Which powder projects these machines fit
These machines form single-serve packs from roll film and fill them with fine, dry powder on several lanes at once. The series listings and the catalog configurations name these powders:
- Beverage and dairy powders: instant coffee, milk powder and creamer, cocoa, matcha and drink mixes
- Supplement and health powders: protein, collagen, probiotics, ginseng, turmeric and pharmaceutical powders
- Food and seasoning powders: chili, curry, corn and tomato powder, and pudding powder
- Non-food fine powders: pigment, cleaning, lubricating, talcum and pearl powder
A listed powder is a starting point, not a record of a trial: your own powder decides the dosing and dust-control scope. Start somewhere else if your project is one of these. Granules such as sugar, salt or instant granules are dosed differently and are covered on the stick pack and sachet family pages. Liquids, sauces and pastes are dosed by pump and have their own page: liquid and sauce stick pack and sachet machines. Retail bags of a few hundred grams or more belong on a vertical form fill seal machine, and powder in ready-made stand-up pouches on a premade pouch filler. All three series start at two lanes, so a single-lane or benchtop project is outside this range.
The three series share one construction. The machine forms, doses, fills, seals and cuts the packs; a photo-eye follows the print mark on the film; a PLC with a touchscreen runs the cycle; the film is pulled by servo; the sealers have independent PID temperature control; and the machine is built in 304 stainless steel. What differs is the seal style and the size range, and that is what the rest of this page compares.
Five inputs to define before comparing machines
Two quotations for the same powder can only be compared when both suppliers worked from the same inputs. Define these five before asking for a proposal. If one is still open, say so: an early enquiry can start with a gap, and the gap comes back as a question before the configuration is fixed.
| Input | What to state | What it decides |
|---|---|---|
| Powder behavior | Free-flowing or sticky, how dusty, whether it absorbs moisture and cakes, bulk density, and whether a blend separates in the hopper. If you cannot describe it with confidence, plan to send a sample. | The auger, agitation, dust extraction and feeding |
| Fill weight and pack size | Target dose in grams, and the finished width and length of the stick or sachet | With the bulk density: whether the dose fits the pack, which seal style is possible and which model size applies |
| Pack style and features | Narrow pour-out stick or flat sachet, cut pattern, tear notch and batch code position | The seal style and the cutting and coding options to quote |
| Target good output | Acceptable packs per minute or per shift, not the cut rate, and how often you change product or pack size | The lane count and model size |
| Film and site | Laminate structure and a printed film sample with its eye mark; supply voltage, phase and frequency; clear height of the room; how powder reaches the hopper; where finished packs go next | Sealing settings, the electrical configuration, the feeder and the discharge |
The project brief checklist adds the remaining site, utility and document details a quotation needs.
Series parameters for multi-lane powder machines
The three tables below give the listed values for each model, grouped by seal style. They are series listings, not results measured on a particular powder. Read them with these conditions:
- Speed for every model is listed as 20–40 cuts per minute. Each cut releases one pack per running lane, so a cut is not one finished pack; the output section below shows the conversion.
- The listed supply for every model is 220 V, 50/60 Hz. State your site voltage, phase and frequency; the electrical configuration for your site is confirmed in the quotation.
- Lanes and bag width are ranges for each model. The lane count and the stick or sachet width for your project are chosen together and confirmed in the quotation.
- Fill weight range, fill accuracy and compressed air consumption are not part of these series listings. They are set from your powder and pack and stated in the quotation.

