摘要：The invention provides a film comprising at least three layers, and wherein atleast one layer is a inner layer with a thickness of 20 percent or less of the total thicknessof the film, and wherein said inner layer, or a polymer component used to form said innerlayer has one of the following properties: A) a MD tensile, 2 percent secant modulus atleast two times higher than the MD tensile, 2 percent secant modulus of a skin layer, orB) a MD tensile, 2 percent secant modulus at least five times lower than the MD tensile, 2percent secant modulus of a skin layer, and where the inner layer, or at least onepolymer component of the inner layer, has one of the following properties: C) a meltindex, 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 forarticles prepared from the inventive films and for methods of making the same.
