WÄRMESCHRUMPFBARE POLYESTERFOLIE UND WÄRMESCHRUMPFBARES ETIKETT

摘要

[PROBLEMS] To provide a heat-shrinkable polyester film which has excellent characteristics and which can be produced at a high rate, even when a PET bottle-recycled material is used. [MEANS FOR SOLVING PROBLEMS] A heat-shrinkable polyester film having a multi-layer structure of at least two layers, among which at least one layer is a layer containing a PET bottle-recycled material, wherein a heat shrinkage percentage in a maximum shrinkage direction of a 10 cm square sample cut out from the film is 40 % or higher, under the condition that the square sample is immersed in hot water of 95°C for 10 seconds and then immersed in water of 25°C for 10 seconds.
