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/&#x3b1;-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%.

Multilayer film with reversible haze

The invention provides a composition comprising the following:

Ethylene-based polymer compositions and foams

The invention provides a composition comprising the following: A) a first polymer selected from the following: i) an ethylene/&#x3b1;-olefin interpolymer; or ii) an ethylene/&#x3b1;-olefin multi-block interpolymer; B) a second polymer selected from the following: iii) an ethylene/&#x3b1;-olefin interpolymer; iv) an ethylene/&#x3b1;-olefin/non-conjugated diene interpolymer; or v) an ethylene/&#x3b1;-olefin multi-block interpolymer; and wherein the first polymer has a density from 0.880 to 0.910 g/cc, and the second polymer has a density less than, or equal to, 0.867 g/cc, and wherein the weight ratio of the first polymer to the second polymer is from 0.5 to 9.
