Disclosed herein is an olefin copolymer shrink film comprising an alpha-olefin/aromatic vinyl compound random copolymer. This alpha-olefin/aromatic vinyl compound random copolymer comprises 99.9 to 58 mol % of structural units derived from ethylene, 0 to 30 mol % of structural units derived from an alpha-olefin having 3 to 20 carbon atoms (provided that the total of the structural units derived from ethylene and the structural units derived from an alpha-olefin having 3 to 20 carbon atoms ranges from 99.9 to 88 mol %), and 0.1 to 12 mol % of structural units derived from an aromatic vinyl compound. The alpha-olefin/aromatic vinyl compound random copolymer has an intrinsic viscosity [eta], as measured in decalin at 135° C., of 0.1 to 10 dl/g and has a melting point, as measured by a differential scanning calorimeter, of 60 to 125° C. The olefin copolymer shrink film is oriented in at least one direction. The olefin copolymer shrink film has excellent low-temperature shrinkability and transparency.
