Which powders suit a powder stick pack machine?
Instant coffee mixes, collagen and powdered beverages are the usual starting points, but the product name alone does not settle the configuration. A powder stick pack machine links metering, film handling, forming, sealing and cutting in one cycle, and every step reacts to how your powder behaves. Send the actual formulation or a representative sample with the smallest and largest intended dose, and explain how the powder reaches the machine and how long it sits in a hopper before packing.
The same serving weight can occupy very different volumes. A light, aerated powder needs more pack space than a dense one at the same weight, and a powder that settles during a run may discharge differently from the auger an hour later. Describe any clumping, dust, moisture pickup or uneven discharge you already see in production. Those notes steer the discussion toward the feeding and filling arrangement instead of a machine picked from a photograph or a nominal speed.
For electrolyte drink blends, connect moisture exposure and cleaning conditions to the contact-part and dosing review before defining the sample trial. The electrolyte application guide sets out those checks.

| Powder behavior | What it changes on the machine | What to send |
|---|---|---|
| Free-flowing | Feeds steadily to the auger; the main checks are dose and seal cleanliness | Sample and minimum and maximum dose |
| Cohesive or poorly flowing | Can bridge in the hopper and fill unevenly, so the feeding arrangement matters as much as the auger | Sample, bulk density and notes on clumping or bridging |
| Very fine or dusty | Dust can reach the seal area; dosing-to-sealing timing and dust extraction are reviewed | Sample and a description of the dust seen in production |
| Light or aerated | Needs more pack volume at the same weight, which can limit the dose one stick holds | Bulk density and the largest dose |
| Moisture-sensitive | Can cake in the hopper; film barrier and the time powder sits exposed before packing are reviewed | Storage conditions and how long powder waits in the hopper |
| Blend of coarse and fine particles | Can separate in the hopper, so the composition of each dose can drift | Blend description and any separation already seen |
How does auger dosing work on a stick pack machine?
An auger is a rotating screw that meters powder into the filling path of each lane, and the screw, its outlet and the drive settings are chosen around your material and dose. In the four-lane reference configuration every lane has its own auger. Ask how powder is distributed to the augers, which adjustments the operator can make, and, if servo control is proposed, which movements it drives and how the settings are saved for each approved recipe.
Steady supply to the augers matters as much as the screw itself. Ask how the hopper and replenishment arrangement handle your powder as the level falls from nearly full to low, since fill weight can drift as the head of powder above the screw changes. If additional feeding equipment is needed, the quotation should name who supplies it and who controls the interface. In a sample trial, take fills after replenishment, after a pause and during sustained running, and keep those samples apart so each adjustment addresses the condition that caused it.
Auger dosing is the usual starting point for fine, aerated or poorly flowing powders, which is why the reference configuration gives each lane its own servo auger. Free-flowing granules are normally dosed with volumetric cups or vibratory feeding instead, as described on the granule machine page. A product can sit between the two, so the sample decides: send the powder and run the trial before fixing the dosing method.

How does a powder stick pack machine make a stick?
Every lane repeats the same sequence in each machine cycle, and the auger is only one step of it. A printed film reel is unwound and slit into one narrow strip per lane, each strip is folded around its forming tube and closed with a back seal, the auger doses powder down the tube, and the end-seal jaws and knife close and separate the stick. The list below follows that order.
Faults in a finished stick usually trace back to one step. Weight variation points to the auger and the powder supply, powder in the end seal points to the timing between dosing and sealing, and a cut in the wrong place points to print registration. Sample by lane and by step during a trial, so each correction goes to the step that caused the fault. The working-principle guide follows each stage in more detail.
Related reading: How a Stick Pack Machine Works
- Unwinding: the printed reel feeds the machine, with print registration kept in step with the cut
- Slitting: the web is divided into one strip per lane
- Forming: each strip is folded around its forming tube and closed with a back (fin) seal along its length
- Dosing: the servo auger for that lane meters the dose down the tube
- End sealing: jaws seal across the stick, closing the filled stick and the bottom of the next one
- Cutting: the knife separates the sticks with a straight, zig-zag or round-corner cut, with an optional tear notch or a perforated chain
Lane count and film width on a powder stick pack machine
Lane count, finished stick width and film reel width are fixed together. Reel width is approximately the unfolded film strip width per lane multiplied by the lane count, plus edge allowance. Unfolded strip width is different from finished flat pack width: for a back-seal stick it is approximately twice the finished width plus the film consumed by the back seal. Use the approved web-layout drawing for the actual reel order, including the specified seal construction and trim.
The four-lane reference configuration makes sticks about 15–30 mm wide, with the width set by the forming tube; other lane counts are quoted per project. Size the lanes from the accepted sticks per minute you need and the rate one auger can hold on your powder, and let the trial confirm that rate. A dusty or cohesive powder that needs a slower cycle may justify an extra lane, while a range with frequent recipe changes may not keep extra lanes busy.
Ask the quotation to state the lane count, the stick widths each forming set covers, the maximum film reel width and the reel core size the unwinder accepts. Your film supplier can then quote and print against the same figures, and a later change of stick size can be checked against them.

