    Abstract: A composition suitable for a film having a 1% secant flexural modulus (MD or TD) of at least 55,000 psi and a dart drop impact of at least 500 g is provided. The composition comprises a broad molecular weight distribution polypropylene with at least 50 mol % propylene and having: a molecular weight distribution (Mw/Mn) greater than 6, a branching index (g?vis) of at least 0.95, and a melt strength of at least 2 cN; and a polyethylene with at least 70 mol % ethylene and having: a density of from 0.910 to 0.923 g/cm3, a melt index (I2) of from 0.1 to 1.2 g/10 min, a melt index ratio (I21/I2) of from 20 to 35, a weight average molecular weight (Mw) of from 150,000 to 400,000 g/mol, and an orthogonal comonomer distribution and/or at least a first peak and at least a second peak in a comonomer distribution analysis.
