Abstract：Regarding the demand of heat-seal system bag，combining PLC of numerical control design, this paper emphatically analyses base on auxiliary relay of state sign technique, present a suit of MPU program, under the 1 e different environment, set down reasonable heat-seal temperature, the pressure and temporal fluctuate. Finally, experimental movement situation is good. enhanced the heat-seal working efficiency and the intensity greatly .
