Composition and films thereof

A coextruded film comprising:

• (a) at least one layer comprising at least one coupled propylene copolymer, the at least one coupled propylene copolymer having a melt strength of at least 40 cN, a melt flow rate of at least 0.1 g/10 min and less than 2.0 g/10 min;
• and
• (b) at least one layer comprising an in-reactor blend of linear low density polyethylene and a substantially linear polyethylene or a homogeneously branched linear polyethylene, wherein the in-reactor blend of (b) has a melt index of at least 0.1 g/10 min and less than 15 g/10 min.

A coextruded film comprising:

• (a) at least one layer comprising at least one coupled impact propylene copolymer coupled by reaction with a coupling agent and having a melt strength of at least 40 cN;
• and
• (b) at least one layer comprising an in-reactor blend having a melt index of at least 0.3 g/10 min and less than 10 g/10 min and having a density of at least 0.88 g/cc and less than 0.930 g/cc, the in-reactor blend comprised of a linear low density polyethylene and a substantially linear polyethylene or a homogeneously branched linear polyethylene, wherein the film exhibits a mechanical properties balance.
