Brief introduction of liquid packaging machine

The liquid packaging machine is suitable for packing milk, soy milk, soy sauce, vinegar, butter, and various liquids. The machine can automatically complete film-forming, measuring, filling, sealing, cutting, counting, and printing the production date. Stainless steel is used for the contact part of the machine and the material. The packaging form is back seal. The metering method adopts valve plug pump filling. The packaging film is sterilized. The finished bag is beautifully packed, safe, and hygienic. The packaging material adopts heat-sealable plastic film such as polyethylene or PE.

Main structures of liquid packing machine

In taizy company, the automatic liquid packing machine mainly concludes film former, vertical seal, film pulling, discharge lower pallet, control panel, stainless steel, pump.

Film former can fold the flat plastic film into product packaging. Vertical seal makes the packaging film into back-seal style. Then, the film pulling can convey the plastic film steadily. The packed bag of liquid comes out from the discharge lower pallet, which can cushion the product's gravity and prevent damage. The control panel can control the sealing temperature, heating, sterilization, and counting. You can adjust the switch according to your needs. Liquid materials can be transported quantitatively. The weight of the transported liquid is accurate. The pump has a backflow effect. The valve is open when the machine is working, and the excess liquid will flow back. The liquid packaging machine is made of stainless steel. Therefore, It is durable.

Working principle of liquid packaging euipment

The liquid material passes through the top of the packaging machine from the feeding box. The liquid material will flow into the feeding barrel after being measured. The packaging material (such as polypropylene film) on the roll is guided into the outer wall of the feeding cylinder by three traction rollers. Then, it is gradually wound into the abutting cylinder by the lapel bag former and a pair of continuous reverses on the longitudinal sealer. The rotating longitudinal sealing roller is heated and pressurized at the butt joint to heat seal it firmly in the longitudinal direction.

The longitudinal sealing roller can play the role of heat sealing. Also, It can pull and feeds the film at the same time. The material to be packaged is introduced into the plastic bag by the filling cylinder composed of the feeding trough and the inner wall of the former. Transverse heat sealing can form a transverse seal. When the rotary cutter on the cutting device contacts the fixed cutter, the transverse seal is cut along the centerline. It aims to complete the top seal of the packaging bag and the bottom seal of the next bag. The bottom-sealed packaging bag can be directly fed into the bag, and then move to a station to complete the top-seal sealing. After that, cut through the cutting device to complete the packaging process. Last, the transport device transports the product. The entire packaging process is fully automatic and continuous.


  1. Can this machine pack carbonated drinks?
    The liquid bag packaging machine cannot pack carbonated drinks. If you want to pack carbonated drinks, you can buy a liquid filling machine.
  2. Can the liquid packaging machine print the date?
    Yes. This machine is equipped with a coding device to realize the production date coding. The coding format is steel stamp coding.
  3. How much is the liquid bag packaging machine?
    The machine has different models. Also, the machine can also be customized according to your needs. So the price is different. You can contact us for more details.
  4. Does this machine have a UV sterilization function?
    Yes, ultraviolet rays sterilize the packaging film.
  5. How exactly does the liquid packaging machine load? Do you need an air compressor?
    The pump draws in the loading material and flows in through the pipeline. No air compressor is required.
  6. Are the packaging weight and bag length adjustable?
    There is an adjustment block behind the box. And it can adjust the packaging weight and packaging length.
