6. A multilayer film comprising:
(A) a core layer consisting of an ethylene/α-olefin multi-block copolymer consisting of (i) ethylene and (ii) a C4-C8 α-olefin comonomer, and having a density from 0.865 g/cc to 0.880 g/cc;
(B) a first skin layer in direct contact with the core layer;
(C) a second skin layer in direct contact with the core layer;
the multilayer film is a mono-axially oriented hazed multilayer film and has a haze value greater the 30%, the hazed multilayer film has a layer volume ratio of skin layer (C)-core layer (A)-to-skin layer (B) from 1:4:1 to 1:8:1; and
the hazed multilayer film exhibits a clarity value greater than 80% when subjected to a stretching force from at least 150% elongation to less than or equal to 300% elongation, the hazed multilayer film further exhibiting a haze value greater than 30% when the stretching force is removed,
the haze measured in accordance with ASTM D1003 and the clarity measured in accordance with ASTM D 1746-15.
