MULTI-LAYERED SHRINK FILMS |
摘要 |
<p>A multi-layered shrink film comprising: at least three layers including two skin layers and at least one core layer; wherein at least one layer comprises from 10 to 100 weight percent units derived from one or more ethylene-based polymer compositions characterized by having Comonomer Distribution Constant in the range of from 75 to 220, a vinyl unsaturation of from 30 to 100 vinyls per one million carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from at least 2.5 to 15; a density in the range of 0.924 to 0.940 g/cm3, a melt index (I2) in the range of from 0.1 to 1 g/10 minutes, a molecular weight distribution (Mw/Mn) in the range of from 2.5 to 10, and a molecular weight distribution (Mz/Mw) in the range of from 1.5 to 4; and wherein the multi-layered film exhibits at least one characteristic selected from the group consisting of 45 degree gloss of at least 50%, a total haze of 15% or less, an internal haze of 8% or less, 1% CD Secant Modulus of 43,000 psi or greater, 1% MD Secant Modulus of 38,000 psi or greater, CD shrink tension of at least 0.7 psi, and/or MD shrink tension of at least 10 psi.</p> |
