Ultimate Stick Machine Work

Stick Packaging Machine

Stick Machine Work; Stick pack machines are becoming more popular as an automated solution for packaging demands in many different industries.

Consumers choose stick packs over other packaging options for single-serve foods because they are easy to use, portable, and handy. Nowadays, a wide variety of industries use multi-lane stick pack machines to package various types of liquid and powder products.

Because of their space-saving capabilities and fast productivity, stick-pack machines are in high demand of manufacturers and co-packers. However, we would want to know how the stick machine work. This guide will show you how to use a stick pack machine to make many individual packets from a single roll of film.

Stick Machine Work

As with vertical form fill seal packaging machines, stick pack machines work by cutting a roll of film into many stick packs, filling the bags with goods, and sealing them vertically. Each lane can process 80 bags per minute. A single stick pack machine has the capacity to make 1,600 stick packets per minute, while machines with 20 lanes can do even more. In a single second, that’s more than 26 sticks!

Let us take you with it through each step:

Transport and Unwinding of Film

The stick pack machine often employs rollstock, which is essentially a single sheet of film wrapped around a central core. At the machine’s back, you’ll find the film reel, which is unraveled from the film. At the head of the stick machine, you’ll find the cross seal jaws, which unwind the film. Grippers, another name for cross seal jaws, take hold of the film at its very edges and feed it linearly towards the machine’s finish.

Optional Printing

When you install a date-stamping equipment on the machine, the film runs around an alignment roller. As a result, the horizontal seal may be more precisely register the product’s date stamp.

Threading the film through a sensor that reads eye marks and controls the horizontal seal’s positioning relative to the film’s printing is the process.

Film Tension

After that, a series of nip rollers feed the film. In order to maintain the correct working posture for the dancer’s arm, the nip rollers provide uniform pressure to the film, which helps to maintain a steady tension.

When unwinding the film off the roll, it goes over a dancer’s arm—a pivot arm at the back of the machine that is weighted—during unwinding. You may find some rollers in the arm. An automatic film tracking sensor makes sure the film doesn’t sway from side to side while transporting, and the arm raises and lowers it to maintain tension.

Film Cutting

The film travels from the nip rollers to the slitter assembly, which is responsible for cutting it. At this stage, the number of lanes on the stick machine determines how the huge roll of packing film is sliced into strips. Each stick pack is built from these strips.

This phase is completed with non-motorized cutting disk knives. As the film is wound around the blades, which are still under tension, a roller with a specific design contacts the film. The process of pulling the film through this assembly separates it into single stick packs.

Forming Stick Packs

The sliced film then goes through a series of forming tubes, one for each lane. By the time the cut film reaches the shoulder or collar of each forming tube, it is wrapped around the tube to create a stick-pack shape, with overlapping edges.

Both lap and fin seals are possible with the configuration of the forming tubes. The difference between a lap seal and a fin seal is that the former creates a flat seal by overlapping the film’s two outside edges, while the latter creates an outward-pointing seal by coupling the insides of the two outer edges. Because it requires less material and looks better than a fin seal, a lap seal is the ideal choice.

Filling and Sealing Stick Packs

Hot, multiple-barreled vertical sealers—one for each lane—move ahead until they touch the film’s vertical overlap as soon as the film stops moving. To create a vertical seal, the seal bar pushes down on the forming tube.

After that, the top and bottom seals of two separate stick packs are formed by a single horizontal sealing jaw. The product is filled into each bag as the sealing jaws are closed by lowering it down the middle of the forming tubes. To ensure that each stick gets the exact amount of product it needs, a filling machine such as a liquid pump, auger filler, or volumetric filler measures and releases the precise amount of product.

Stick Packet Discharging

Following product discharge into each stick pack, the blade of the knife moves forward and slices open the bag or cuts a notch in the horizontal seal right under its jaw.

At regular intervals, a flap in the outfeed chute opens and shuts, releasing the final stick packs into a receptacle or down an outfeed conveyor. You have the option to use separate outfeed chutes if you want a more direct and precise discharge of stick packs.

X-ray machines, check weighers, , case packaging, and carton packing machines are all downstream processes that may take the final products.

What Kinds of Goods Can a Stick Pack Machine Pack?

stick pack machine Industry Applications

The stick machine is useful for packing a broad range of products, such as:

  • Nuts
  • Mayo
  • Mints
  • Mustard
  • Ketchup
  • Candy bars
  • Granola bars
  • Instant coffee
  • Detergent pods, etc.

You can pack a lot of different products using a stick pack machine. For both food and medicine, stick pouches are ideal. Instant coffee and medicine powder, among other products, are in an environment with little explosion risk in this packaging.
