Heat shrinkable polyester film and heat shrinkable label

The invention claims a hot contractility is polyester film, a plurality of the PET bottle circulating raw material, can with the manufacturing, and a producing high speed. The contractility is polyester film, is more than 2) is multi-layer, comprising more than 1 a layer of PET bottle circulating raw material, comprising 10cm×10cm the square cutting system sample from the film, and installed on 95℃ lukewarm water the sample 10 seconds, a fishing, then installed 10 seconds when 25℃ water, fishing maximum contracting direction thermal shrinkage more than 40%.
