The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10 ˆ¼ 80 mol% of 1,4-cyclohexane dimethanol, 0.1ˆ¼ 50 mol% of a diol compound expressed as HO-(CH 2 ) a -CO-(CH 2 ) b -OH (where a and b are integers in the range 1 - 5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol% based on dicarboxylic acid The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage. |
