Coextruded multilayer blown films are produced comprising: a core layer comprising at least one random polypropylene copolymer; at least one skin or intermediate layer adjacent to said core layer; wherein the coextruded multilayer film has at least 30% higher machine direction tear, at least 30% improved tear ratio (machine direction tear divided by transverse direction tear) and at least 10% lower film haze, relative to a similar multilayer film comprising at least one impact polypropylene copolymer in the core layer. |
