4方向のそれぞれにおける15%伸長時の応力について、これらの応力の最大値と最小値の差が70MPa以下であり、前記4方向における弾性率が、いずれの方向についても2.0~3.5MPaの範囲内にあることを特徴とするポリエステルフィルム。
