SW-A6: Six-Lane High-Output Sachet Platform
The SW-A6 is a vertical form-fill-seal (VFFS) machine with six parallel lanes. Each cycle produces six 3-side seal sachets simultaneously — film unwinds from a single roll, is cut into six strips by a longitudinal slitter, formed into six pouches, dosed with product, and sealed on three sides (two vertical side seals plus one horizontal end seal per sachet). At 200–300 cycles per minute, the combined throughput is 1,200–1,800 finished sachets every minute, equivalent to roughly 720,000 sachets in an 8-hour shift.
The filling system is selected by product type at time of order: piston pump dosing for liquids and sauces, auger screw dosing for dry powder, and volumetric cup dosing for free-flowing granules. Typical applications include ketchup, jam, honey, sauce, salad dressing, coffee, sugar, salt, MSG, seasoning, and pharmaceutical portion packs. Fill volume is 5–30 ml per sachet; bag width is 30–100 mm; bag length is 50–150 mm.
A PLC with touch screen HMI coordinates film feed, dosing, sealing, and cutting. Temperature controllers manage each sealing zone independently so operators can tune seal quality for different film structures — OPP/CPP, PET/PE, or NYLON/PE. All product contact surfaces are 304 stainless steel. For a 10-lane back seal stick sachet machine, see the SW-B10 ten-column machine. For single-lane liquid sachets with larger fill volume, see the SW-420F collar type liquid machine.

Output Bag Type: 3-Side Seal Small Portion Sachet
The SW-A6 produces a single bag format: the 3-side seal sachet — two vertical side seals plus one horizontal end seal per sachet. Film is unwound from one master roll, slit into six ribbons by longitudinal knives, and formed into six parallel sachet channels. Six 3-side seal sachets are produced in every cycle. This format is the industry standard for single-use condiment, coffee, sugar, and pharmaceutical portion packaging.
Typical output — honey, sauce, and jam in 3-side seal single-serve sachets
3-Side Seal Sachet (Standard Output)
Compatible film: OPP/CPP · PET/PE · NYLON/PE · aluminum foil laminate · plain PE. The machine runs rollstock film only — no pre-formed sachet supply needed. Send your film sample for sealing temperature and dwell time confirmation before production.
Note: This machine produces 3-side seal sachets only. For back seal stick sachets, see the SW-B10 ten-column back seal machine. For 4-side seal sachets, the SW-C6 six-column four-side-seal machine is the matched alternative. For stand-up pouches, see the SW-Y200 premade bag liquid machine.
How the Six-Lane Cycle Works
Each cycle on the SW-A6 produces six finished sachets simultaneously. The four-stage cycle — unwinding, forming, dosing, sealing — runs continuously at 200–300 cycles per minute. Operators interact with the machine through one touch screen HMI; all six lanes are controlled together.
01
Film Unwind & Slitting
Film unwinds from a single master roll mounted at the rear of the machine. Five longitudinal knives cut the film into six equal ribbons. Each ribbon feeds to its own forming station. Servo-driven film pull maintains consistent tension across all six lanes so cut lengths stay uniform throughout a production run.
02
Pouch Forming & Side Sealing
Each ribbon passes over a forming collar that shapes it into an open-top sachet channel. Heated vertical seal bars close the two side seams of each sachet, creating the left and right seals of the 3-side seal bag. Temperature controllers maintain a stable set point per lane so seal strength is consistent across all six sachets.
03
Dosing & Fill
The selected dosing system — piston pump for liquid, auger screw for powder, volumetric cup for granule — delivers the target fill volume to all six sachets simultaneously. Fill accuracy is typically within ±1% for free-flowing products. Fill volume is adjustable from the HMI panel; the same machine can run different fill weights for different SKUs by recipe recall.
04
End Seal & Cut-Off
Horizontal heated jaws close across all six lanes, forming the top and bottom end seals simultaneously. A knife built into the jaw set cuts between each sachet pair to separate finished sachets from the continuous film web. Completed sachets drop onto the outfeed conveyor for downstream collection, date coding, or cartoning.