Film forming, filling and sealing in a multi-lane machine
In a multi-lane machine the film is divided into parallel webs, each wrapped around a forming tube, and the dose has to drop and settle before the end seal closes and the knife separates the stick. Review the proposed lane count against the pack drawing, dose volume and film roll specification. The four-lane platform is the starting point for that discussion; the configuration you actually buy should be written into its own technical agreement.
Powder reaching the seal area is the defect to watch most closely in a powder trial. Observe the product drop, the settling time and the timing between filling and sealing. Dust extraction is an option in the reference configuration, so if it is proposed, ask what it covers and where it stops. Raising jaw temperature does not cure powder trapped in a seal. Inspect packs from every active lane and keep examples of good and defective packs, so each setup change is judged against physical evidence.
Nitrogen flushing is the other option named in the reference configuration. If it is proposed for an oxygen-sensitive powder, ask which part of the pack and film path it covers, how residual oxygen is checked and who owns that check. Barrier film and nitrogen together do not prove shelf life; that needs evidence on the packed product.
For an oxygen-sensitive powder, the nitrogen-flushing guide below explains forming-tube outlet position, gas-use calculations and the residual-oxygen record to agree before a sample trial. Define the oxygen target and measurement timing together with the product and film.

Discuss this configuration
Discuss on WhatsAppFilm and pack size for powder stick packs
Most powder projects start from a heat-sealable laminate such as PET/PE, PET/AL/PE, NY/AL/PE or paper/PE and a stick within the reference ranges of about 15–30 mm wide and 50–180 mm long. Fix the size on a drawing with finished width, length, seal areas, tear notch or other opening feature and print position, and state whether the dimensions describe the finished stick or the flat film. Check internal volume with filled samples, especially when the range runs from a small serving to a larger portion: an empty sample can look right and still be hard to fill, close or empty.
Give the film supplier's material code, structure, thickness and roll dimensions so feeding, registration and sealing are reviewed on that exact material. If you want to compare a second film, keep its trial results separate; laminates that look alike do not always seal alike. Judge finished-pack appearance and opening against your own quality checks. Barrier performance and shelf life need evidence for the complete product and package, and a clean run on the packing machine does not provide it.

Powder packaging machine choice: stick pack, VFFS pillow bag or premade pouch
For powder packaging, a stick pack and a vertical form fill seal (VFFS) pillow bag are two roll-film routes that suit different portions. A multi-lane stick pack machine slits a wide film web into several narrow strips and makes slim single-serve sticks side by side, about 15–30 mm wide and 50–180 mm long in the reference configuration. A VFFS machine turns a roll of film into individual filled bags: it forms the film around a tube, fills it and seals it, leaving a pillow bag with a longitudinal seam and sealed ends. Settle the pack before the machine, because the two routes use different forming parts and tooling.
Start with the dose and the powder. Divide the dose mass by the measured bulk density to get an approximate volume, then check whether that volume fits a stick of the size above once the seals and filling clearance are taken off; the stick pack dimensions guide shows the method. The four-lane powder reference covers about 1–20 g per stick, and around 30 g needs different auger tooling and a trial. A pillow bag is judged by its filled shape and volume, not by the empty bag width, and a light, aerated powder needs more pack space than a dense one at the same weight in either format. Use filled samples of your own powder instead of the nominal dose.
Choose a stick pack when the pack is a single serve, the dose sits within the stick range and the product is poured or stirred out in one use, as with a coffee mix, collagen or a powdered drink. It also suits lines that need many identical packs, because several lanes form, fill, seal and cut together; about 120–160 sticks per minute on four lanes is a reference range, confirmed by a trial for your product. Look at a VFFS pillow bag when the portion is larger than a stick can hold, or when the pack is meant to carry more than one serving. The powder questions stay the same on both routes: VFFS machines dose fine or poorly flowing powders such as coffee powder, seasonings and baking mixes with an auger, and screw tooling and dust control depend on the powder, so send a sample, the bulk density, the dose range and any dust you see near the seals.
A premade pouch is the third route. A pouch converter makes the stand-up or zipper pouch, and a pick-fill-seal machine opens, fills and seals it. It is chosen when the pack needs a stand-up base, a zipper or a spout, and any size change needs the gripper, sealing and change-part requirements confirmed for the proposed platform. A stick pack stays the better fit for a single serve that is torn open once.
This page covers the stick pack route only. VFFS pillow bags and premade pouches use different platforms and are outside the reference ranges here. If either is the pack you need, identify it separately in your brief. If the format remains open, compare the routes with the same powder sample and filled pack samples, judging accepted output, seal cleanliness and handling after the machine.

