双向拉伸聚酯薄膜(简称BOPET)，是(shi)利用有光(guang)料(也(ye)称大有光(guang)料，即(ji)是(shi)在原材料聚酯切片(pian)中(zhong)不添加(jia)钛白(bai)粉，经过干燥、熔融、挤出、铸(zhu)片(pian)和(he)纵(zong)横(heng)拉伸的(de)(de)高(gao)档薄(bo)膜，用途广泛。BOPET薄(bo)膜具(ju)有强度高(gao)、刚性(xing)(xing)(xing)(xing)(xing)(xing)(xing)好(hao)、透明(ming)、光(guang)泽度高(gao)等特 点;无(wu)嗅、无(wu)味、无(wu)色、无(wu)毒、突出的(de)(de)强韧性(xing)(xing)(xing)(xing)(xing)(xing)(xing);其(qi)拉伸强度是(shi)PC膜、尼龙膜的(de)(de)3倍，冲击强度是(shi)BO PP膜的(de)(de)3-5倍，有极(ji)好(hao)的(de)(de)耐磨性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐折叠性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐针孔性(xing)(xing)(xing)(xing)(xing)(xing)(xing)和(he)抗撕裂性(xing)(xing)(xing)(xing)(xing)(xing)(xing)等;热(re)收缩性(xi🍒ng)(xing)(xing)(xing)(xing)(xing)(xing)极(ji)小(xiao)，处(chu)于120°C下，15分(fen)钟后仅(jin)收缩1.25%;具(ju)有良(liang)(liang)好(hao)的(de)(de)抗静电性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，易进行(xing)真空镀(du)铝，可以涂布(bu)PVDC，从(cong)而(er)提高(gao)其(qi)热(re)封性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、阻隔性(xing)(xing)(xing)(xing)(xing)(xing)(xing)和(he)印刷的(de)(de)附着力;BOPET还具(ju)有良(liang)(liang)好(hao)的(de)(de)耐热(re)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、优异的(de)(de)耐蒸煮(zhu)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐低温(wen)冷冻性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，良(liang)(liang)好(hao)的(de)(🎶de)耐油性(xing)(xing)(xing)(xing)(xing)(xing)(xing)和(he)耐化学(xue)品性(xing)(xing)(xing)(xing)(xing)(xing)(xing)等。
BOPET薄膜除了硝基苯、氯仿、苯甲醇外，大多数化学品都不能使它溶解。不过，BOPET会受到强碱的侵蚀，使用时应注意。BOPET膜吸水率低，耐水性好，适(shi)宜包装(zhuang)含水量高的食(shi)品。
