Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a polyester shrink label excellent in all of characteristics of shrink finish, transparency, blocking resistance and heat resistance. SOLUTION: The base film of a polyester shrink label is constituted of (A) a center layer 4 comprising a mixture of copolyester (a) wherein a dicarboxylic acid component is mainly composed of terephthalic acid and a diol component consists of ethylene glycol(EG) and 1,4-cyclohexanedimethanol and an EG/1,4- cyclohexanedimethanol molar ratio is 60/40-80/20 and copolyester (b) wherein a dicarboxylic acid component is mainly composed of terephthalic acid and a diol component consists of EG and diethylene glycol(DEG) and an EG/DEG molar ratio is 50/50-90/10 and (B) the surface layers 5 laminated on both surfaces of the center layer 4 and consisting of the copolyester (a) and inorg. or org. fine particles (c).
