Abstract: PURPOSE: A biaxially oriented polyester film and a manufacturing method thereof are provided to prevent the tearing of the film when manufacturing an in-mold by controlling the ratio of the intensity and the elongation. CONSTITUTION: A biaxially oriented polyester film comprises the following: an anti-static layer(10) formed on one side of a polyester base film(20); and a bonding layer(30) formed on the other side of the polyester base film. The polyester film extends 2~4 times to the film progressive direction at 60~130 deg C. The polyester film extends 2~4 times to the film width direction at 60~140 deg C.

Abstract translation: 目的：提供双轴取向聚酯膜及其制造方法，以通过控制强度和伸长率的比例来防止在制造模内时膜的撕裂。 构成：双轴取向聚酯薄膜包括：在聚酯基薄膜（20）一侧形成的防静电层（10）; 和形成在聚酯基膜的另一侧上的接合层（30）。 聚酯薄膜在60〜130℃下向膜进行方向延伸2〜4倍。聚酯薄膜在60〜140℃下向薄膜宽度方向延伸2〜4倍。
