1. Two layers of film feeding, pull film automatically,automatic welding both sides, automatic tear up waste edge  , automatic cutting, high production efficiency, servo motor control, location precision.
2. Strong output power,frequency generated by the 27.12 MHZ and 40.68 MHZ, conform to the international industry standard, all kinds of special electronic circuit control device, can avoid improper operation, can fast working  and keep the quality good .
3. Independent research and development of the latest generation of electronic spark protection device, when the spark generated automatically it can cut off the high frequency circuit in the shortest time,protect the mould, reduce damage parts and object, when the current is too high, automatic cut off the high pressure to protect oscillation tubes and rectifier.
4. PLC programming control, touch screen interface, easilly operation.Parameters such as welding time, holding time can be set by the touch screen easily, and all parameters and production can be set and adjust within the screen, when production to achieve automatic warning, convenient for user counting.
5. Program with password protection, parameter preset function, can choose according to the different thickness of PVC material corresponding parameters without item by item, from change the parameters, the user can according to the product make different length of bags.
6. This machine automatically welding two sides and cutting then manual put the heating film,discharge the air automatically.