Five Design Features That Drive Six-Lane Reliability
Multi-lane machines are only as stable as their weakest lane. The SW-A6's design addresses the five mechanical areas that determine lane-to-lane consistency and long-term uptime on high-volume portion-pack production.
① Configurable Filling System
Piston pump, auger screw, or volumetric cup — the dosing module is specified at time of order to match your product. All three options meter simultaneously into six lanes from one central reservoir. Changeover to a different product within the same dosing family is recipe-driven from the HMI.
② Independent Temperature Control
Each sealing zone has its own controller and thermocouple. Side seal bars, end seal jaws, and the film-pull area can be tuned independently. This is critical when switching between OPP/CPP, PET/PE, and aluminum foil laminate — each film has a different optimal sealing temperature window.
③ Six-Column Forming Tubes
Six parallel forming collars shape six ribbons of film into six sachet channels. Tube geometry is matched to your bag width (30–100 mm) at time of order. Forming quality directly determines seal quality and sachet appearance on all six lanes — the forming stage is where multi-lane consistency is won or lost.
④ Touch Screen HMI & PLC Control
One HMI controls all six lanes — cycle speed, sealing temperature, fill volume, bag length, and fault codes are on a single screen. Product recipes are saved so operators can switch between SKUs without manually re-entering parameters. Language and unit settings are configured at time of order.
⑤ Servo Film Pull & Photocell Registration
A servo-driven film pull advances the film a precise distance each cycle for accurate bag length. A photocell reads the print registration mark on the film and automatically adjusts pull length to keep printed graphics aligned on the sachet face. Film waste is minimized even at maximum speed.
Core Parts on the SW-A6
The images below show the feeding, forming, dosing, and sealing parts that matter most when evaluating the SW-A6 for long-term multi-lane operation, film changeover, and maintenance access. Full component list including electrical brands is provided in the quotation sheet on request.
Touch Screen HMI
One central interface controls all six lanes. Stores product recipes for rapid SKU changeover and displays real-time cycle speed, temperature, fill volume, and fault diagnostics.
Temperature Controller Bank
Dedicated controller per sealing zone — side seal bars, end seal jaws, and film-pull area — allows precise heat tuning for OPP/CPP, PET/PE, or foil laminate film.
Film Rack & Tension Control
Maintains stable web tension before the slitting section. Consistent tension is critical for uniform cut lengths across all six lanes — variance here shows up as uneven sachet sizes.
Is a Six-Lane Machine Right for Your Product?
The SW-A6 is a specialized high-throughput platform for small-portion sachets. It is the right choice only when your combination of fill volume, bag format, and daily output volume justifies the six-lane architecture. Below is a decision framework to confirm fit.
Choose the SW-A6 When:
- Your output is a flat 3-side seal sachet for food-service portion packs — ketchup, soy sauce, mustard, salt, sugar, MSG, hotel amenity, airline catering, fast-food condiment
- Film cost is a primary constraint — single-roll feed and 3-side seal use less film per sachet than the dual-film SW-C6 (right pick for high-volume disposable condiment economics)
- Product is a robust free-flowing liquid, powder, or granule — not oxygen-sensitive or barrier-critical (use the SW-C6 for those)
- Bag width is 30–100 mm and fill volume is 5–30 ml — typical condiment / sugar / salt portion range
- Daily output is high (300,000+ sachets per shift) and bag format is stable across SKUs — sachet dimensions do not change frequently
Choose a Different Machine When:
- Fill volume is larger than 30 ml — use the SW-420F collar type liquid machine for 30–1,000 ml liquids, or the SW-420E/620E auger powder machine for powder up to 500 g
- You need back seal stick sachets instead of 3-side seal — use the SW-B10 ten-column back seal machine
- Bag format or SKU changes frequently — a single-lane machine is faster to re-tool for format changes than a multi-lane platform
- Product is a single solid piece (biscuit, candy bar, soap) — use the SW-350A/450A/550A pillow pouch machine
- You need stand-up pouches or premade bag formats — use the SW-Y premade bag liquid or SW-L premade bag powder machine family
When This Machine Is Not the Right Fit
The SW-A6 is not suitable for highly viscous pastes, sticky or stringy materials, irregular large granules, or products that bridge in a feeder hopper. Multi-lane dosing depends on even product distribution from a central reservoir — if the product does not flow consistently, one or more lanes will under- or over-fill. For sticky or viscous products, consider the SW-Y200 premade bag liquid machine (larger bags with dedicated pump). For irregular granules needing multi-head weigher accuracy, use the SW-420A multi-head weigher machine. For vacuum packaging or barrier-sensitive products, use the SW-130ZK/160ZK vacuum machine.

What Our Clients Say
We ordered the SW-A6 for packing 20 ml strawberry jam sachets for hotel breakfast service. The machine holds six lanes very stably — we see less than 2% fill variance between lanes at production speed. We run around 1,400 sachets per minute in practice, which is about 85% of the theoretical maximum. The piston pump module handles our jam viscosity well; the only tuning we needed was the end-seal temperature for our PET/PE film.
Fatima K.
Production Supervisor — Hotel Amenity Supplier, UAE
The SW-A6 replaced three single-lane coffee stick machines on our production floor. The footprint is much smaller and we only train operators on one HMI instead of three. Output is higher and film waste is lower — one central film roll for six sachets is more efficient than six separate rolls. ShengWei's remote support helped us set up the recipe for our 5 g instant coffee stick within two days of installation.
