Precision for Enhanced Sealing Performance
Hot-melt glue is completely heated with hot air and is firmly pressed between press rolls to totally seal the bag. For inner PE layer bags,the PE film is first sealed to eliminate moisture and dust entry and prevent degeneration of the products.
Adjustable Heater Temperature
The temperature of both hot air heater and inner layer heater is easily adjustable to suit bag specifications and conditions. Enhanced efficiency and quality packaging are realized at all times.
Ease of Maintenance
Major parts are protected by sealed covers to substantially reduce machine problems. The machine rejects dirt,and maintenance and control of the machine is quite easy.
