The present invention relates to a low-temperature polyester heat-shrinkable film and a preparation method thereof, belonging to the technical field of heat-shrinkable polyester films. The low-temperature polyester heat-shrinkable film uses modified polyethylene terephthalate as a raw material and can include a single-layer structure, a two-layer structure, a three-layer structure, or other multi-layer structures. When the low-temperature polyester heat-shrinkable film has a structure with more than two layers, the low-temperature polyester heat-shrinkable film can be divided into a polyester core layer and a polyester surface layer. The thickness of the low-temperature polyester heat-shrinkable film is 20-120 μm, and the thickness of the polyester surface layer is 5-20% of the total thickness. The polyester heat-shrinkable film has a high shrinkage rate in the low-temperature zone, a high shrinkage rate in the high-temperature zone, and a high elongation at break. It is particularly suitable for application fields where low temperatures (70-80°C) are used for shrink packaging during the heat shrinkage process, and meets the requirements for the development of green products.
