The GH240 packing machine is widely used in the product packaging of food, cosmetics, daily chemical products, and other enterprises. Liquid, granule, and powder small bag products are all packaged by corresponding machines.

A. If the bag has no photocell:

Click on the screen on the machine, enter the Parameter Setting interface, and reset the length of the stretched film. You can set the length of your bag as long as it is.

B. If the bag has the photocell:

1. Click the screen on the machine to enter the Parameter Setting interface and reset the length of the film;

2. Enter the Operation Status interface and turn on the automatic color marking function;

3. Adjust the color sensor on the machine. The sensor has two modes, one is a green light and the other is a red light. Generally, we use red light mode for recognition. Move the photocell on the film to align with the sensor, and the light off means recognized. Then start the machine.
