Title:
SHRINKABLE FILM MADE FROM OLEFIN COPOLYMER
Document Type and Number:
WIPO Patent Application WO/1998/032786
Kind Code:
A1
Abstract:
A shrinkable film characterized by being made from an $g(a)-olefin/vinyl aromatic random copolymer which comprises 99.9 to 58 mole % of structural units derived from ethylene and 0 to 30 mole % of structural units derived from a C�3?-C�20? $g(a)-olefin (with the sum total of both being 99.9 to 88 mole %) and 0.1 to 12 mole % of structural units derived from an aromatic vinyl compound and which exhibits an intrinsic viscosity [$g(h)] of 0.1 to 10 dl/g as determined at 135 �C in decalin and a melting point of 60 to 125 �C as determined with a differential scanning colorimeter, and by being oriented in at least one direction. The film is excellent in low-temperature shrinkage and transparency.
