摘要:
A copolymerized polyester heat shrinkable film which can be used as a label, a cap seal or a direct packaging for various containers is disclosed. The copolymerized polyester heat shrinkable film is made of a copolymerized polyester resin having alternating structures of acid moieties which are derived from acid components and diol moieties which are derived from diol components, the acid components comprising terephthalic acid, and the diol components comprising isosorbide 1,4-cyclohexanedimethanol and ethylene glycol. The copolymerized polyester heat shrinkable film has a shrinkage initiation temperature of equal to or more than 60° C., and a maximum heat shrinkage ratio of less than 2% at 60 to 70° C., and a maximum heat shrinkage ratio of 50 to 90% at 90 to 100° C.