Stick pack, three-side or four-side seal: choose by finished pack size
Start from the finished pack you want to sell, then check which series lists that size. The ranges below are the widest each series lists. In the stick and three-side seal series that is the range of the largest model, and the smaller models stop at a lower width, as the tables above show. The forming parts and lane layout for your exact size are confirmed in the quotation.
| Listed value | Back-seal stick (BF) | Three-side seal (F) | Four-side seal (SF) |
|---|---|---|---|
| Pack style | Narrow stick with a back seal and two end seals | Flat sachet sealed on three sides | Flat sachet sealed on four sides |
| Finished width (mm) | 20–105 | 25–110 | 50–125 |
| Finished length (mm) | 50–150 | 50–150 | 45–160 |
| Lanes by model | 2–4 / 3–10 / 4–16 | 2–4 / 3–10 / 4–16 | 2–4 / 3–10 / 4–16 |
| Machine weight (kg) | 500–800 | 500–800 | 650–1000 |
| Machine length (mm) | 700–1650 | 700–1650 | 1610–1956 |
| Machine height (mm) | 2680–2950 | 2550–2650 | 2880–3100 |
Read your finished width and length against these bands, which follow from the table:
- Width 20–24 mm: only the back-seal stick series lists it.
- Width 25–49 mm: back-seal stick or three-side seal. For a narrow pour-out pack, start with the stick series; for a flat sachet, start with the three-side seal series.
- Width 50–105 mm: all three series list it. Decide by pack style first, then compare the length range, machine size and weight.
- Width 106–110 mm: three-side or four-side seal. Width 111–125 mm: four-side seal only.
- Length 45–49 mm or 151–160 mm: only the four-side seal series lists it.
When your size fits two series, do not choose by the listing alone. Ask for both proposals for the same powder, dose and film, or compare them in a sample test. The difference you can already see is machine size: the four-side seal models are listed heavier (650–1000 kg against 500–800 kg) and longer (1610–1956 mm against 700–1650 mm) than the stick and three-side seal models with the same lane range.
For a flat four-side seal powder pack, the catalog's four-side seal sachet configuration for protein mix lists an independent servo auger for each lane.
Choosing the model and lane count
Within a series, the model follows from two numbers: the finished width of one pack and the number of lanes you need. The maximum film width is the ceiling, because all lanes are cut from one film reel; seal margins and trim also take film width, so the supplier works out the exact lane layout from your pack drawing. The small models are listed for 2–4 lanes, the mid-size models for 3–10 and the largest for 4–16.
More lanes do not by themselves mean more good packs. Each lane adds a dosing unit to set, clean and check. Settle the finished width and the good output you need first, then ask for the lane count and model that deliver it, with the conditions behind the figure. To see what a higher lane count involves, look at the eight-lane protein powder configuration.
Check the site before you shortlist a model:
- Electrical supply: the series are listed at 220 V, 50/60 Hz. Give the voltage, phase and frequency at the machine position, and the electrical configuration for your site is stated in the quotation.
- Clear height: the listed machine heights run from 2,550 mm (LV-680F) to 3,100 mm (LV-980SF). Add the space for the powder feeder above the hopper and for maintenance access, and send the clear height of the room.
- Floor space and weight: the four-side seal models are the longest and heaviest of the three series. Send a layout drawing with the machine position and the route into the room.
- Compressed air: no consumption figure is listed for these series, so state what your site can supply at the machine position.
What 20–40 cuts per minute means for your output
A cut is one cross-seal and cut across the film. Each cut releases one pack from every running lane, so packs formed per minute equal cuts per minute multiplied by the number of lanes.
Hypothetical example: at an assumed 30 cuts per minute on 6 lanes, the machine forms 30 × 6 = 180 packs per minute. This is a calculation, not a rating for any model. It makes no allowance for rejected packs, film changes, cleaning or stoppages, and the cut rate itself depends on your powder, fill weight and pack length.
The good output you plan with is lower than the packs formed. These factors reduce it:
- How evenly the powder flows into each auger, which sets how many packs are rejected for weight
- Fill weight and pack length, both of which the cut rate depends on
- Powder on the seal area, which leads to rejected seals
- Stops for film reel changes and for cleaning between products
- Downstream equipment that cannot take the full output of all lanes
When you compare quotations, ask each supplier whether its speed figure counts cuts, packs formed or good packs, and on which powder, fill weight and pack length it was measured. Convert every offer to packs formed per minute at the stated lane count, then compare the conditions behind each figure.
