Disclosed herein is a heat-shrinkable co-polyester film having terephthalic acid and ethylene glycol as main components and containing 1,4-cyclohexanedimethanol at the amount of 3&#x2013;40 mol %. The heat-shrinkable co-polyester film has a crystallization temperature of 80&#x2013;220&#xb0; C., a heat shrinkage (%) higher than 30% in at least one direction of longitudinal and transverse directions in 90&#xb0; C. hot water, and a maximum shrinkage stress lower than 3 kg/mm. The film is suitable for use as various wrapping materials, such as covering, binding and casing materials. Particularly, the film is used to cover a cap, body and shoulder, etc. of various vessels and rod-shaped molded articles and thus to provide labeling, protection, binding or an improvement in product value. Also, the film can be used for multi-package.

Heat-shrinkable polyester film having excellent crystallinity

Disclosed herein is a heat-shrinkable co-polyester film containing terephthalic acid or dimethyl terephthalate as a dicarbonic acid component, and ethylene glycol, neopentyl glycol and propylene glycol as diol components, in which the co-polyester film has a crystallization temperature of 80&#x2013;220&#xb0; C., and a heat shrinkage (%) higher than 30% in at least one direction of longitudinal and transverse directions in 90&#xb0; C. hot water. This film is suitable for use as various wrapping materials, such as covering, binding and casing materials.
