Abstract
A polyethylene-based multi-layer film, which is particularly useful as a greenhouse film, is provided. The multi-layer film contains an ethylene/α-olefin interpolymer composition having a Comonomer Distribution Constant (CDC) in the range of from 75 to 200, a vinyl unsaturation of less than 0.15 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from 2 to 20; a density in the range of from 0.903 to 0.950 g/cm, a melt index (I) in a range of from 0.1 to 5 g/10 minutes, a molecular weight distribution (M/M) in the range of from 1.8 to 3.5.
