How Does A Multi Lane Stick Pack Machine Work?

Similar to how a vertical form fill seal packing machine works, a multi lane stick pack machine follows the same concept of operation.

In multi-lane stick pack machines, each of the many lanes serves the same purpose. Because of this, it produces a large amount of output.

To put a stick packing in action, follow these steps:

The Unwinding and Transport of Film

Make sure the multi lane stick pack machine is fully operational before starting the procedure. The film that will contain the products is first unwound and relayed by the stick packaging machine. A single film sheet is wound over a rolling stock in the machine.

A film reel’s cross-seal jaw keeps the film material in motion while it unwinds. The stick packaging machine’s film reel is located at the rear, and the cross-seal jaw is at the front.

  • Oriented polypropylene [OPP] 
  • Polyethylene [PE]
  • Paper and Polyethylene [PE]
  • Aluminum and Polyethylene [PE]
  • Nylon and Polyethylene [PE]

Setting up the date stamp on the packaging will be made easier with its help. Together with the printing procedure sensors will detect the eye markings and regulate the seal’s positioning. Possible printer options include:

  1. Ink-jet printers
  2. Simple ribbon printers
  3. Thermal transfer printers

Film Tension

The film is fed through sets of nip rollers at this step. The film is kept under consistent tension by using nip rollers, which provide uniform pressure. It will also help the dancer keep their arm in the right place to work.

On the back of the stick packaging machine is the dancer’s arm, which is a weighted pivot arm. A portion of the dancer’s arm has many rollers. The arm will move up and down as the film unfolds, maintaining tension. That stops the film from swaying side to side.

Film Cutting

Following its removal from the nip rollers, the film will go to the cutting portion. Here, the film is cut into strips by the machine. The capacity of the machine to cut strips corresponds to the number of available lanes.

You may think of these strip packs as separate packaging for the items. Plus, the cutting blades aren’t motorized. The stress from the previous step persists while the film passes through the blades. The blades make contact with specialized rollers to help the cutting action.

Formation of Stick Packs

Once the film has been cut, it will be fed via tubes. For each lane, only one strip may pass. This component forms a hollow tube when the cut film travels over its collar. The film will be folded in half along the tube’s length, making the ends overlap.

If you wish a flat seal, you may arrange the forming tubes to make lap seals, and if you want a seal that looks like a fin, you can set them to make fin seals by joining the inner portions of the outside edges.

Because it uses less film material than fin seals and looks better, the lap seal is the better choice.

Stick Pack Filling & Sealing

At this point, a number of heated vertical seal bars make their way toward the film tube, and when they make touch with the film, the heat will create a vertical seal.

The next step involves the contact of a single horizontal sealing jaw, which creates a top seal on one stick pack and a bottom seal on the next. Following this, the sealing jaws are closed, the bottom stick pack is dropped into the center of the forming tubes, and the products are introduced into the stick pack tube.

Make sure the correct quantity goes into the packets by using:

  • Auger filling system
  • Liquid filling system
  • Volumetric filling system

Final Stick Pack Discharge

When the stick packs are full, the blades approach and cut them. In addition, the jaw of a horizontal seal could develop a notch below it. The outfeed chutes will be used to deposit the cut stick packs. Like clockwork, chutes will open and shut at predetermined times.

The outfeed conveyor system is the next stop for the packs once they exit the outfeed chutes. To better direct and regulate the stick packs, a single outfeed chute could be useful. The next step is for the stick packs to be transferred to other machinery, such as x-raying cases, carton packaging machines, or check weighers.
