Abstract

See full text

A heat-shrinkable polyester film made of a polyester-forming resin composition includes a recycled material, and has an exothermic crystallization peak and an endothermic melting peak which are determined via differential scanning calorimetry, and which satisfy relationships of T2−T1≤68° C. and T3−T2≤78° C., where T1 represents an onset point of the exothermic crystallization peak, T2 represents an end point of the exothermic crystallization peak and an onset point of the endothermic melting peak, and T3 represents an end point of the endothermic melting peak. A method for manufacturing the heat-shrinkable polyester film is also disclosed.