Dosing and dust control for powders
The powder stick and sachet configurations in the catalog list auger dosing, where a screw measures each dose by its turns. Several list an independent servo-driven auger for each lane, so one lane can be trimmed without changing the others. The dosing unit for your series and powder is set per project: ask the quotation to name it, say how each lane is adjusted and say how the fill is weighed.
Dust matters because powder on the cross-seal area can spoil the seal. Some configurations list negative-pressure dust extraction at the forming tube and the cross-sealing jaws.
These options are listed on individual configurations. Ask whether each one applies to the series and lane count you are quoted:
- Dust extraction at the forming tube and sealing jaws, listed on drink mix stick packs with dust extraction and on a probiotic configuration
- Nitrogen flushing for oxygen-sensitive powders, listed on a coffee stick pack configuration and on probiotic stick packs with nitrogen flushing
- Anti-segregation dosing for beverage powder blends whose ingredients differ in particle size
- A vacuum feeder that refills the hopper from bulk bags
- Ribbon, hot-stamp or laser date coding, and an easy-tear notch device
- Straight, zigzag or rounded cuts with a tear notch
Fill accuracy depends on the powder, the dose and the dosing unit, so no figure is given here for the series. Ask the supplier to state the accuracy for your powder and dose in the quotation, together with how it is measured: how many packs per lane are weighed, against which target, and over what run.
Sample testing: what to send and what it settles
A sample test is worth arranging when the powder is sticky, very dusty or absorbs moisture, when the dose is small or the tolerance tight, when the film has not been run before, or when your pack size sits between two series. Agree quantities and shipping with the team before sending:
- Powder from a normal production batch, with its storage conditions
- Roll film in the production specification, printed if the eye mark matters
- A safety data sheet for chemical or otherwise hazardous powders
- A finished pack sample or drawing with the target fill weight
Fix the measurements before the run, so the result answers your selection question:
- Fill: how many packs per lane are weighed, against which target and tolerance
- Seals: a visual, manual or leak check that you specify
- Output: packs formed or good packs, over a timed run, at a stated lane count
A short test shows how your powder and film behave and helps settle the configuration. It does not by itself establish long-term output, the result with another powder batch or film, or the performance of units that were not part of the test. Which configuration a test can run on, and what you receive afterwards, are agreed with the team for your project. The sample testing preparation page covers shipping, records and test limits in more detail.
Downstream: counting, cartoning and case packing
Multi-lane powder machines can continue to bagging or cartoning, weight checking, case packing, case sealing and robotic palletizing. A counting discharge conveyor can take the place of a separate bag-sorting machine. Say in the enquiry where the packs go after the machine and how many go into each carton or bag, so the discharge and counting are quoted with the machine.

Questions buyers ask about powder stick and sachet machines
Can one machine make both stick packs and flat sachets?
The three series are listed separately by seal style. Do not assume one machine switches between a back-seal stick and a three- or four-side seal sachet. If you need both, ask for it to be confirmed in writing in the quotation, with the parts each change requires.
Can the same machine run granules as well as powder?
Granules are dosed differently from fine powder. If you need both on one machine, say so at the start and have the quotation confirm in writing how the changeover works.
Can I change stick width or fill weight later?
Pack width is tied to the forming parts and the lane layout, and fill weight to the dosing parts. List every width and fill weight you plan to run, and ask the supplier to name the parts and the time each change requires.
Is a milk powder sachet machine different from a coffee or protein powder machine?
Not in the seal style or the series. The series listings name coffee and milk powder for all three seal styles, and the catalog's milk creamer and coffee configurations both belong to the LV-400BF series. What changes with the powder is the dosing, dust control and feeding; the milk creamer, coffee and protein configurations linked above show how those options vary.
Can lanes be added after delivery?
Do not assume so. The frame, film width and dosing layout limit it, so ask for it to be confirmed in writing before you order.
Next step: send your powder project
Send the powder or its description, with its bulk density if you have measured it, the fill weight, the finished stick or sachet size, the seal style you prefer, the good output you need and your supply voltage. Leave blank anything you have not decided. The team reviews which series and lane count fit and whether a sample test is needed, and comes back with a configuration proposal or a sample-test plan to discuss.
