Zusammenfassung:	The utility model discloses a system for preparing a polyester film for a low-fog high-permeability release film. The system comprises a first mixing bin, a second mixing bin and a third mixing bin, the output end of the first mixing bin is respectively connected with the second mixing bin and the third mixing bin; the output end of the second mixing bin is respectively connected with the first double-screw extruder and the third double-screw extruder; the output end of the third mixing bin is connected with a second double-screw extruder; the output ends of the first double-screw extruder, the second double-screw extruder and the third double-screw extruder respectively and correspondingly extrude thick sheets corresponding to the upper surface layer, the core layer and the lower surface layer, and the thick sheets are input into a film drawing mechanism to prepare the polyester film for the low-fog high-permeability release film. According to the polyester film for the low-fog high-transmittance release fil
