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˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜30 mol % of a cyclohexane dimethanol compound expressed as HOH2C—[C6H12]m—[C6H12]—CH2OH (where m is an integer from 1˜10), and ethylene glycol as the remainder so that the sum of the entire diol composition may be 100 mol % based on an aromatic dicarboxylic acid. The copolymer polyester of the present invention enables superior products to be provided that reduce cycle time and enhance product processability during mold processing using a heat-shrinking label by complementing low temperature shrinkage properties that may be exhibited by the polyester resin of the prior art copolymerized with 1,4-cyclohexane dimethanol.
A copolymer resin useful for a heat-shrinking film, which contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜30 mol % of a cyclohexane dimethanol based compound represented by Formula 1 below, and ethylene glycol as a remainder so that a sum of the entire diol composition is 100 mol % based on an aromatic dicarboxylic acid:
