Even if PET bottle recycled raw materials are used, the present invention provides a heat-shrinkable polyester film having excellent properties and capable of high speed production.n n n A heat-shrinkable polyester film having a multilayer structure of two or more layers having one or more layers containing a PET bottle recycling material, wherein the sample obtained by cutting the film into a square shape of 10 cm × 10 cm is immersed in warm water at 95 ° C. for 10 seconds. The heat-shrinkable polyester film which is taken out and then immersed for 10 second in 25 degreeC water, and taken out for 40% or more of the heat contraction rate of a maximum shrinkage direction.n n n Heat-shrinkable polyester film, PET bottle, heat shrinkage rate, polyhydric alcohols, polyhydric carboxylic acids, alkaline earth metals, phosphorus, melt resistance, heat shrinkable labels |
