SHRINKABLE FILM MADE OF OLEFINIC COPOLYMER

摘要

PROBLEM TO BE SOLVED: To obtain a shrinkable film excellent in low-temperature shrinkability and transparency. SOLUTION: This shrinkable film comprises anα-olefin-aromatic vinyl compound random copolymer composed of 99.9-58 mol% constituent units derived from ethylene, 0-30 mol% constituent units derived from a 3-20Cα-olefin (with the proviso that the total amount of both is 99.9-88 mol%) and 0.1-12 mol% constituent units derived from an aromatic vinyl compound, has an intrinsic viscosity [η] measured at 135 deg.C in decalin within the range of 0.1-10 dL/g and further the melting point measured by a differential scanning type calorimeter within the range of 60-125 deg.C and is oriented in at least one direction.
