Abstract:
An olefin copolymer shrink film comprising an .alpha.-olefin/aromatic vinyl compound random copolymer and a tackifier, said .alpha.-olefin/aromatic vinyl compound random copolymer comprising as polymerized structural units:99.9 to 58 mol % ethylene,0 to 30 mol % .alpha.-olefin having 3 to 20 carbon atoms provided that the total of said ethylene structural units and said .alpha.-olefin structural units of an .alpha.-olefin having 3 to 20 carbon atoms ranges from 99.9 to 88 mol %, and0.1 to 12 mol % aromatic vinyl compound;said .alpha.-olefin/aromatic vinyl compound random copolymer having an intrinsic viscosity (.eta.), as measured in decalin at 135.degree. C., of 0.1 to 10 dl/g and having a melting point, as measured by a differential scanning calorimeter, of 60 to 125.degree. C.,wherein the tackifier is blended in an amount of 1 to 50 parts by weight per 100 parts by weight of the .alpha.-olefin/aromatic vinyl compound random copolymer, andsaid olefin copolymer shrink film being oriented in at least one direction.
