摘要： A multilayer blown film having an inner layer, a first outer layer, and a second outer layer, wherein the inner layer comprises an ethylene-based polymer having a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2≥7.0−1.2×log (I2); and the first outer layer and the second outer layer independently comprise a polyethylene composition which comprises the reaction product of ethylene and, optionally, one or more alpha olefin comonomers, wherein the polyethylene composition is characterized by the following properties: (a) a melt index, I2, of from 0.1 to 2.0 g/10 min; (b) a density of from 0.910 to 0.930 g/cc; (c) a melt flow ratio, I10/I2, of from 6.0 to 7.6; and (d) a molecular weight distribution, (Mw/Mn) of from 2.5 to 4.0.

摘要： Embodiments are directed to compositions comprising at least one polyethylene (PE) having a density ranging from 0.850 g/cc to 0.970 g/cc, and a polymer processing aid (PPA) masterbatch comprising a PPA polymer blend, at least one polymeric carrier, and optionally up to 12 wt. % of one or more inorganic materials. The PPA polymer blend comprises from 40 to 60 wt. % of one or more fluoroelastomers, and from 40 to 60 wt. % of polyethylene glycol. The composition further comprises at least one fragrance oil. The composition is defined by the equation: RED (PE−PPA masterbatch)
