SHRINKABLE FILM MADE FROM OLEFIN COPOLYMER

摘要

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 Ä eta Ü, as measured in decalin at 135 DEG C, of 0.1 to 10 dl/g and has a melting point, as measured by a differential scanning calorimeter, of 60 to 125 DEG 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.
