膜及其制作方法。
背景技术 离型膜又称防粘膜， 即 l iner,离型膜是以 PET、 B0PP、 PE、 PC, PS、 CPP为基材制 作的一种表面具有低表面能的特性， 与胶带之间的剥离力可调节的产品。 离型膜的特 点是表面平整、 洁净度高， 后续加工尺寸稳定， 透明度及颜色可调整， 薄膜的厚度与 基材的种类可选择的范围广。 可利用离型膜这些特点向光学与电子领域的零部件的深 加工发展， 从而适应这一领域越来越多的自动化生产工艺过程。 离型力的重要性： 离型膜的最终要求是实现在载体膜的物理性能满足要求的前提 下获得稳定的离型力 （在 180度角度下， 以 300mm/min的剥离速度下所检测到的力值） 。 离型膜一般需要与 PSA复合使用。在电子或光学零部件的加工领域需要一些双面胶带作 为粘结件， 双面胶带首先要与离型膜复合， 然后再进行模切成各种形状大小、 最后进 入自动或手工贴装过程。 由于人工成本的增加， 及对过程控制的严格要求， 越来越多 的趋向于机器自动吸附贴装， 即胶带在吸盘吸附下自动从离型膜表面脱离。 这要求离 型膜的离型力足够轻， 同时离型膜的离型面对胶表面特性的影响降到最低。
