    Abstract: The invention provides a film comprising at least three layers, and wherein at least one layer is a inner layer with a thickness of 20 percent or less of the total thickness of the film, and wherein said inner layer, or a polymer component used to form said inner layer has one of the following properties: A) a MD tensile, 2 percent secant modulus at least two times higher than the MD tensile, 2 percent secant modulus of a skin layer, or B) a MD tensile, 2 percent secant modulus at least five times lower than the MD tensile, 2 percent secant modulus of a skin layer, and where the inner layer, or at least one polymer component of the inner layer, has one of the following properties: C) a melt index, I2 (190°C/2.16kg) of less than, or equal to, 2 g/10 min, or D) a melt flow rate, MFR (230°C/2.16 kg) of less than, or equal to, 5g/10 min. The invention also provides for articles prepared from the inventive films and for methods of making the same.

    Abstract translation: 本发明提供一种包含至少三层的薄膜，其中至少一层是厚度为薄膜总厚度的20％或更小的内层，其中所述内层或用于形成的聚合物组分 所述内层具有以下性质之一：A）MD拉伸，2％割线模量比皮革层的MD拉伸，2％正割模数高至少两倍，或B）MD拉伸，2％割线模量 比皮肤层的MD拉伸率，2％正割模数低至少5倍，并且其中内层或内层的至少一种聚合物组分具有以下性质之一：C）熔体指数I2 （190℃/ 2.16kg）小于或等于2g / 10min，或D）熔体流动速率，MFR（230℃/ 2.16kg）小于或等于5g / 10 分钟。 本发明还提供了由本发明的薄膜制备的制品及其制备方法。