| Question | A stick pack tends to fit when | A VFFS pillow bag tends to fit when |
|---|---|---|
| Portion | Single serve within about 1–20 g per stick in the reference configuration | The portion is larger than a stick can hold, or covers more than one serving |
| Pack shape | A slim back-seal stick about 15–30 mm wide, made in parallel lanes from a slit film web | A pillow bag with a longitudinal seam and sealed ends, sized from the filled volume |
| Powder volume | Dense or free-flowing powder whose volume fits a narrow stick | Light, aerated powder that needs more pack space at the same weight |
| Dosing and output | An auger per lane; about 120–160 sticks per minute on four lanes as a reference range | An auger dosing unit for fine or poorly flowing powders; speed is outside this page's ranges and is confirmed separately |
Recipe changeover and cleaning access
Changeover planning starts with the list of powders that will share the machine and the order you intend to run them. A new flavor, serving size or formulation can mean different settings, a different auger or extra cleaning. Ask which components are removed, how they go back together and which settings are checked before production restarts. Put access to the hopper, augers, outlets and the corners where spilled powder collects on the review list.
Your product and quality team should define the cleaning method, and the method should not assume every stainless part tolerates the same treatment. The reference configuration uses a SUS304 frame with 304/316L product-contact parts, so check which grade each contact part has on the machine you are quoted. Count drying, reassembly, line clearance and the first accepted packs in the changeover estimate. For frequent recipe switches, consider a spare set of contact parts, labeled and stored so operators can tell a clean set from one still waiting for inspection.

How fast is a four-lane powder stick pack machine?
As a reference range, a four-lane powder stick pack machine runs about 30–40 cycles per lane per minute, roughly 120–160 sticks per minute, using an independent auger for each lane, a single forming and sealing section and a PLC with touchscreen. Fine, sticky or dusty powders usually sit toward the lower end, and product-specific losses come off that figure.
These four-lane configuration ranges support the initial equipment comparison. The quotation specifies output, fill range and dose accuracy for the agreed product, film and pack size; factory acceptance testing checks those requirements under recorded conditions.
Scroll horizontally to see all columns. Keyboard: focus the table and use the arrow keys.
| Parameter | Typical reference range |
|---|---|
| Lanes | 4 in the reference configuration; other lane counts are quoted per project |
| Output | About 30–40 cycles per lane per minute, roughly 120–160 sticks per minute |
| Fill weight | About 1–20 g per stick; around 30 g needs different auger tooling and a trial |
| Stick length | About 50–180 mm |
| Stick width | About 15–30 mm, set by the forming tube |
| Film structures | Heat-sealable laminates such as PET/PE, PET/AL/PE, NY/AL/PE and paper/PE |
| Seal and cut | Back seal; straight, zig-zag or round-corner cut, with an optional tear notch |
| Power supply | About 3.5–4.5 kW; 220 V or 380 V, 50/60 Hz, matched to the destination grid |
| Compressed air | 0.6–0.8 MPa |
| Machine weight | About 650 kg |
| Construction | SUS304 frame with 304/316L product-contact parts |
| Options | Dust extraction and nitrogen flushing |
Measuring accepted output in a sample trial
Accepted finished packs per minute, measured over a stated shift pattern, is the output figure to plan around. Cycle rate multiplied by lane count leaves out film splices, hopper refills, start-up checks, cleaning and downstream handling, all of which reduce what reaches dispatch. Ask for the trial duration and the reject count next to any reported speed, so a short demonstration is not read as a production forecast.
Before testing, agree on the fill-weight sampling method, lane identification and acceptance limits. Keep start-up, steady-running and restart samples in separate bags. Run the most demanding recipe and film as well as the routine product if they differ. Log every adjustment before collecting the next sample set. The result is a handover record operators can return to when fill weight or pack appearance changes months later.
Documents to list in a powder machine quotation
A quotation covers only the documents it names, so list the ones you need in your brief. Useful items are a written configuration list naming the augers, lane count, pack range and options such as dust extraction, plus the agreed factory acceptance criteria and the results recorded when your machine is tested against them.
Operating instructions, a recommended spare-parts list and wiring diagrams for the control cabinet are other common requests; check which of them the quotation actually includes. Market-specific compliance paperwork is a separate question, so raise any requirement directly rather than assuming it arrives with the machine. File whatever you receive with the sample-trial results so installation, training and later service all refer to the same configuration.
From powder trial to quoted configuration
Define the supply boundary around the powder packer. A feed system must maintain material supply to every auger, while discharge handling must clear accepted packs at the proposed rate. Mark coding, conveying and inspection as machine-side or buyer-side tasks on the line drawing, then check space and utilities against that combined arrangement.
Compare quotations on the tested material and format, supplied components, change parts, trial criteria and documentation, together with training, installation planning and the proposed spare-parts list. If the formulation or pack changes after the order, go back to the recorded trial conditions to decide what needs retesting. Enquiries are handled on WhatsApp through the request-a-quote page, and a single-machine order is quoted the same way.

