More Information
Summary:The instant invention provides a sealant composition, method of producing the same, film layers and multilayer structures made therefrom. The linear low density polyethylene composition suitable for sealant applications according to the present invention comprises: less than or equal to 100 percent by weight of the units derived from ethylene; less than 35 percent by weight of units derived from one or more [alpha]-olefin comonomers; wherein said linear low density polyethylene composition has a density in the range of 0.900 to 0.920 g/cm3, a molecular weight distribution (Mw/Mn) in the range of 2.5 to 4.5, a melt index (I2) in the range of 0.5 to 3g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of from 2.2 to 3, vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of said composition, and a zero shear viscosity ratio (ZSVR) in the range from 1.0 to 1.2.
