一系列双轴取向聚丙烯薄膜的结构表征和各种最终用途的性能进行了广泛的研究。性能和结构特征之间的关系，如结晶度含量和分子取向的结晶相和非结晶相进行了比较，在单轴取向聚丙烯薄膜类似的关系。单轴取向膜和双轴取向膜之间的显著差异，特别是关于非线性机械行为（韧性、冲击强度、撕裂强度）的显著差异可以至少部分地根据与非结晶相相关的结构特征（分子取向和流动性）来解释。
A series of biaxially oriented polypropylene films has been extensively investigated with respect to structural characterization and with regard to various end-use properties. The relationships between properties and structural characteristics such as crystallinity content and molecular orientation in crystalline and non-crystalline phases were compared with similar relationships in uniaxially oriented polypropylene films. Notable differences between uni- and biaxially oriented films, in particular with regard to non-linear mechanical behavior (tenacity, impact strength, tear strength) could be explained, at least partly, in terms of structural characteristics (molecular orientation and mobility) related to the non-crystalline phase.
