Multi-functional in one device:
1. Integrated functions of automatic paper feeding, cutting, sealing and printing.
2. Can be used independently for cutting, sealing and printing functions. 
Cutting function:
1. The cutting margin for the sealing edge can be adjusted.
2. Multiple rolls of paper-plastic bags of different widths can be loaded at once, enabling simultaneous cutting and sealing of multiple rolls. 
Operating System:
1. 7-inch LCD capacitive touch screen.
2. Android operating system, with a graphical user interface that allows setting of working parameters, clock, calendar, etc.
3. Has automatic storage function.
4. Comes with a USB interface, facilitating data transmission. 
Temperature Control:
1. Computer servo temperature control: Temperature control accuracy is ±1%. Working temperature can be set from 60°C to 220°C.
2. Rapid temperature rise: From room temperature to 180°C, the temperature rise only takes 40 seconds, highly energy-efficient.
3. Auxiliary cooling: Reduces the waiting time from high-temperature sealing to low-temperature sealing.
4. Safety performance: If the sealing temperature exceeds the set working temperature by ±4°C, the machine will automatically stop working. 
● Parameter checking function: It can display and print parameters such as sealing time, temperature, speed and pressure.
● Energy conservation and environmental protection: Once the set standby time is exceeded, it will automatically cool down to the standby temperature.
