摘要:
This invention relates to a film comprising a heterogeneous blend of: 1) from 60 to 99 wt % of one or more semi-crystalline polymers; and 2) from 1 to 40 wt % of one or more semi-amorphous polymers; where the blend has: an MFR of 0.5 to 100 dg/min, a haze of 20% or less, and a permanent set of greater than 65%; and where the film is 2.5 to 635 microns thick and has: a haze of 10% or less, a 1° Secant tensile modulus of 100,000 to 30,000 psi, an Elmendorf tear in the machine direction and transverse direction of 45 g/mil or more, a total energy impact of 3 J or more; and a 45 degree gloss of 82 or more.
