1. Dual transducers control and bag length can be let and cut in one step . 

2. Interface are easy and quick to set and operate 

3. Failures can be self-diagnosised and displays clearly. 

4. High sensitivity electrical eye traces and sealing position is input numerically for accuracy . 

5. PID control temperature independently which is more suitable for packing different materials. 

6. Positioned stop function without sticking knife and wasting film. 

7. Simple driving system , reliable working, convenient maintenance. 

8. All control is realized through software, easy for function adjusing and technical upgrading .
