| 摘要 |
<p>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./2.16 kg) 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, 5 g/10 min. The invention also provides for articles prepared from the inventive films and for methods of making the same.</p> |
