Abstract: In order to ensure that the packing drinking water production process is more environment friendly and safer，technologies of pulsed light sterilization in packaged drinking water bottle cap sterilization were studied. The key impact factors of pulsed light sterilization technology were optimized，the best sterilization conditions of bottle cap were obtained，which impulse kvoltage was 7kv，irradiation distance was 9cm，irradiation interkval was 0.8s，blink twice times. The reproducibility test showed that the condition was stable and could be used in practical production.
