Abstract: An extended film and a manufacturing method thereof are provided. The extended film includes a poly(lactic acid) and a block copolymer, wherein the block polymer includes a first block, a second block and a third block that connected with each other by chemical bonds. The extended film is formed by steps of mixing poly(lactic acid) and the block copolymer to form a mixture, compressing the mixture to form a board body and extending the board body to form an extended film, thereby forming an extended film having properties of high thermal-resistance and high transparency, the film thus obtained is applicable for packaging use.

Abstract translation: 提供了一种延伸膜及其制造方法。 延伸膜包括聚（乳酸）和嵌段共聚物，其中嵌段聚合物包括通过化学键彼此连接的第一嵌段，第二嵌段和第三嵌段。 延伸膜通过混合聚（乳酸）和嵌段共聚物以形成混合物的步骤形成，压缩混合物以形成板体并延伸板体以形成延伸膜，由此形成延伸膜，其具有 高耐热性和高透明性，因此得到的膜适用于包装用途。
