PET film needs to go through two key temperature points from solid to molten liquid at room temperature, namely glass temperature and melting temperature. The glass temperature of the PET film is about 67°C, when the polyester changes from a highly elastic state to a glass state. The melting temperature of the polyester is about 267°C, at which time the polyester changes from a solid state to a molten state. Because the polyester is a semi-crystalline polymer, the polyester has a crystallization temperature of about 160°C. At this time, due to the heating of the polyester, the interaction between the molecular chains is increased, and the molecular chains are rearranged under the interaction to form a ball. Crystal, polyester cannot be crystallized completely, and its maximum crystallinity is 55%. In addition, according to the online understanding of the coating, some important physical properties of polyester are: the heat distortion temperature (1.8MPa) is about 224°C, and the temperature at the maximum crystallization rate is about 190°C.
