The present disclosure provides a process. In an embodiment, the process includes elongating a multilayer film to a impart a haze value greater than 30% to the multilayer film. The multilayer film has at least two layers: (A) a core layer composed of an ethylene/α-olefin multi-block copolymer and (B) a first skin layer in contact with the core layer, the skin layer composed of an ethylene-based polymer. The process includes releasing the elongating force from the elongated multilayer film to form a hazed multilayer film having a haze value greater than 30%. The process includes stretching the hazed multilayer film to form a stretched multilayer film having a clarity value greater than 80%. The process includes relaxing the stretch force from the stretched multilayer film to form a relaxed multilayer film having a haze value greater than 30%.
