Two kinds of Nonwoven fabric Stick Sachet MachineTwo kinds nonwoven fabric Stick Sachet MachineEquipment Feature:

  1. An automatic granule packing machine can finish the process of conveying bags, bag making, filling, weighing, sealing, cutting, counting, lot number, etc.
  2. Bilingual display screen control system, stainless steel cabinet. Set up the required data(including filling, weighing, bag size, etc) in the visible settings, and the control system’s automatic optimization matches with all the programs to achieve the best packing speed precisely.
  3. Stepper Motor control, this system has the advantage of being precise, needless to adjust the other parts.
  4. It has a color system controller, so you can get the complete trademark design.
  5. Suitable for complex film tin foil and other packing material.Fine packaging performance, low noise, clear sealing texture, and strong sealing performance.


  1. The machine is according to the screw to determine the volume for each bag, we can change the unit volume in a certain range by adjusting the PLC parameter and the measuring cup. The black line is used for Nitrogen-filling before and after bag filling.
  2. Ultrasonic controller performance is stable, and the sealing model has an even temperature so bag sealing is tight and nice, helping you get more customers. Different nonwoven materials, soft or hard, thickness will need different perfect sealing temperatures so we will adjust the ultrasonic controller according to your exact material.
  3. Bag former it’s hand-made from aluminum, so it’s very smooth and anti-rust. If the bag former is welded from several pcs of iron then its rough surface and easily rust. It will get the film stuck and affect the procedure. You can change the bag former to make a different-width bag.
  4. The sealing model and cutter sealing mode are made of titanium steel which is wear-resistant, ultrasonic sealing, and easy to operate and maintain. Double nonwoven packing avoids material leakage, and the Sealing pattern can be customized according to your requirements.


For the different thicknesses of hard or soft Non-Woven fabric, there is a relevant perfect ultrasonic frequency to make the tightest sealing. So we suggest that use your exact Non-Woven fabric to test the machine for you.

After Sales Service

1. One-year warranty and free lifetime technique support.

2. Free spare parts would be supplied if the machine has broken within the warranty period.

3. After the warranty period, the spare parts for replacement are offered based on a certain charge.


1  Film/paper pull off

Cause The packaging material has joints, the paper feeding motor does not rotate, and the rough edge with too large a breaking. The proximity switch is damaged. Poor line contact. Main motor reverse

Solution Remove the unqualified paper section, replace the proximity switch, repair the circuit, and change the phase of the main motor wiring

2 Lax sealing

Cause 1. The flatness of the mold and wave head is not enough. 2. Ultrasonic overload. 3. Transducer failure. 4. The parameters of the ultrasonic controller are incorrect.

Solution 1. Adjust the four screws after the mold. 2. Adjust the wave-generating current. 3. Replace the transducer. 4. Adjust the parameters of the ultrasonic controller.

3 Don’t pull bags

Cause  The initial bag-pulling switch has no response. The trigger distance is not enough. The contactless switch is broken.

Solution Check whether there is signal output without contact. Under the verification “state”, observe the change of PX2 height and adjust its trigger distance

4 Failure shutdown after bag pulling

Cause  The color code is not adjusted well, and no color code is detected

Solution Adjust photo-electric

5 Abnormal film supply during shutdown

Cause No packaging film

Solution Supply packaging film

6 Temperature control indication jump

Cause The thermocouple is disconnected and has poor contact

Solution Replace the fastening thermocouple

7 Temperature control indication does not rise

Cause The electric heating, the tube is burnt out or the fuse is blown

Solution Replace the electric heating pipe or fuse

8 Cutting knives constantly

Cause The cutter is not flat, the pressure of the cutter compression spring is not enough, and the cutter is worn.

Solution Adjust the trimming tool or replace it

9 The bag is blocked above the cutter

Cause The bag pulling time is incorrect, and the position of the upper bag baffle is incorrect

Solution Adjust the bag pulling timing to pull the bag when the cutter is fully opened, and adjust the position of the bag retaining plate

10 Machine does not start

Cause The fuse is blown, the main power switch is not connected, and the emergency stop switch is not reset

Solution Replace the fuse. Check the main power switch. Emergency stop switch reset