Common Questions
Which types of powder can go into a stick pack?
Free-flowing, cohesive, very fine and moisture-sensitive powders can all be packed in sticks, but each changes the configuration. Cohesive powder needs feeding that keeps the auger supplied, dusty powder needs attention at the seal area, a light powder needs more pack volume and a moisture-sensitive powder needs suitable film and short exposure in the hopper. The table in the first section lists what to send for each.
How is a powder stick pack different from a sachet or a pouch?
A stick is narrow and sealed along its back, while a sachet is wider and often sealed on four sides; a stand-up or zipper pouch is made on a separate platform. Each format uses different forming parts. The stick pack vs sachet guide compares the formats, and the section above on stick packs, pillow bags and premade pouches covers the machine choice for powders.
Can one powder stick pack machine run several different powders?
Yes, a shared platform can run several recipes, provided each is checked for settings, cleaning and dose. A powder with a very different density or a much larger dose may need another auger or its own trial. List every powder and dose you plan to run, so change parts and cleaning steps are scoped before the order.
What fill weight can a powder stick pack machine handle?
The four-lane reference configuration covers about 1–20 g per stick. Around 30 g needs different auger tooling and a trial, and a bulky powder can run out of pack volume before it reaches the target weight. Send your minimum and maximum dose with a sample so both ends of the range are tested.
Why does powder end up in the seal of a stick pack?
Usually the dose is still falling or dusting when the end seal closes. The filling-to-sealing timing, the fill height in the stick and very fine particles all contribute. Fixes come from timing, pack length or dust extraction rather than higher seal temperature, and each change should be checked on packs from every lane.
Does a powder stick pack machine need compressed air?
Yes. The four-lane reference configuration lists 0.6–0.8 MPa of compressed air, alongside a power supply of about 3.5–4.5 kW at 220 V or 380 V, 50/60 Hz. Compare your plant supply with these reference figures and with the utilities stated in the final quotation before planning installation.
Should I choose a stick pack machine or a pillow bag machine for powder?
Choose by portion. A stick pack suits a single serve within about 1–20 g per stick in the reference configuration; a larger or multi-serve portion points to a pillow bag or a premade pouch, which are different machine platforms outside this page's reference ranges. Send your dose, bulk density and the pack you have in mind, and compare the routes on filled samples.
Can a stick pack machine fill cohesive or poorly flowing powder?
Auger dosing is the usual starting point for such powders, but it has to be proven on yours. Cohesive or aerated powder can bridge in the hopper, fill unevenly and dust at the seal. Send a representative sample with its bulk density, and judge the trial by fills after replenishment, after a pause and during sustained running, not by one stable stretch.
How much does a powder stick pack machine cost?
The quotation follows the lane count, the auger and hopper arrangement, the pack format, options such as dust extraction or nitrogen flushing, and the supply scope. The price guide explains the cost drivers. Send your powder, dose range, pack drawing and target accepted output, and compare quotations on one scope list rather than on the headline price.
