A monoaxially oriented films and methods of making films including a heat sealable layer including propylene homo-polymer or copolymer and 3-15wt% of at least one elastomer. The oriented films have a refractive index that satisfies the condition 5≤delta n = | n (MD) - n (TD) | x 1000 ≤ 25, in which n (MD) is a refractive index of the film in a machine direction, and n (TD) is a refractive index of the film in a transverse direction. The films are suitable for pouch applications requiring an "easy-tear" linear tear feature and excellent hermetic seal properties, particularly for retort pouches |
